Battery Warnings and Guidelines
While the 3S 11.1V 1800mAh Lithium Polymer Battery (EFLB18003S) included with your Blade 400
3D features Charge Protection Circuitry and Balance Charging via the included 3S 11.1V 1.8-Amp
Lithium Polymer Balancing Charger (EFLC3115) to help ensure a safe charge every time, you MUST
read the following safety instructions and warnings before handling, charging or using the Li-Po
battery.
Note: Lithium Polymer batteries are significantly more volatile than the alkaline, Ni-Cd or
Ni-MH batteries used in RC applications. All instructions and warnings must be followed
exactly. Mishandling of Li-Po batteries can result in fire.
By handling, charging or using the included Li-Po battery you assume all risks associated with
lithium batteries. If you do not agree with these conditions, return your complete Blade 400 3D
model in new, unused condition to the place of purchase immediately.
• You must charge the included 3S 11.1V 1800mAh Li-Po battery in a safe area away from
flammable materials.
• Do not charge the battery when installed in the helicopter.
• Never charge the battery unattended. When charging the battery you should always remain in
constant observation to monitor the charging process and react to potential problems that may
occur.
• After ight, the battery must be cooled to ambient temperature before charging.
• You MUST use the included 3S 11.1V 1.8-Amp Li-Po Balancing Charger ONLY. Failure to do so
may result in a re causing personal injury and/or property damage. DO NOT use a Ni-Cd or
Ni-MH charger.
• If at any time during the charge or discharge process the battery begins to balloon or swell,
discontinue charging or discharging immediately. Quickly and safely disconnect the battery,
then place it in a safe, open area away from flammable materials to observe it for at least 15
minutes. Continuing to charge or discharge a battery that has begun to balloon or swell can
result in a fire. A battery that has ballooned or swollen even a small amount must be removed
from service completely.
10
11
• In the event of a crash, you must quickly and safely disconnect and remove the battery from the
model, then place it in a safe, open area away from flammable materials to observe it for at least
15 minutes.
• Store the battery at room temperature and approximately ½ charge (3.8V per cell; 11.4V for a
3S battery pack) for best results.
• When transporting or temporarily storing the battery, the temperature range should be from
40–120 degrees Fahrenheit. Do not store the battery or model in a car or direct sunlight
whenever possible. If stored in a hot car, the battery can be damaged or even catch fire.
• Do not over-discharge the battery. Discharging the battery too low can cause damage to the
battery resulting in reduced performance and duration.
Li-Po cells should not be discharged to below 3V each under load. In the case of the 3S 11.1V
Li-Po battery used for the Blade 400 3D, you will not want the voltage of the battery to fall
below 9V during flight.
The 25-amp brushless ESC installed on your Blade 400 model features a “soft” low voltage cutoff
(LVC) that occurs when the battery reaches 9V under load. When the soft cut-off occurs, the ESC
will automatically reduce power to the motor (regardless of the power level you have set with the
throttle stick/curve) in order to prevent the voltage of the battery from dropping to below 9V. After
the power is reduced and the voltage “rebounds” (rises) to above 9V, the ESC will automatically
return power to the motor until the battery reaches 9V again. This process will continue to repeat,
sometimes causing the motor/power to “pulse” rapidly, helping to provide a visual and/or audible
indication of the low battery voltage. However, in some cases it may be difficult to detect pulsing
of the motor/power, so we suggest that you be extremely aware of the power level of the Li-Po
battery during flight. If at any time the helicopter begins to require more throttle than typical to
maintain hover or flight, or has lost significant power, you must land the helicopter IMMEDIATELY
to prevent a sudden loss in power that could result in a crash.
Although the soft LVC of the ESC will help to prevent “deep” (below 9V; 3V per cell) over-
discharge of the battery, it is not recommended that you continue to run the motor for an extended
length of time after landing and/or noticing a loss of power. Routinely discharging the battery
to 9V can still cause permanent damage to the battery, resulting in shortened flight times, loss of
power output or failure of the battery entirely. It is recommended that you use the timer function of
the DX6i transmitter to keep the duration of each flight consistent and to prevent reaching the soft
LVC each time you fly.
Note: The timer of the DX6i transmitter included with your Blade 400 3D model has been
set for 4 minutes and 30 seconds. Although it is possible to achieve longer flight durations
safely depending on the performance of the battery, flying style of the pilot and other
factors, we suggest using this timer setting for the rst few ights. You can keep track of the
flight duration on subsequent flights and adjust the setting of the timer, as you prefer. Please
see the manual for the DX6i transmitter for more information regarding the timer function.
If you have any further questions or concerns regarding the handling, charging and/or use of the
included Li-Po battery pack, please contact Horizon Hobby’s Product Support staff
at 877-504-0233.
Battery Charging
It is important that you only charge the included 3S 11.1V 1800mAh Li-Po Battery (EFLB18003S)
with the included 3S 11.1V 1.8-Amp Li-Po Balancing Charger (EFLC3115). Your battery is equipped
with special Charge Protection Circuitry and Balance Charge Leads with connector that are only
compatible with this charger. Attempting to charge the battery using another Li-Po charger or non
Li-Po compatible charger could result in serious damage. Please familiarize yourself thoroughly with
the Battery Warnings and Guidelines section before continuing.
The included 3S 11.1V 1.8-Amp Li-Po Balancing Charger will charge a near fully discharged (not
over-discharged) 3S 11.1V 1800mAh Li-Po battery in approximately 1.2–1.5 hours. In some cases
the charge time may be shorter depending on the actual amount of capacity left in the battery after a
flight. NEVER charge the battery unattended.
Note: The Li-Po battery included with your Blade 400 3D will arrive partially charged. For this
reason the initial charge may only take approximately 30–50 minutes.
The charger requires up to 3-Amps of 11.5–15 Volt DC input power that can be supplied by the
optional AC to 12V DC, 3-Amp Power Supply (EFLC4030) for convenient charging anywhere an
AC outlet is available. NEVER attempt to power the charger from an AC outlet without the use of a
proper AC to DC adapter/power supply.
12
13
Input power for the charger can also be supplied by a small 12V gel cell or car battery using the
included wire harness with alligator clips.
The charger is equipped with four LED indicators marked as CELL 1, CELL 2, CELL 3 and CHARGE
STATUS on the label. These LEDs indicate the following (also found on the label of the charger):
• Red Solid CELL STATUS LEDs and Red Flashing CHARGE STATUS LED: Input power connected,
battery to charge not connected
• Green Solid CELL Status LEDs and Red Solid CHARGE STATUS LED: Battery to charge connected
and charging, balance between cells OK
• Yellow Solid CELL STATUS LED and Red Solid CHARGE STATUS LED: Charging and balancing cell
with yellow LED
• Red Solid CELL STATUS LEDs and Red Solid CHARGE STATUS LED: Charge complete
• Red and Green Flashing CELL STATUS LEDs and Red Solid (or ashing) CHARGE STATUS LED:
Charge error
Use care to ensure proper polarity (as marked on the bottom of the charger case) when connecting
the charger to a power source. Once you have connected the charger to the power source, its CELL
STATUS LEDs will glow solid red and the CHARGE STATUS LED will flash to indicate the charger has
power and is ready to begin charging. Connect the Li-Po battery to the charger using the specially
marked Balance Charge Lead exiting the battery and the mating connector on the side of the charger
labeled with 11.1V. The balance connector is keyed to prevent reverse polarity connection.
Note: Be sure to place the battery and charger on a smooth, heat-resistant surface during charging.
When the battery is properly connected and charging normally, the CHARGE STATUS LED will glow
solid red and the CELL STATUS LED indicators will glow solid green when the voltage balance between
the cells is OK. If the CELL STATUS LED for any cell is glowing yellow while the CHARGE STATUS LED is
solid red, the indicated cell will be balanced (charged) so its voltage closely matches that of the other
two cells and the “full” charge voltage. Once the battery has been fully charged, the CELL STATUS and
CHARGE STATUS LEDs will glow solid red. The battery can now be removed from the charger and
installed in the Blade 400 3D for flight.
14
15
Charge Errors and Indications
In the event that any CELL STATUS LED flashes red and green while the CHARGE STATUS LED glows
solid or flashes red, a charge error has occurred. Some examples of charge errors include:
• If any CELL STATUS LED ashes red and green while the CHARGE STATUS LED ashes red, the
voltage of the indicated cell(s) is below 2.5V. In this case the voltage of the indicated cell(s) is too low
to allow the charge process to begin.
If only one or two CELL STATUS LEDs flash red and green (while the CHARGE STATUS LED flashes
red), the balance connector connections for the indicated cell(s) may not be making good contact
with the charger’s mating connector. Be sure to double-check the connections to ensure they are
making good contact. If the connections are making good contact, the indicated cell(s) may have
failed or dropped to a voltage that no longer allows the battery to be charged safely.
In the event that all three CELL STATUS LEDs flash red and green (while the CHARGE STATUS LED
flashes red), the battery was likely overdischarged. Although the Electronic Speed Control (ESC)
installed on your Blade 400 3D model is programmed to help prevent deep overdischarge of the
Li-Po battery, you must exercise proper care of the battery if it is used in another application. You
must also be sure that the battery is never left plugged into the ESC for an extended period of time
after flying in order to prevent overdischarge.
Anytime one or more CELL STATUS LEDs flash red and green while the CHARGE STATUS LED
flashes red, you should remove the Li-Po battery from service and replace it with a new one.
• If any CELL STATUS LED ashes red and green while the CHARGE STATUS LED glows solid red, the
charge process for the indicated cell(s) has been interrupted. In this case, the balance connector
connections for the indicated cell(s) may not be making good contact with the charger’s mating
connector. Double-check the connections to ensure they are making good contact, and then begin
the charge process again.
If you have any further questions or concerns regarding charge error indications, please contact
Horizon Hobby’s Product Support staff at 877-504-0233
Installing the Transmitter Batteries
Install the 4 included AA batteries in the Spektrum DX6i transmitter. Check the power level of the
batteries and operation of the transmitter by switching the power switch on (to the right). The voltage
display on the LCD screen at the bottom of the transmitter will indicate the power level of the batteries.
If at any time the voltage of the batteries falls to 4.3V or less, an alarm will sound, and it will be
necessary to replace the batteries with new ones.
16
17
Installing the Flight Battery
Use the included hook and loop material for mounting the Li-Po battery. We suggest installing the
“loop” (fuzzy) material on the battery and the “hook” material on the battery support located at the
front of the main frame. Install the hook and loop material on the battery so the main power wire
leads with the blue EC3 connector are oriented to the right side of the helicopter (when viewing the
helicopter from behind). This will help to keep the wire leads from interfering with the elevator servo on
the left side of the model.
Also, be sure that the battery is positioned so that it will not come into contact with the elevator servo
arm and the motor case. If the battery comes into contact with either of these components during flight,
it can result in damage to the battery, motor and/or servo, potentially resulting in a crash.
Once the battery has been properly positioned, fasten the hook and look strap around the battery for
added security.
Control Test
Although each Blade 400 3D model is control tested at the factory, it is a good idea to test the controls
prior to the first flight to ensure none of the servos, linkages or other parts were damaged during
shipping and handling. Before proceeding, disconnect the three bullet connectors between the motor
and ESC. It is not safe to perform the control test with the motor connected to the ESC.
Turn the transmitter on first and lower the throttle/collective (left-hand) stick completely.
18
19
Then, plug the battery into the battery lead of the ESC.
Position the helicopter to view it from the left or right side. Move the left-hand stick up and down to
check the collective pitch control. When the stick is pushed up, the swashplate should lower, increasing
the pitch of the main blades.
With the stick pulled back down, the swashplate should raise, decreasing the pitch of the main blades.
Again viewing the helicopter from the left or right side, move the right-hand stick forward and aft to
check elevator pitch control. When the stick is pushed forward, the swashplate should also tilt forward.
With the stick pulled back, the swashplate will tilt toward the rear.
While viewing the helicopter from the rear (tail boom toward you), move the right-hand stick left and
right to check aileron roll control. When the stick is pushed to the left, the swashplate should also tilt
left.
With the stick pushed right, the swashplate will tilt to the right.
While viewing the helicopter from the rear (tail boom toward you), move the left-hand stick left and
right to check rudder/tail rotor pitch control. When the stick is pushed to the left, the tail pitch slider
should move to the right.
With the stick pushed right, the tail pitch slider should move to the left.
20
21
If at any time during the test the swashplate controls do not respond properly, double-check the
swashplate mixing (SWASH MIX) settings in the transmitter (see the manual for the DX6i for more
information). The values should be set as follows:
AILE -75%
ELEV -75%
PITCH +85%
If the swashplate controls still do not respond properly after ensuring that the swashplate mixing values
are correct, or if the rudder/tail rotor pitch control is not responding properly, double-check the servo
reversing (REVERSE) settings in the transmitter (see the manual for the DX6i for more information).
They should be set as follows:
THRO – N (Normal)
AILE – R (Reverse)
ELEV – N (Normal)
RUDD – R (Reverse)
PITC – N (Normal)
If the controls still do not respond properly after ensuring the servo reversing switch positions are
correct, you may also check the servo connections to the receiver. The connection for each servo (when
viewing the helicopter from behind) should be connected to the receiver as follows:
AILE – Lower rear-mounted swashplate control “aileron” servo
ELEV – Forward-mounted swashplate control “elevator” servo
RUDD – Rear-mounted tail rotor pitch control “rudder” servo
AUX1 – Upper rear-mounted swashplate control “pitch” servo
Once you have confirmed proper swashplate mixing values, servo reversing settings and servo
connection locations, all controls should be functioning properly. However, if you continue to encounter
any problems relating to your Blade 400 3D responding properly to the transmitter, do not fly. Call
Horizon’s Product Support staff at 1-877-504-0233 before proceeding.
If you have confirmed proper control operation of your Blade 400 3D, unplug the flight battery from
the ESC and reconnect the three bullet connectors between the motor and ESC, taking care to connect
the like-color leads to one another (black to black, blue to blue and red to red) to ensure proper
operation of the motor.
Electronic Speed Control (ESC) Features, Arming and Motor Control Test
Your Blade 400 3D model is equipped with a 25-amp brushless ESC that is specifically designed for
use in helicopter models.
The ESC is not programmable for use in other applications, however, it is equipped with features and
functions that optimize its performance for the Blade 400. These features and functions include:
• “Soft” Low Voltage Cutoff
The ESC features a “soft” low voltage cutoff (LVC) that occurs when the battery reaches
approximately 9V under load. This helps to prevent “deep” overdischarge of the Li-Po battery
during use. Please see the Battery Warnings and Guidelines section for more information
regarding the soft LVC feature and how to prevent overdischarge of the Li-Po battery.
• Soft (Slow) Start
The soft (slow) start function of the ESC is intended to help prevent potential damage of the
geartrain, motor and ESC by softly (slowly) “ramping up” (increasing) power to the motor
(particularly when the rotor blades are not already spinning). The first time you “power up” the
ESC after it has been powered on and armed, it will take approximately 15 seconds for the ESC/
motor to reach the power level you initially set with the throttle stick/curve. This means you will
need to wait approximately 15 seconds before attempting any aggressive maneuvering as you
should allow the power system to reach the set level of power first.
Any time (after the initial soft startup occurs) the ESC/motor have been powered down
completely (to 0% power) for approximately 15 seconds or more, the soft start will occur again.
This is particularly helpful if you land the helicopter to make an adjustment as you will not need
to re-arm the ESC in order to perform a soft startup. It is simply best to wait approximately 15
seconds before powering up the ESC/motor again for flight.
• Fast Start
The fast start function of the ESC is intended to allow any level of power to be applied almost
immediately after ESC/motor have been powered down completely (to 0% power) for any
amount of time less than approximately 15 seconds. This is particularly helpful if you accidentally
bump the Throttle Hold switch or when aborting an auto-rotation attempt as it will allow the
ESC/motor to reach any power level you have set with the throttle stick/curve almost immediately
when the Throttle Hold switch is set back to the OFF (0) position.
The following checklist includes the steps you must follow to ensure proper arming and operation of the
ESC (as well as proper operating direction of the motor and rotor blades):
q Each time before you fly you must ALWAYS turn on the transmitter power first before connecting
the flight battery to the ESC. Never connect the flight battery to the ESC before powering on
the transmitter first. After each flight, be sure that you never turn off the transmitter before
disconnecting the flight battery from the ESC first.
Note: The antennas exiting the Spektrum AR6100e receiver should extend outward (to the
left and right of the helicopter) as much as possible for the best overall performance. Be sure
to double-check the position and orientation of both antennas before each flying session,
especially if the helicopter was taken out of a box or carrying case.
q The throttle (left-hand) stick MUST be in the lowest possible position, with the throttle trim set in
approximately the middle position, in order for the ESC to arm. Also, the Flight Mode (F MODE)
switch must be in the “Normal” (0) position with the switch toggled toward the back of the
transmitter. The Throttle Hold (TH HOLD) switch should be set in the “Off” (0) position, however,
the ESC will still arm if the switch is set in the “On” (1) position and the “Hold” throttle curve
values are all set to 0%.
Note: In some cases it may be possible to arm the ESC with the throttle stick set to a position
that is higher than the lowest possible position. While the ESC may still function in this
situation, it is best to re-arm the ESC with the throttle stick in the lowest possible position in
order to ensure the best performance of the ESC overall.

q After confirming that the transmitter has been turned on and has an adequate level of battery
power (as displayed on the LCD screen at the bottom of the transmitter), and that the throttle stick
is in the lowest possible position, it is now safe to connect the flight battery to the ESC.
q With battery power applied, you will hear two “beeps” once the ESC has armed properly. Use
caution as the motor, main rotor and tail rotor blades will now run with throttle stick input. For
safety, we suggest setting the Throttle Hold (TH HOLD) switch in the “On” (1) position once the
ESC has armed. This will keep the motor and rotor blades from running while you handle the
helicopter and transmitter (as long as the throttle curve values for the “Hold” flight mode are all
set to 0%, as they are from the factory).
If you have not set the Throttle Hold switch to the “On” position, or after you set the switch to the
“Off” (0) position, DO NOT advance the throttle stick until you are clear of the rotor blades.
Note: If you do not hear two beeps after battery power is applied, the ESC has not armed properly.
Please review the following:
q Confirm that the throttle stick is in the lowest possible position and that the throttle trim is set in
approximately the middle position.
q Confirm that the Flight Mode (F MODE) switch is set to the “Normal” (0) position.
q Confirm that the low (L) position (POS) value for the normal (NORM) throttle curve (THRO CUR)
is set to 0%.
q Conrm that the travel adjustment (TRAVEL ADJ) value for the throttle (THRO) channel is set to
100% in the low position.
If the ESC will not arm after confirming the details listed above, contact Horizon Hobby’s Product
Support staff at 1-877-504-0233 before proceeding.
q Once you have placed the helicopter in a safe area, free of obstructions, and are clear of the
rotor blades, you can safely begin to power up the model to confirm proper operation and
operating direction of the motor and rotor blades.
q Advance the throttle stick slowly, just until the motor and rotor blades begin to spin. Note the
direction that the main and tail rotor blades spin. The main rotor blades should spin clockwise
when viewed from the top, and the tail rotor blades should spin counterclockwise when viewed
from the right-hand side of the helicopter. If both sets of rotor blades are operating in the wrong
direction, power down the helicopter, unplug the flight battery, then simply reverse the position of
any two motor wire lead connections to the ESC.
Note: If the main rotor blades are operating in the correct direction but the tail rotor blades
are not, the belt driving the tail rotor may be “twisted” in the wrong direction. To correct this,
remove the tail rotor case and parts from the tail boom and pull the belt “straight” (so it is
horizontal and has no twists). Then, rotate the belt 90 degrees clockwise when viewing the
helicopter from behind.
Reinstall the tail rotor case and other parts, then, double check proper operating direction of the
tail rotor blades by spinning the main rotor blades in the clockwise direction (when viewed from the
top) by hand. The tail rotor blades should now spin counterclockwise (when viewed from the righthand side of the helicopter).
q After confirming that both sets of rotor blades are operating in the correct directions, please be
sure to review the following sections of the manual BEFORE proceeding with the first flight.
Gyro Initialization, Response Test and Adjustment
Your Blade 400 3D model is equipped with an E-flite G110 Micro Heading Lock Gyro. This gyro offers
an excellent blend of size, weight, features and performance.
Set throttle stick in
lowest position
24
25
Initialization and Response Test
The following checklist includes the steps you must follow to ensure proper initialization and
operation of the gyro:
q After connecting the flight batter y to the ESC, be sure that you do not move or sway the
helicopter. Allow it to remain motionless until the red LED on the gyro illuminates solidly,
indicating that the gyro has initialized properly and is ready for use.
Note: It is extremely important that you do not move or sway the helicopter
after powering it on and before the gyro initializes. The gyro must be allowed
adequate time to record the neutral position in order to initialize for proper
operation. If you accidentally move the helicopter after powering it on and before
the gyro initializes, power the helicopter off (by disconnecting the flight battery
from the ESC) then repeat the process to power the helicopter on and to initialize
the gyro properly.
q Once the gyro has initialized properly, we suggest setting the Throttle Hold (TH HOLD) switch
to the “On” (1) position for added safety during the response test.
q Before making your first flight, it will be necessary to confirm that the gyro is responding
properly to the movements of the helicopter and providing proper inputs to the tail servo in
order to counteract any unwanted changes in yaw. To do this, view the servo arm (from the
top of the servo) and note the direction the arm rotates when you give a right rudder input on
the transmitter (while the model remains motionless). In the case of the DS75H servo installed
on your Blade 400 model, the servo arm should rotate toward the front of the helicopter.
Then, yaw the nose of the helicopter quickly to the left, while again noting the direction
the tail servo arm rotates. The arm should rotate in the same direction as it did for a right
rudder command (toward the front of the helicopter). If the servo arm rotates in the opposite
direction, switch the position of the Reverse switch located on the side of the gyro. The switch
should be set to the Normal (NOR) position. Then, repeat the steps above to confirm that the
gyro is now providing proper inputs to the tail servo.
q After confirming that the gyro is providing proper inputs to the tail servo, power off the helicopter
and be sure to review the following sections of the manual BEFORE proceeding with the first
flight.
Gyro Mode and Gain Adjustments:
• The G110 offers a Dual Remote Gain Adjustment feature. This, along with the DX6i’s Gyro
Sensitivity feature, allows the gyro mode (Standard Rate or Heading Lock) and gain values to
be set remotely in the transmitter. This means that the Gain Setting Adjustment Pot located on the
gyro itself will not be active and will not be used for adjusting gain values.
• The gain values for the gyro are adjusted in the Gyro Sensitivity (GYRO) menu of the transmitter.
And because the switch (SW) selection choice has been set to the Gyro (GYRO) switch, the two
available gain values can be selected using this switch during flight. When the Gyro switch is
toggled in the upward (0) position, the gain value will be equivalent to the Rate (RATE) set on the
first (0:) line. When the Gyro switch is toggled in the downward (1) position, the gain value will
be equivalent to the Rate (RATE) set on the second (1:) line. Please see the manual for the DX6i for
any additional information you may require.
• When the Rate for either Gyro switch position is set to 0%, it is equivalent to an approximately
100% gain value in the Standard Rate (non-Heading Lock) mode.
When the Rate for either Gyro switch position is set to 25%, it is equivalent to an approximately
50% gain value in the Standard Rate (non-Heading Lock) mode.
When the Rate for either Gyro switch position is set to 50%, it is equivalent to an approximately
0% gain value in the Standard Rate (non-Heading Lock) mode.
• When the Rate for either Gyro switch position is set to 75%, it is equivalent to an approximately
50% gain value in the Heading Lock mode.
When the Rate for either Gyro switch position is set to 100%, it is equivalent to an approximately
100% gain value in the Heading Lock mode.
In the case of the Blade 400 3D, it is generally preferred to fly with the gyro set to the Heading
Lock mode. This means that the Rate for either Gyro switch position should not typically be set to
below approximately 60% (an approximately 20% gain value in the Heading Lock mode).
• While you can set and select between two different Modes and Rates using the Gyro switch,
two slightly different Rates have been set for the same Mode (Heading Lock) from the factory.
The Rate/value is slightly higher when the Gyro switch is set in the upward (0) position than it
is in the downward (1) position. After your first few flights you can experiment with different
values in each position to find the values that work best depending on your flying style and
flying conditions. For example, it may be desirable to use a higher gain value when flying in the
Normal flight mode, and/or a lower gain value when flying in windy conditions. The DX6i also
allows you the option to set gain values for each specific flight mode. This can be accomplished
by setting the gyro switch (SW) selection to Flight Mode (F. MODE) (please see the manual for the
DX6i for more information.)
• During your rst ight, establish a stable hover and apply some short and quick rudder inputs
while observing the reaction of the tail when the control stick is returned to its neutral position. If
there is any tendency for the tail to twitch quickly (oscillate) from side to side, it will be necessary
to lower the Rate used for the selected Gyro switch position.
The goal when adjusting the Rate for one or both of the Gyro switch positions is to nd the highest
gyro gain value (Rate) at which the tail of the helicopter will not oscillate in nearly all areas of
flight, including fast forward flight and descents. In some cases it may not be possible to use
the same Rate for hovering (in the Normal flight mode for example) and fast forward flight/
aerobatics (in the Stunt flight mode for example). By setting two different Rates for each Gyro
switch position, it will allow you to select the best Rate (using the Gyro switch) depending on the
flight mode you are using and the type of flying you are doing at any given time. This can be
particularly helpful when flying in windy conditions, as it may sometimes be necessary to switch to
a lower Rate in flight to prevent significant tail oscillation when performing certain maneuvers.
Trim Adjustments
• During ight, it may be necessary to make some small adjustments to the rudder trim in order to
prevent the nose/tail of the model from “drifting” to the left or right when the rudder stick is in the
neutral position. Typically, only a small amount of adjustment may be necessary.
Note: It is always best to avoid sudden temperature and environmental condition changes
when using a gyro. For example, it is best to not fly a model on a very hot (or cold) day
immediately after removing it from an air-conditioned (or heated) vehicle. It is also best to keep
the gyro out of direct sunlight and away from any heat-generating sources on the model.
To help the gyro better acclimate to temperature and environmental conditions at the flying field,
it is best to let your Blade 400 3D model stand for approximately 10–15 minutes before flying,
allowing the temperature of the gyro sensor to stabilize. If you do not allow the temperature to
stabilize, you may experience radical trim changes that require signicant adjustments of the
rudder trim during flight.
26
27
Servo Mode Setting
• The G110 is equipped with a switch and software that allows its performance to be optimized for
use with most analog and some digital servos. The Servo Mode selection switch can be found on
the side of the gyro.
• When the Servo Mode selection switch is set in the Standard (STD) position, the gyro is optimized
for use with most analog servos. It is also optimized for use with digital servos that are not
designed to accept a pulse rate of 275Hz or higher. And although the DS75H rudder/tail servo
installed on your Blade 400 3D model is a digital servo, it is not designed to accept a pulse
rate of 275Hz. As a result, you must be certain that the Servo Mode selection switch is set to
the Standard position when the DS75H servo is being used.
Note: Do not use analog or digital servos that are not designed to accept a pulse rate of 275Hz
with the Servo Mode selection switch set to the Digital Servo (DS) position. If either type of ser vo
is used with the gyro set to the Digital Servo mode, it will reduce the operating life of the servo,
typically causing the servo to fail within a few minutes of use or after a few flights.
• When the Servo Mode selection switch is set in the Digital Servo (DS) position, the gyro is
optimized for use with digital servos that are designed to accept a pulse rate of 275Hz. Some
such servos include the Spektrum DSP60 and DSP75, as well as the JR 3400G. Again, although
the DS75H tail servo installed on your model is a digital servo, it is not designed to accept a pulse
rate of 275Hz. Be certain that the Servo Mode selection switch is set to the Standard position
when the DS75H servo is being used.
Understanding the Primary Flight Controls
If you are not familiar with the primary flight controls of your Blade 400 3D, please take a few minutes
to familiarize yourself with them before proceeding and before attempting your first flight.
The left-hand stick on the transmitter controls both throttle/collective pitch (climb/descend) and
rudder (yaw left/right). When the left-hand stick is in the lowest position and the throttle trim is set to
approximately the middle position, the motor and rotor blades will not spin (when in the Normal or
Throttle Hold flight mode). Advancing the stick upward will increase the speed and pitch of the main
rotor blades. Increasing the speed and pitch of the main rotor blades will cause the model to climb.
Decreasing the speed and pitch of the main rotor blades by lowering the left-hand stick will cause the
model to descend.
Note: When you are in the Stunt/Idle Up flight mode, lowering the left-hand stick will actually
cause the speed of the main rotor blades to increase while also increasing the amount of negative
pitch the main rotor blades can offer. This allows the model to be flown inverted and to perform
aerobatics like loops, rolls and 3D flying.
After lifting the model off the ground you can balance the throttle/collective pitch by carefully moving
the left-hand stick up and down so that the model will hold a stationary hover without climbing or
descending.
Also, in most cases it will not be necessary to adjust the throttle trim from the middle position for any
reason.

Moving the left-hand stick to the left will turn (yaw) the nose of the helicopter to the left about the axis
of the main shaft. This is accomplished by changing the pitch of the tail rotor blades.
Moving the stick to the right will turn (yaw) the nose of the helicopter to the to the right about the axis
of the main shaft.
The rudder trim can be used to help keep the nose of the helicopter from rotating to the left or right
when in hover with no rudder stick input. For example, if the nose of the helicopter drifts to the right
when in hover, click the rudder trim lever to the left until the nose stays as close to straight as possible.
The right-hand stick controls both elevator (pitch fore/aft) and aileron (roll). Pushing the stick forward
will pitch the nose of the helicopter downward, allowing the helicopter to be flown forward and to
perform forward flips.
Pulling the stick backward will pitch the tail of the helicopter downward, allowing the helicopter to be
flown backward and to perform backward flips.
The elevator trim can be used to help keep the helicopter from drifting forward or backward when in
hover with no elevator stick input. For example, if the helicopter drifts forward when in hover, click the
elevator trim lever downward until the helicopter hovers as level as possible with no forward drifting.
Moving the stick to the left will roll the helicopter to the left, allowing the helicopter to be flown to the
left and to perform left-hand rolls.
Moving the stick to the right will roll the helicopter to the right, allowing the helicopter to be flown to
the right and to perform right-hand rolls.
The aileron trim can be used to help keep the helicopter from drifting left or right when in hover with
no aileron stick input. For example, if the helicopter drifts to the right when in hover, click the aileron
trim lever to the left until the helicopter hovers as level as possible with no drifting to the right.
Once you have become familiar with the primary controls of the helicopter, you are almost
ready to fly.

Normal and Stunt Flight Modes
The Spektrum DX6i transmitter included with your Blade 400 3D features a Flight Mode (F. MODE)
switch. This switch allows the pilot to toggle between the “Normal” (0) and “Stunt/Idle Up” (1) flight
modes during flight.
When the Flight Mode switch is toggled toward the rear of the transmitter (position 0), the Blade 400
3D will be in the Normal (NORM) flight mode. In this flight mode, the throttle curve is linear from 0%
to 100%, with a pitch range of approximately -3 degrees (35%) to +10 degrees (100%). This is the
preferred flight mode for general hovering and basic (non-aerobatic) flight.
When the Flight Mode switch is toggled toward the front of the transmitter (position 1), the Blade 400
3D will be in the Stunt/Idle Up (STUNT) flight mode. In this flight mode, the throttle curve is “V” shaped
from 100% to 100% with 85% throttle at mid-stick, with a pitch range of -10 (0%) to +10 degrees
(100%). This is the preferred flight mode for most forward/backward, aerobatic and 3D flying.
Note: When in the Stunt flight mode, even with the throttle stick pulled all the way down to its
lowest possible position, the motor and rotor blades will continue to spin aggressively. You must
use the Normal flight mode (or Throttle Hold) to safely power down the motor and rotor blades. For
added safety, the ESC will not arm if the flight battery is plugged in and the flight mode switch is set
to the Stunt position.
When switching between the Normal and Stunt flight modes, it is typically best to do so in the air while
hovering. The throttle and pitch curves of each flight mode have been optimized to transition smoothly
around hover.
Note: Although the midpoint (point 3) of the throttle curve in the Stunt flight mode has been factoryset to 85% to provide good overall sport and 3D aerobatic performance, this value (as well as the
values for points 2 and 4) can easily be adjusted to better suit the pilot’s preference. Pilots new to
this class of model, or those that may not require the most aggressive performance, may prefer to
reduce the value of the midpoint to approximately 70%. This will reduce the headspeed in upright
and inverted hover, as well as at mid-stick, often times helping to make it easier (smoother) and less
intimidating to fly the model. However, if you reduce the value of the midpoint (point 3), it will also
be necessary to adjust the values of points 2 and 4 in order to achieve the best performance. In

general, it is usually preferred to simply “split the difference” between the values of the lowest point
(point L) and the midpoint (point 3), as well as the highest point (point H) and the midpoint. For
example, if the lowest and highest points are set to 100%, and the midpoint is set to 70%, points 2
and 4 should be set to 85%.
Pilots interested in the most aggressive performance for added cyclic and collective pitch response
may prefer to increase the value of the midpoint (as well as the values for points 2 and 4 as
necessary). Please see the manual for the DX6i for more information on throttle curve settings
and adjustments.
Throttle Hold
The Spektrum DX6i transmitter also features a Throttle Hold (TH HOLD) switch. This switch allows the
pilot to toggle between the Throttle Hold “Off” (0) and Throttle Hold “On” (1).
When the Throttle Hold switch is toggled toward the rear of the transmitter (position 0), Throttle Hold
will be “Off.” When Throttle Hold is off, the transmitter will be in the Normal or Stunt flight mode
(depending on the position in which the F MODE switch is set).
When the Throttle Hold switch is toggled toward the front of the transmitter (position 1), Throttle Hold
will be “On” (activated). When Throttle Hold is on, the helicopter will be in the Throttle Hold (HOLD)
flight mode. In this flight mode, the throttle curve is linear from 0% to 0%. In the case of an electricpowered model like the Blade 400, this will power down the ESC/motor completely. And, because
the pitch range in this flight mode is approximately -3 degrees (35%) to +10 degrees (100%), it also
allows you to perform auto-rotations during flight if you choose.
Toggling the Throttle Hold switch to the on position also allows you to safely power down the ESC/
motor any time the helicopter is not flying. This is particularly helpful as it allows you to safely handle
the helicopter, while the ESC is still armed, regardless of the throttle/collective stick and Flight Mode
switch positions.
Note: If the Throttle Hold switch is in the on position, and the throttle/collective stick set to anything
above the lowest possible position with the Flight Mode switch set to the Normal position, the ESC/
motor will power up as soon as the Throttle Hold switch is set to the off position. This is also the
case regardless of the throttle/collective stick position when the Flight Mode switch is set to the Stunt
position. You must exercise extreme care and caution when switching the Throttle Hold switch to the
off position. You should always be in the Normal ight mode and have the throttle/collective stick
set to the lowest possible position BEFORE switching Throttle Hold off.

Before the First Flight
Although each Blade 400 3D model is factory assembled and tested, you should check the following
before making your first flight:
q Check the security of all screws and control/linkage balls on your model. Tighten any screws and
control/linkage balls that may be loose and replace any screws, control/linkage balls or other
parts that may be stripped.
q Check to be sure that the screws securing the main and tail rotor blades in the blade grips are
tightened so that the blades can pivot in the grips when moderate pressure is applied.
q Check the security of all the plastic ball link ends on your model. The links should stay attached
to the control/linkage balls even when moderate force is applied. Any link that does not stay
attached to the control/linkage ball should be replaced before flight.
q Check to be sure that all electronic equipment and wire leads are secure and will not come into
contact with any moving parts.
q Check for proper tail rotor drive belt tension. Proper belt tension plays a critical role in achieving
maximum performance and reliability of your model.
If the belt tension is set too tight, it can result in a loss of power while also causing the belt and/
or pulleys to wear more quickly.
If the belt tension is set too loose, the belt can skip and strip teeth from the belt and/or pulleys. It
can also result in a loss of tail rotor performance and control in flight.
You can check the tension of the tail rotor drive belt by using an Allen/hex wrench (or any other
suitable tool/device) to compress the belt through the opening in the main frame and tail boom located
on the right side of the model. Apply light pressure to the exposed side of the belt, compressing it
toward the other side of the belt. The belt tension is set properly if the compressed side of the belt
reaches approximately ½ of the way to the other side of the belt.
If the compressed side of the belt reaches more than ½ of the way to the other side of the belt, the
tension is set too loose. If it is difficult to compress the exposed side of the belt, or if it does not reach
approximately ½ of the way to the other side of the belt, the tension is set too tight.
You can adjust the belt tension by loosening the two screws that mount the horizontal stabilizer and the
four screws that hold the rear section of the main frame together around the tail boom. After loosening
these six screws, slide the boom further into the frame (to loosen belt tension) or farther out of the
frame (to tighten belt tension). After properly adjusting the tail drive belt tension, be sure to retighten
all six screws while also confirming proper alignment of the horizontal stabilizer and tail rotor shaft
(both should be level/horizontal and perpendicular to the main shaft when viewed from behind the
model).
q If this is the first test flight, or a test flight following repairs, you will also want to center the rudder,
aileron and elevator trims.
Your Blade 400 3D is now ready for flight.
Choosing a Flying Area
When you are ready for your first flight, you will want to select a large, open area that is free of
people and obstructions. Until you have properly trimmed, adjusted and become familiar with the
handling of the Blade 400 3D, we suggest that your first and subsequent test flights be made outdoors
in low-wind conditions only.
While it is possible for the Blade 400 3D to be flown indoors, we suggest that it only be in a very large
indoor facility such as a gym (with proper approval) that is also free of people and obstructions. The
Blade 400 3D is not intended to be flown in small indoor areas or facilities where it may be possible to
fly a micro coaxial helicopter like the Blade CX or Blade CX2, or a micro collective pitch helicopter like
the Blade CP+ or Blade CP Pro.
Flying the Blade 400 3D
Having followed the proper ESC and gyro arming and initialization procedures, confirmed proper
control of the servos and motor, and found a suitable flying area, your Blade 400 3D is ready for
flight.
• Slowly raise the throttle/collective pitch (left-hand) stick, increasing the speed of the main rotor
blades until the model begins to lift off. Do not raise the throttle stick too quickly as the model could
climb too fast causing you to lose control or make contact with objects above.
• Lift the model off the ground just a few inches and concentrate on balancing the throttle stick position
so that the model holds a steady hover altitude. In some cases it may be best to make a few short
“hops” to an altitude of just a few inches until you become familiar with the control inputs and trim
settings required to maintain a steady hover and altitude.
36
37
As you will nd, the Blade 400 3D requires minor throttle/collective pitch adjustments to maintain its
altitude in hover. Remember to keep these adjustments as minimal as possible as large adjustments
could result in a loss of control and/or a possible crash.
• While attempting to establish a low-level hover, you can also check to see if any trim adjustments
are required to help keep the Blade 400 3D from constantly drifting in various directions. If you find
the helicopter constantly drifts without any directional control input, it will be best to land the model
before making any adjustments to the trim levers. Additional details regarding the location and
function of the trim levers can be found in the “Understanding the Primary Flight Controls” section of
this manual.
If the nose of the helicopter is drifting to the left or right, you will need to adjust the rudder trim.
If the helicopter is drifting forward or backward, you will need to adjust the elevator trim.
If the helicopter is drifting to the left or right, you will need to adjust the aileron trim.
Continue to make trim adjustments until the helicopter can hover at a low altitude with very little
drifting and directional control input.
• Once you have the Blade 400 3D properly trimmed and maintaining a stable low-level hover,
practice using the rudder, elevator and aileron controls to get a feel for how the helicopter responds
to control inputs. Remember to keep the control inputs as minimal as possible to prevent overcontrolling the helicopter, especially when in hover.
• After becoming comfortable with hovering the Blade 400 3D at low-levels of altitude just a few
inches off the ground, you can transition to hovering and flying the helicopter at higher altitudes of
approximately three to four feet. At these higher altitudes you will be able to get a feel for the flight
characteristics of the Blade 400 3D when it is flying out of “ground effect.”
• If at any time during ight you feel like the helicopter is driting out of control, it is best to return all
controls to neutral and to lower the throttle stick completely or activate Throttle Hold. This will help
reduce the amount of damage that may be caused in the event of a crash.
Failure to lower the throttle stick to the lowest possible position (in the Normal Flight mode only) or to
activate Throttle Hold (in any flight mode) in the event of a crash could result in damage to the ESC.
While the ESC is readily capable of handling all in-flight power loads, and even brief momentary
bursts beyond these typical loads, it can be damaged if an excessive amount of current is pulled
through it for an extended period of time. This period of time may vary depending on conditions, so it
is best to keep any momentary overloads as short as possible in order to prevent damage to the ESC.
Note: Crash damage is not covered under warranty.
• It is extremely important when hovering and ying the Blade 400 3D to be aware of the power level
of the Li-Po battery pack. If at any time the helicopter begins to require more throttle than typical to
maintain hover or flight or has lost significant power, you must land the helicopter IMMEDIATELY to
prevent a sudden loss in power that could result in a crash.
Main Rotor Blade Tracking Adjustment
Caution: Be sure to maintain a safe distance from the helicopter (10–15 feet) when tracking the
main rotor blades.
Blade tracking is a critical element to the ight performance of just about any helicopter, including
the Blade 400 3D. Main rotor blades that are out of track may cause vibration, instability, and loss
of power due to increased drag. Although the main rotor blades of each Blade 400 3D model are
tracked at the factory, minor adjustments to blade tracking may be required after blade changes,
linkage adjustments or repairs.
To check main rotor blade tracking and make any required adjustments, please note the following tips:
• Before proceeding with the test ight of a new model, or any model to which changes or repairs
have been made, be certain that the main rotor blades have been properly installed and secured.
The main rotor blade mounting bolts should be tightened so the blades can pivot in the blade grip
when moderate pressure is applied. Never allow the main rotor blades to swing freely in their grips.
• After powering the model on and allowing the ESC and gyro to properly arm and initialize, bring
the main rotor blades of your Blade 400 3D up to speed. You can check the blade tracking either on
the ground or in the air at approximately eye level. It might be a good idea to have an assistant on
hand to help sight the blades. Again, be certain to maintain a safe distance of 10–15 feet from the
helicopter when checking the tracking of the main rotor blades.
• Once the main rotor blades have been brought up to speed, note which blade is running low and
which blade is running high (by the colored tracking tape).

• After conrming which blade is running low and which blade is running high, power down the
helicopter in order to make any necessary adjustments to the linkages. You can increase the pitch of
the low blade by shortening the “mixing arm to inner swashplate linkage.” This is accomplished by
turning one of the Ball Link ends in by one-half to one full turn at a time. Or, you can decrease the
pitch of the high blade by lengthening the same linkage.
Note: The blade you choose to raise or lower when making tracking adjustments will depend on
the pitch of each blade. Because both rotor blades should be as close to 0 degrees as possible
when Throttle Hold is activated (DO NOT attempt to check for 0 pitch in the Normal or Stunt/Idle
Up flight modes) and the throttle/collective stick is in the middle position, you can easily identify
which rotor blade to adjust. If one blade is “lower” than 0 degrees, raise it to match the other
blade. If one blade is “higher” than 0 degrees, lower it to match the other blade.
Typically, not much adjustment should be necessary to properly track the main rotor blades. If
signicant adjustments are required, be sure to double-check the length of both mixing arm to inner
swashplate linkages (they should be close to the same length). You should also check the blades for
any warps or twists. In most cases, you should be able to get both blades tracking perfectly in the
same plane. However, due to slight variations in the ball links and threaded linkage rods/pushrods
it may not always be possible to achieve absolutely perfect blade tracking. Don’t worry, as the
helicopter should still perform well as long as the blade tracking is adjusted as closely as possible.
Flybar Paddle Tracking Adjustment
While main rotor blade tracking is a critical element of flight performance, proper flybar paddle
tracking and positioning is also important in maintaining proper control response and vibration-free
operation.
To check ybar paddle tracking, positioning and to make any necessary adjustments, please note the
following tips:
• Conrm that both ybar paddles are equally spaced from the ends of the ybar paddle control
frame arms. If they are not equally spaced, adjust the position of the ybar by loosening the two
setscrews located in each paddle control frame arm, then sliding the flybar from side to side until
they are.
• Conrm that both ybar paddle control frame arms and rods are parallel to one another. It may be
necessary to loosen the four screws that hold the paddle control frame assembly together in order to
adjust the position of each part.
• Be certain that both ybar paddles are parallel to the ybar paddle control frame arms. If they are
not, loosen the setscrews in the flybar paddle mounts/adapters and twist the paddles until they are
properly aligned and parallel with the paddle control frame arms.
• I f you have made certain that both ybar paddles are parallel to the paddle control frame arms, they
should now be parallel to one another. If they are not, take your time making adjustments in order
to ensure that both flybar paddles are positioned parallel to one another and the paddle control
frame arms.
• Once you have properly positioned and aligned the ybar paddle control frame parts and the ybar
paddles following the tips above, be certain that all screws and setscrews are firmly secured.

Head Dampening Shims and Tuning Cyclic Response
The rotor head (main rotor blade) dampening of your Blade 400 3D model can be adjusted in order to
tune the cyclic response and stability of your model. In general, stiffer dampening will result in quicker
cyclic response with a slight reduction in stability (when compared to softer/less-stiff dampening). The
dampening of your Blade 400 3D model has been set to provide a good balance of cyclic response
and stability right out of the box, and we suggest that you make your first flights with this amount of
dampening before making any changes.
If, after the first few flights, you would prefer to have even quicker and more aggressive cyclic
response, you can stiffen the rotor head dampening by adding shims (in addition to the shims that
were factory-installed) between the O-Ring (025) and Step Washer (020) on each side of the Head
Block/Rotor Housing (see the “Exploded View Parts Listing” and “Exploded View Drawing” pages for
reference). Head Dampening Shims are available separately in packs of eight (EFLH1144), however,
you should add only one shim per side at a time before making each subsequent test flight, until you
find the dampening at which you prefer the cyclic response (and stability) most.
Note: You must always install an equal number of shims on each side of the Head Block/Rotor
Housing.
Note: If you install too many shims, and the dampening becomes too stiff, the helicopter can
wobble and shake in flight. Take care when making test flights after adding shims to prevent
crashing the model as a result of a wobble or shake. Typically, we find that adding an additional
1–2 shims per side with the stock power system works well for more aggressive pilots and 3D
flying. Adding too many additional shims per side can cause the model to wobble and shake.
Again, exercise extreme care when test flying the model after adding any number of shims.
Other options for tuning the cyclic response of your model include adjusting the aileron and elevator
Swashplate Mixing (SWASH MIX), Dual Rate (D/R) and Exponential (EXPO) values in the transmitter
(please see the manual for the DX6i for more information), as well as the installation of different length
flybars and different weight flybar paddles (please see your favorite retailer or visit our web site for
more information).
Recommended Maintenance
Routine maintenance is necessary to keep your Blade 400 3D in optimal and safe flying condition.
Some of the most important things to check routinely include:
• Ball Links
Before each flying session, check to see that the plastic ball link ends are secure, but not tight
(binding), on the linkage/control balls. The plastic ball links can wear over time, and if they become
too loose on the control balls, they can separate from the ball in flight and cause a crash. Be sure to
replace any worn ball links before they fail.
Also, any ball links that are tight (binding) on the linkage/control balls can be loosened by carefully
squeezing the sides of the link with a pair of pliers. However, exercise extreme care when “sizing”
the ball links as it is possible to loosen them too much for safe use.
• Bearings
The one-way bearing in the main drive gear should be cleaned using isopropyl alcohol or electric
motor spray, then lubed with lightweight oil, approximately every 80 to 100 flights. All other
bearings typically exhibit very long life and normally only need to be replaced if they ever become
notchy (sticky in places when turning) or draggy.
• Oiling
It’s important to apply a small amount of lightweight oil (like TRI4026) to any areas where a bushing
may ride on a shaft, especially after replacing any of the parts with new ones after a crash. Some
areas to oil include where the washout base bushing and swashplate control ball ride on the main
shaft, and where the tail rotor control pitch slider bushing rides on the tail rotor shaft.
• O-Ring Head Dampeners
The O-ring dampeners in the head block will periodically wear and lose their elasticity. Worn
O-rings can cause main rotor blade tracking problems as well as stability and control response
issues. If you begin having trouble with the blades going in and out of track during flight, or if the
helicopter feels loose and “mushy” during flight, it is likely time to replace the O-ring dampeners.
The O-ring dampeners can wear out in approximately 30 to 60 flights depending on how the model
is flown.
Also, when replacing the O-ring dampeners, it’s important to lubricate them with grease or
petroleum jelly to prevent friction.
• Tail Rotor Drive Belt
It’s typical for the tail drive belt to stretch slightly over the first few flights. When new, frequently
check and adjust the belt tension as required. After approximately 20 to 40 ights, the belt elasticity
will stabilize, requiring little to no additional tension adjustment.
GENERAL
1) I will not fly my model aircraft in sanctioned events, air shows or model flying demonstrations until it has been proven to be airworthy by
having been previously, successfully flight tested.
2) I will not fly my model higher than approximately 400 feet within 3 miles of an airport without notifying the airport operator. I will give
right-of-way and avoid flying in the proximity of full-scale aircraft. Where necessary, an observer shall be utilized to supervise flying to
avoid having models fly in the proximity of full-scale aircraft.
3) Where established, I will abide by the safety rules for the flying site I use, and I will not willfully or deliberately fly my models in a careless,
reckless and/or dangerous manner.
4) The maximum takeoff weight of a model is 55 pounds, except models flown under Experimental Aircraft rules.
5) I will not fly my model unless it is identified with my name and address or AMA number on or in the model. (This does not apply to models
while being flown indoors.)
6) I will not operate models with metal-bladed propellers or with gaseous boosts, in which gases other than air enter their internal combustion
engine(s); nor will I operate models with extremely hazardous fuels such as those containing tetranitromethane or hydrazine.
RADIO CONTROL
1) I will have completed a successful radio equipment ground range check before the first flight of a new or repaired model.
2) I will not fly my model aircraft in the presence of spectators until I become a qualified flier, unless assisted by an experienced helper.
3) At all flying sites a straight or curved line(s) must be established in front of which all flying takes place with the other side for spectators.
Only personnel involved with flying the aircraft are allowed at or in front of the flight line. Intentional flying behind the flight line is
prohibited.
4) I will operate my model using only radio control frequencies currently allowed by the Federal Communications Commission. (Only
properly licensed Amateurs are authorized to operate equipment on Amateur Band frequencies.)
5) Flying sites separated by three miles or more are considered safe from site-to site interference, even when both sites use the same
frequencies. Any circumstances under three miles separation require a frequency management arrangement, which may be either an
allocation of specific frequencies for each site or testing to determine that freedom from interference exists. Allocation plans or interference
test reports shall be signed by the parties involved and provided to AMA Headquarters. Documents of agreement and reports may exist
between (1) two or more AMA Chartered Clubs, (2) AMA clubs and individual AMA members not associated with AMA Clubs, or (3) two
or more individual AMA members.
6) For Combat, distance between combat engagement line and spectator line will be 500 feet per cubic inch of engine displacement.
(Example: .40 engine = 200 feet.); electric motors will be based on equivalent combustion engine size. Additional safety requirements will
be per the RC Combat section of the current Competition Regulations.
7) At air shows or model flying demonstrations, a single straight line must be established, one side of which is for flying, with the other side
for spectators.
8) With the exception of events flown under AMA Competition rules, after launch, except for pilots or helpers being used, no powered model
may be flown closer than 25 feet to any person.
9) Under no circumstances may a pilot or other person touch a powered model in flight.
