GENERAL NOTES

• Radio controlled models provide pleasurable skill challenges
and opportunity for increasing mastery of piloting.

• Models are hazardous when operated and maintained incor­rectly.

• Always install and operate a radio control system correctly.

• Always pilot a model so the model is kept under control in
all conditions.

• Please seek help from an experienced pilot or your local
hobby store.

• Contact local or regional modeling organizations for guid­ance and instructions about ying in your area.

• When working with a model, always power on transmitter
rst and power off the transmitter last.

• After a model is bound to a transmitter and the model is set
up in the transmitter, always bind the model to the transmit­ter again to establish failsafe settings.

PILOT SAFETY

• Always make sure batteries are fully charged before ying.

• Time ights so you y safely and under control.

• Do a range check of the transmitter and the model before
ying a model.

• Make sure control surfaces correctly respond to transmitter
control before ying.

• Do NOT y a model near spectators, parking areas or any
other area that could result in injury to people or damage to
property.

• Do NOT y during adverse weather conditions. Poor visibility
can cause pilot disorientation and loss of control of a model.
Wind can cause loss of control and damage to a model.
Moisture and ice can damage a model.

• Do NOT point transmitter antenna directly at a model.
The signal coming from the tip of the antenna is weak by
comparison to the signal coming from other parts of the
antenna.

• When a ying model does not respond correctly to controls
(moving erratically or abnormally) land the model and cor­rect the cause of the problem.

DSMX

Spektrum launched the 2.4GHz RC revolution with its DSM2
technology. Since then millions of hobbyists the world over have
come to embrace 2.4 as the way to y. Spektrum leads the way
yet again with DSMX; the world’s rst wideband, frequency-agile

2.4GHz signal protocol.

How Does DSMX Work?

It’s a crowded 2.4GHz world out there and every 2.4GHz system
faces the same challenges. DSMX better equips you for these
challenges by combining the superior data capacity and interfer­ence resistance of a wideband signal (like that used in DSM2)
with the agility of frequency shifts.

Compared to the wideband signal of DSMX, the narrow band
signal of other frequency hopping 2.4 transmitters is more likely
to suffer data loss in the event of on-channel interference. Think
of it as a river vs. a stream. It takes more interference to dam a
river than it does a stream.

As more and more 2.4 transmitters vie for the same number
of available channels, there is more interference and more of a
risk for data loss. By adding the agility of frequency shifts to the
superior interference resistance of a wideband signal, DSMX
is far less likely to suffer signicant data loss from on-channel
interference. The result is quicker connection times and superior
response in even the most crowded 2.4GHz environment.

NOTICE: While DSMX allows you to use more than 40 transmit­ters simultaneously, when using DSM2 receivers, DSMX receiv­ers in DSM2 mode or transmitters in DSM2 mode, do not use
more than 40 transmitters simultaneously.

DSMX Operational Differences

DSMX transmitters and receivers function nearly identically to
Spektrum DSM2 systems. Binding, setting the failsafe, recording
ight log data, as well as general use of the system is no differ­ent than using any current Spektrum system.

Following are the operational differences:

Brownout Detection- Not Available on DSMX Receivers,
DSM2 receivers feature Brownout Detection that ashes the
receiver’s LED if a power interruption occurs. While DSMX
receivers have QuickConnect™ and recover instantly from a
power interruption, the architecture of DSMX prevents Brownout
Detection when operating in DSMX mode.

Flight Log Recording- Fades Higher than DSM2
Note that DSMX hops through the band while DSM2 nds two
quiet channels and remains on those channels. Consequently
because DSMX operates on quiet and noisy channels, it’s com­mon to have more Antenna Fades than when using DSM2, when
used in busy 2.4GHz environments. When taking ight log data
readings, the Frames and Hold Data are important and should be
used a reference while Fades are insignicant due to the nature
of frequency hopping. A 10-minute ight will typically result in
less than 50 Frame Losses and no Holds.

Just How Good is DSMX?

In multiple tests, 100 DSMX systems were operated simultane­ously for extended periods of time. During these tests each of the
100 systems was monitored in ight and on the ground. In every
test not a single case of RF link loss, latency increase or control
degradation was experienced or recorded.

Is DSMX Compatible with DSM2?

Yes. DSMX is fully compatible with all DSM2 hardware. In fact,
many pilots may nd the DSM2 equipment they have now is all
they will ever need. Even if a new DSMX transmitter eventually
comes along that they really want, all the DSM2 receivers they
have now will work with it.

It is important to note, however, that while DSMX is compatible
with DSM2, the only way to experience the full benets of DSMX
in a busy 2.4 environment is by pairing a DSMX transmitter with
a DSMX receiver.

Can DSM2 Transmitters be Upgraded to DSMX?

Yes. DX8 owners can simply download Spektrum AirWare™ v2.0
software from spektrumrc.com and update the rmware using
their SD card. DX6i transmitters manufactured after October
2010 can be upgraded using instructions provided on spektrum­rc.com. All other DX6i DSM2 transmitters can be upgraded for
$75 by sending them to the Horizon Hobby service center. DSM2
receivers and transmitter modules cannot be upgraded to DSMX.

Does DSMX have ModelMatch and ServoSync?

Yes. DSMX will provide you with these and other exclusive Spek­trum advantages you already enjoy with DSM2.

You must bind the receiver to the transmitter before it will operate. Binding is sharing identication codes between the receiver and
the active memory of the transmitter. Once bound, the receiver only connects to the transmitter when the previously bound model
memory is selected. You will need to rebind after the model is set in the transmitter to fully program the model’s failsafe positions. If
another model memory is selected, the receiver will not connect. This feature is called ModelMatch™ and prevents ying a model
using the wrong model memory.

WARNING: Do not pick up the

transmitter by the antenna. Do not
alter or put weight on the antenna. Damage
to antenna parts can decrease transmitter
signal strength, which can result in loss of
model control, injury or property damage.

WING TAIL MIX

Wing Tail Mix function supports Normal, Dual Aileron, V-Tail and
Elevon (Delta) mixing. Refer to your model’s manual for recom­mended settings. See Appendix for information about recom­mended wing type servo installations on scratch built models.

Normal

This normal or default setting for airplanes is 1 servo channel
for aileron, 1 channel for elevator and 1 channel for the rudder.
These common wing and tail functions are enabled when you
set DUALAILE, ELEVON and V-TAIL at INH (inhibit).

Dual Aileron Wing Type Selection

Dual Aileron requires use of a servo for each aileron and sup­ports use of ailerons as aps or spoilers. This function also
supports precise independent adjustment of up and down travel,
and independent sub-trim and differential for each aileron.

V-tail Selection

V-tail combines the elevator and rudder channels for pitch and
yaw control when using a V-tail equipped airplane. This function
also supports precise independent adjustment of up and down
travel, and independent sub-trim and dual rate adjustments for
V-tail control surfaces.

Elevon Wing Type Selection

Elevon (Delta) wing combines aileron and elevator functions for
precise control of roll and pitch.
Note: Delta or Elevon Mixing is for ying-wing airplanes and
uses 2 servos in the wing to control 2 trailing edge-control
surfaces for pitch and roll control.

Elevator stick input causes movement of the surfaces together
for up/down movement and pitch control. Aileron stick control
input causes movement of the surfaces in opposite directions
for roll control. Connect one tail servo to (ELE) and the other tail
servo to (AILE) in the receiver. Use individual functions such as
servo reversing, sub-trims, etc. for each servo to achieve correct
control surface movement. Use sub-trims for separate neutral
adjustments. Use dual rate function so you can independently
adjust elevator-versus-rudder travel.

D/R & EXPO (Dual Rate & Expo)

The Dual Rate and Exponential function supports programming
of 2 control rates. Dual Rates and Expos are available for aileron,
elevator and rudder channels. Changing Dual Rate value affects
maximum control authority and sensitivity of control. Increasing
the rate increases sensitivity of the controls. Changing Expo­nential value affects sensitivity around center (neutral). You can
control Dual and Expo rates by respective D/R switches (aileron,
elevator and rudder) or by one common switch (Aileron D/R, El­evator D/R, Rudder D/R or the Gear switch. See COMBI SWITCH
screen for combining D/R switches to one common switch).
You can adjust dual rate values from 0–100%. Factory default
settings are 100% for switch positions 0 and 1.

Note: Refer to your model’s manual for recommended rate
settings.

Exponential values are adjustable from -100% to +100%. The
factory default setting is 0% or INH (inhibit).

CCPM swashplate servos, AILE (aileron), ELEV (elevator) and
PITC (pitch). Refer to your model’s manual for recommended
settings.

A Input
B Input values (-125 to +125%). (For example, when the

swashplate moves up when the control stick is moved down
and the channel’s swash mix value is positive, make the
channel’s value negative to make the swashplate move
down with the same stick movement. Servo reversing and
swash mix adjustment may be required on some models.)

MIX 1 or MIX 2

Mix 1 and 2 functions mix percentages between 2 channels, or
a channel with itself (THROTTLE cannot be mixed with itself or
as a slave).
You can program mixes so that stick or switch inputs control 2
or more servos.
The rst channel is the master channel; the second is the slave
channel. You can adjust directional mix values (U, D, L and R)
between -125% to +125%.
The mix can either be enabled (ON) all times or assigned to a
switch, enabling and disabling the mix as needed while operat­ing a model. You can also link trim so that adjusting master
channel trim will also adjust slave channel trim.
When a mix is enabled and the assigned input control is moved,
the master channel sends output at the same time the slave
channel sends output.
Output is sent to the model in the direction and to the position
assigned in the Mix screen. Output sent to model will match
assignments in Mix screen.

CAUTION: Before ying a model, always do a check of
channel mix response by viewing channel results on the
Servo MONITOR screen.

Mix Options

Aileron to Rudder: Causes rudder to move when ailerons
move. This helps with airplanes that have adverse movement
of the nose around the center axis (yaw) (right aileron results in
left nose movement (yaw)). When programming aileron to rudder
mix in the same direction, the airplane makes coordinated turns
using ailerons only.
Elevator to Flap: Causes aps (or aperons) to move when
elevator is moved, resulting in tighter looping maneuvers,
or to provide aileron reex for some 3D maneuvers such as
Harriers.
Dual Elevators: Requires Gear to Gear Mix of -100% to -100%
to inhibit (INH) Gear Channel Switch, then Elevator to Gear Mix
of +100% to +100% to activate the Gear channel to work as a
slave to the elevator channel. This makes dual elevator setups
possible.
Rudder to Aileron or Elevator: Eliminates roll and pitch cou­pling (roll and pitch happening at the same time) when rudder is
applied. This is normally used to correct coupling in knife-edge
ight.

MASTER/SLAVE INFORMATION

To operate the DX6i as a master:

• Transmitter batteries fully charged.

• Bind the transmitter to the model.

• Connect the trainer cord (SPM6805) to the back of the
transmitter.

• Make sure the slave transmitter batteries are fully charged.

• Make sure the slave transmitter is powered off; the slave
transmitter receives power when you connect the trainer
cord. At this point, the slave will not transmit a signal to the
model.

• Move and hold the master transmitter’s trainer switch to
give model control to a slave transmitter.

• The trainer switch is on the back left of the transmitter
(Mode 2, used in USA or on the right side on Mode 1 trans­mitters).

• Release the trainer switch to give model control to the
master transmitter.

SPEKTRUM DX6i • RADIO INSTRUCTION MANUAL

FAILSAFE

When you bind your transmitter to a Spektrum receiver, you
program the receiver with Failsafe defaults. If the receiver loses
connection to the transmitter, the receiver goes to Failsafe,
operating in default control positions programmed at binding
(until connection is restored to the transmitter).

NOTICE: Failsafe varies among receivers. Before using a
receiver, read receiver’s instructions for Failsafe instructions and
information.

Failsafe

SmartSafe Failsafe, Hold Last Command Failsafe and
Pre-Connect Failsafe are set at binding.
These Failsafes can provide these benets:

• When only the receiver is powered on (no transmitter signal
is present), speed controller (ESC) does not arm and electric
motor is not powered on.

• If connection is lost, SmartSafe moves throttle to position set
at binding so electric motors power off or gas/glow engines
decrease to idle.

• If connection is lost, all channels (except for throttle channel)
hold the last command received from the transmitter. For

EN

example, if the model is turning when the control connection
is lost, the model will keep turning until connection to the
transmitter returns.

CAUTION: Restrain model on the ground while binding

the receiver to a transmitter (which is setting Failsafe)
or doing a test of Failsafe. When Failsafe is not set correctly, a
model’s throttle may go to middle or full throttle.

How To Program

1. Keep bind plug in receiver bind port during binding.

2. Remove bind plug only after receiver connects to transmitter.

How To Test

Note: This test applies only to receivers with these features.

1. Power on receiver and make sure model responds with
throttle going to lowest setting.

2. Power on transmitter and wait for connection to the receiver.

3. Increase transmitter throttle then power off the transmitter.

4. Make sure model throttle goes to low setting and that all
controls hold the last command.

NOTICE: Before ying, ALWAYS make sure the transmitter and
receiver are bound for the correct failsafe.

Preset Failsafe

Note: Not all Spektrum receivers have Preset Failsafe.

Refer to your receiver’s instructions for Failsafe instructions
and information.
Preset Failsafe is useful for sailplanes. If there is a loss of signal,
spoilers can deploy to bring the model down, preventing yaway.

CAUTION: Restrain model on the ground while binding

the receiver to a transmitter (which is setting Failsafe)
or doing a test of Failsafe. When Failsafe is not set correctly, a
model’s throttle may go to middle or full throttle.

How To Program

1. Install the bind plug in the receiver bind port.

2. Power on the receiver.

3. Receiver LED will blink, indicating the receiver is
in bind mode.

4. Remove the bind plug from the receiver.

5. Receiver LED will continue blinking.

Where supplied with the transmitter, install the primary receiver
in your model. Put the primary receiver in protective foam and
install the receiver in the model using rubber bands or hook­and-loop straps. Use thick double-sided foam tape to install the
primary receiver in electric models or helicopters.

Install the remote receiver apart from the primary receiver to
improve RF path diversity (a receiver’s ability to detect a signal in

6. Move transmitter control sticks and switches to desired
failsafe positions (throttle to low position).

7. Move and hold transmitter bind switch in bind position.

8. Power on the transmitter.

9. The receiver and transmitter connect in less
than 15 seconds.

10. When the receiver connects to the transmitter, the receiver
LED will show a solid light, indicating bind.

11. Release the transmitter bind switch.

12. Remove bind plug from the receiver.

How To Test

1. Power on transmitter and wait 5 seconds.

2. Power on receiver.

3. After receiver connects to transmitter, increase transmitter
throttle then power off the transmitter.

4. Make sure model throttle goes to low setting and that all
controls go to preset positions.

Note: Some analog servos may coast a small amount, even
without a signal. This is normal.

all conditions). Each receiver needs a different RF environment,
especially in aircraft containing conductive materials (such as
large gas engines, carbon ber, pipes, etc.) which block a radio
signal.

Install the remote receiver in the model using servo tape. Keep
primary and remote receiver antennas at least 2 inches (51mm)
apart. Move antennas so the wires are perpendicular to each
other, although this is not critical.

19SPEKTRUM DX6i • RADIO INSTRUCTION MANUAL

EN

In airplanes, install the main receiver in the servo tray in the cen­ter of the fuselage. Install the remote receiver in the servo tray
by the side of the fuselage or in the turtle deck (space behind
the canopy and in front of the vertical stabilizer).

In helicopters, install receivers in the servo tray, where there
is usually sufcient room for receiver separation. Where there
is not sufcient room, install a receiver on an external receiver
mount made of clear plastic.
Note: The DSMX DX6i is compatible with all current Spektrum
DSM2 and DSMX aircraft receivers, but NOT compatible with the
original DSM AR6000 receiver.

CAUTION: When using the DSMX DX6i with parkyer

receivers (the AR6100, AR6110, and AR6115), it’s
imperative that these receivers only be own in parkyer-type
aircraft (small electric airplanes or mini and micro helicopters).
Flying receivers designed for parkyers in larger aircraft could
cause loss of connection.

Servo Installation

Due to vibration, install servos using rubber grommets and
bushings in gas- and glow-powered models.

Do not over-tighten mounting screws.
Install servos using servo tape and glue in electric and non­powered aircraft. See model instructions for installing servo(s)
in your model.

Servo Precautions

Do NOT lubricate servo gears or motors.

Do NOT overload retract servos during retracted or extended
conditions.

Always make sure servo arms and linkages can move freely over
the whole path of their intended travel. A blocked servo linkage
or servo arm can cause a servo to draw too much current so a
battery charge is quickly drained.

Always correct control surface vibration, such as “buzz” or “ut­ter.” Vibration can destroy feedback potentiometers in servos.

Always install servos using rubber grommets and brass eyelets.
Do NOT over-tighten servo mounting screws. Doing so inhibits
the screws from dampening vibration.

Always make sure a servo arm is fully attached to the servo. Use
only supplied servo arm screws. Use of other sizes of screws or
screws from other manufacturers can result in damage to the
servo.

Always remove and discard “yellowed” or otherwise discolored
servo arms. Discoloration shows material may be brittle and can
break at any time, possibly causing an aircraft crash.

Always make sure model screws and linkages are tight. Vibration
loosens screws and linkages so that damage can result.

Power System Requirements

Set up and operate a model so power to the receiver is NEVER
interrupted while ying. This is especially critical on giant-scale
models that use several high-torque or high-current servos.
Power systems unable to provide minimum receiver voltage
in ight are the number-one cause of in-ight failures. Some

components that cause a receiver to have too little power supply
include:

• Receiver battery (number of cells, capacity, cell type, state of
charge)

• Switch harness

• Battery leads

• Regulator (where used),

• Power bus (where used)

While a Spektrum receiver’s minimum operational voltage is

3.5 volts, test your model to a minimum acceptable voltage of

4.8 volts during ground testing. This battery charge capacity
compensates for discharge during ight or for ight loads larger
than ground test loads.

CAUTION: We recommend that you DO NOT y a model
with battery charges at less than 5.3-volts.

Recommended Power System Guidelines

1. When setting up a large or complex aircraft with multiple
high-torque servos, use a current and voltmeter (Hangar 9
HAN172). Connect the volt-meter in an open channel port in
the receiver. With the system powered on, load the control
surfaces (apply pressure with your hand) while monitoring
voltage at the receiver. The voltage must remain above 4.8
volts when all servos are heavily loaded.

Note: The optional Spektrum Flight Log (SPM9540) has a
built-in voltmeter for doing this test. The Flight Log is compat­ible with Spektrum receivers SPMAR9010, SPMAR9110 and
SPMAR7010 (AR7000).

2. With the current meter connected in line with the receiver
battery lead, load control surfaces (apply pressure with your
hand) while monitoring the current. The maximum continu­ous current for a single heavy-duty servo/battery lead must
be no more than 3 amps, while short-duration current spikes
of up to 5 amps are acceptable. When your system draws
more than 3 amps continuous or 5 amps for short durations,
use multiple packs with multiple switches and multiple leads
connected to the receiver.

Note: The Flight Log cannot measure current draw (amps).
When the Flight Log is used to measure voltage, also use the
HAN172 current meter to measure the current draw of the
servos.

3. When using a voltage regulator, do the tests for 5 minutes or
more. Current passing through a regulator generates heat.
Resistance increases, causing heat to increase (thermal
runaway). While a regulator may provide adequate power for
a short time, test for longer to make sure it can keep voltage
consistent at signicant power levels.

4. Use multiple battery packs with multiple switch harnesses
on large aircraft or complex models (for example, airplanes
35% and larger or jets). In many cases, commercially avail­able power boxes or busses must be used. No matter what
power systems are used, always do a test (described above)
to make sure the receiver is supplied with 4.8 volts or more
under all conditions.

5. Peak detection fast chargers may show a false full charge on
NiMH batteries. We recommend use of a charger that shows
an NiMH battery’s total charge capacity. Make sure NiMH
battery packs are fully charged when using any charger.

AMA NATIONAL MODEL AIRCRAFT SAFETY CODE

Effective January 1, 2010

GENERAL

A model aircraft shall be dened as a non-human-carrying
aircraft capable of sustained ight in the atmosphere. It may not
exceed limitations established in this code and is intended to be
used exclusively for sport, recreation, and/or competition.

1. I will not willfully y my model aircraft in a careless or reck­less manner, and will abide by this Safety Code and any
additional rules specic to ying sites.

2. I will yield the right-of-way to man-carrying aircraft and
will see and avoid all aircraft, utilizing a spotter when ap­propriate. (See AMA Document #540-D on See and Avoid
Guidance.)

3. I will not y my model aircraft higher than approximately 400
feet above ground level, when within three (3) miles of an
airport without notifying the airport operator.

4. The maximum takeoff weight of a model aircraft, including
fuel, is 55 pounds, except for those own under the AMA
Experimental Aircraft Rules.

5. I will not y my model aircraft in sanctioned events, air
shows, or model demonstrations unless I have previously
proven that my aircraft, control system, and piloting skills are
adequate by successfully executing all maneuvers intended
or anticipated in the specic event. If I am not a procient
pilot, I will not y in these events unless assisted by an
experienced pilot.

6. I will not y my model aircraft unless it is identied with my
name and address, or AMA number, inside or afxed to the
outside of the model aircraft. This does not apply to model
aircraft own indoors.

7. I will not operate model aircraft with metal-blade propellers.

8. I will not operate model aircraft carrying pyrotechnic devices
which explode or burn, or any device, which propels a
projectile of any kind. Exceptions include Free Flight fuses
or devices that burn producing smoke and are securely at­tached to the model aircraft during ight. Rocket motors up
to a G-series size may be used, provided they remain rmly
attached to the model aircraft during ight. Model rockets
may be own in accordance with the National Model Rock­etry Safety Code; however, they may not be launched from
model aircraft. Ofcially designated AMA Air Show Teams
(AST) are authorized to use devices and practices as dened
within the Team AMA Program Document.

9. I will not operate my model aircraft while under the inuence
of alcohol or while using any drug which could adversely
affect my ability to safely control the model.

10. When and where required by rule, helmets must be
properly worn and fastened. They must be OSHA, DOT, ANSI,
SNELL or NOCSAE approved or comply with comparable
standards.

Please see your local or regional modeling association’s
guidelines for proper, safe operation of your model aircraft.

FCC INFORMATION

This device complies with part 15 of the FCC rules. Operation
is subject to the following two conditions: (1) This device may
not cause harmful interference, and (2) this device must accept
any interference received, including interference that may cause
undesired operation.

CAUTION: Changes or modications not expressly

approved by the party responsible for compliance could
void the user’s authority to operate the equipment.
This product contains a radio transmitter with wireless technol­ogy which has been tested and found to be compliant with
the applicable regulations governing a radio transmitter in the

2.400GHz to 2.4835GHz frequency range.

FAA INFORMATION

Antenna Separation Distance

When operating your Spektrum transmitter, please be sure to
maintain a separation distance of at least 5 cm between your
body (excluding ngers, hands, wrists, ankles and feet) and the
antenna to meet RF exposure safety requirements as determined
by FCC regulations.
The illustrations below show the approximate 5 cm RF exposure
area and typical hand placement when operating your Spektrum
transmitter.

Purpose

This advisory outlines safety standards for operations of
model aircraft. We encourage voluntary compliance with
these standards.

Background

Attention has been drawn to the increase in model aircraft op­eration. There is a need for added caution when operating free
ight and radio controlled craft in order to avoid creating a noise
nuisance or a potential hazard to full-scale aircraft and persons

and/or property on the surface.

Operating Standards

Modelers generally are concerned with safety and exercise good
judgment when ying model aircraft. However, in the interest of
safer skies, we encourage operators of radio controlled and free

ight models to comply with the following standards:

a. Exercise vigilance in locating full-scale aircraft (get help if

possible) so as not to create a collision hazard.

b. Select an operating site at sufcient distance from

populated areas so you do not create a noise problem or a
potential hazard.

c. Do not y higher than 400 feet above the surface.

Servo Control

For a delta wing or elevon wing setting, check the control throw
directions.
Begin by checking the aileron direction. With right aileron stick
movement, the right elevon should move up and the left elevon
should move down.
If the right elevon moves in the incorrect direction, reverse the
channel in the transmitter that the right elevon is plugged into.
If the left elevon moves in the incorrect direction, reverse that
channel in the transmitter.
Once both elevons move in the correct direction with aileron
stick movement, check the elevator direction. With up elevator,
both elevons should go up and vice versa.
If the elevator direction is incorrect, switch the servo channels in
the receiver.

The possible servo reversing options for a delta wing model are
