blades whenever the battery is connected.
●Keep loose clothing, shirt sleeves, ties, scarfs, long hair or loose objects
such as pencils or screwdrivers that may fall out of shirt or jacket pockets
4
away from the rotors. The spinning blades of a model of this type can
cause serious injury.
●When choosing a fl ying site stay clear of buildings, trees and power lines.
AVOID fl ying in or near crowded areas.
●DO NOT fl y close to people or pets. Maintain a safe distance from the
quadcopter.
●Do not alter or modify the model. Doing so may result in an unsafe or un-
fl yable model.
●When and if repairs are necessary you must correctly install all components
so that the model operates properly on the ground and in the air. Please
check the operation of the model before every fl ight to insure that all
equipment is operating and that the model has remained structurally sound.
●Please allow a 10 minute cool down period after each fl ight so the motor
controller and motors can cool down. Failure to do so may cause loss of
control due to the controller overheating and shutting down.
●Inspect the rotor blades before each fl ight for nicks. If any damage is found
or if the blades have been damaged, replace the blades before fl ying the
model again.
●After a crash you must inspect all plastic parts on the quadcopter for
damage before attempting to fl y the model again.

BATTERY CHARGING
BATTERY CHARGING
●WARNING!! The charger supplied with the Heli-Max 1Si
Quadcopter contains protective circuitry. If you experience any
difficulties while charging the battery, please disconnect the
battery from the charger and unplug the charger from the power
source. Allow the battery and charger to rest for two hours as this will allow
the charge protection circuit to reset. If this issue re-occurs during normal
use, please contact technical support for further assistance.
❏ Plug the flight battery into the end
of the USB charger.
❏ Plug charger into a USB port. A
steady red light will glow letting you
know the battery is charging. The light
will flash slowly when the charge is
complete. Remove the battery from
the charger. Under normal operating
conditions, the battery may take up to
60 minutes to recharge. Never leave
the battery attached to the charger
after charging is complete.
NOTE: A fast flash indicates a charge error. This is usually an indication that
your battery is defective and should be replaced.
6
Transmitter Setup
❏ Turn the Transmitter on and make
sure that there is a blue light behind
the Heli-Max panel at the top of the
transmitter. The LCD screen should
be on, with a throttle position indicator
and other information.
❏ Install 4 AA batteries in the
transmitter by removing the
battery cover from the back of
the transmitter. Double-check the
polarity of each battery before
replacing the battery cover.
❏ Make sure the electronic trim
indicators on the display are centered.
®
TRANSMITTER CONTROLS
TRANSMITTER CONTROLS
All controls are described with the tail pointing directly toward you. This is
the best way to fly in the beginning since it keeps the control inputs oriented
the same direction.

INSTALLING THE BLADE GUARDS
INSTALLING THE BLADE GUARDS
Installing the optional rotor blade guards is recommended. Besides protecting
the rotor blades from damage, these parts can also allow the 1Si to continue
to fl y if it brushes up against a wall or other solid object.
8
❏ Secure the guard to the frame with
the included screw.
®
FLYING YOUR 1Si QUADCOPTER
FLYING YOUR 1Si QUADCOPTER
Electric motors are very dangerous. Do not work on the model
while the flight battery is plugged in as interference may cause
the main rotor blades to spin, possibly causing injury.
❏ Slide the guard over the motor and
position the hole for the mounting
screw over the dimple on the top of
the arm.
Turn on the transmitter and lay it down
so the antenna is pointed at the LED
on the back of the 1Si as shown in the
photo. Connect the flight battery to
the quadcopter. Do not move the 1Si
or the transmitter until the LED stops
flashing and is steady. This procedure
will help the 1Si to maintain the correct
orientation while in flight or returning
to home position.
NOTE: The 1Si will be “ON” at this point. Your quadcopter has a safe start
feature built in that prevents the motor from activating unless the throttle
stick has been lowered to the lowest position. If the motors won’t run,
please make sure the throttle stick is all the way down and the throttle
trim is at or below center. Wait a couple of seconds and try advancing the
throttle again.
Takeoff
Advance the throttle until the model is at least a foot off the ground and out
of ground effect. If flying outdoors it’s important to stick to light winds. If you
plan to take off and land in grass, place a rubber mat or pad down on the
grass so the small rotating parts don’t get hung up in the grass.
9
Hovering
Once the quad is in the air simply try to keep it in one spot. This will take
some practice. Remember that even a light breeze will have an effect on the
stability of the quad.
Landing
Level the quad into a steady hover and slowly decrease power until it lands.
You might notice as the Quadcopter is ready to touch down it moves around
a little. This is normal as the Quadcopter enters ground effect.
®
BASIC MANEUVERS
BASIC MANEUVERS
Once you are comfortable with hovering in one place start working on
orientations. By this we mean, hover the Quadcopter in all positions, nose
to the right, nose to the left and the nose pointing at you (nose-in). Getting
good at this fundamental discipline will allow you to progress much faster
in some of the more advanced flying maneuvers.
Slow Pirouettes
Move the left stick (left or right) you can rotate the Quadcopter around 360°,
which is called a pirouette.
Forward Flight
Now it’s time to work into basic forward flight. Just take the basic hovering
maneuvers listed above and slowly fly out farther and faster and always
bring the Quadcopter back after one pass. Practice controlled slow flight in
close as well. The more time you spend practicing here, the easier things
will be later on.
®
POST-FLIGHT PROCEDURES
POST-FLIGHT PROCEDURES
Before turning off the transmitter, make sure that all the trim indicators
on the transmitter are centered. If you fi nd that the model is consistently
drifting in one direction, the sensors on the 1Si may need to be re-calibrated
(see Troubleshooting).
Remove the battery from the 1Si. Allow it cool to room temperature and
recharge it. Do not leave the battery connected to the 1Si after the fl ight is
completed.
10
If the model is to be stored for a long time period, please remove the batteries
from the transmitter to avoid damage to the contacts. If storing the model for
several weeks, the batteries for the quadcopter should be charged to 50%
of a full charge and checked after 3 to 4 months.
®
FLIGHT MODE OPTIONS
FLIGHT MODE OPTIONS
Dual Rate
The TX465 transmitter has a dual rate
function. This feature toggles between
a fl ight mode that reduces the model’s
range of motion to make the 1Si easer
to fl y and one that allows the full range
of motion so the 1Si can fl y in a more
aggressive manner. To toggle between
these two fl ight modes, press down
on the right control stick and release
it. When the transmitter is in low rates, the ellipse in the lower center of the
LCD screen will show a half ellipse and emit a single low pitch single beep.
For high rates, the ellipse will be complete and the transmitter will emit a
single high pitch beep.
Flight Control Sensitivity
You can also make the transmitter for the 1Si more or less sensitive by
changing the control setting. To do this, press and hold the right stick down.
When the transmitter starts to beep continuously, move the throttle up or
down to adjust the sensitivity percentage which will be indicated on the LCD
screen. A higher value will make the controls more sensitive. When you have
the desired setting, release the right stick and return the throttle to 0%. We
have found that 30% is good all-around setting. Warning: If this value gets
bumped to 0 your quadcopter will respond very slowly to any right stick input.
Beginner/Expert Mode
When the 1si is turned on it will be in Beginner Mode. In this mode, the
control board will apply “Braking” to slow the 1Si and bring the model to a
hover when the right sticks are released. The quad will be very smooth and
stable in this mode.
Press the “F Mode” button on the upper right corner of the transmitter to
enter the Expert Mode. The LED on the back of the 1Si will fl ash twice, stay
off for a second, fl ash twice again, and then remain on. When the quadcopter
is in this mode, the accelerometers are disabled and the 1Si will not slow
down when the right stick is centered. This mode also will allow the 1Si to
fl y more aggressively.
11
To return to the normal fl ight mode, press the “F Mode” button again. The
rear LED will fl ash twice, stay on for a second, fl ash twice again, and then
remain steady. This sequence indicates that the accelerometers and the
Braking function are active again.
Actual Direction Control
When the “ICM” button on the upper left corner of the transmitter is pressed
for at least 3 seconds, the 1Si will enter the “Actual Direction Control” flight
mode and the LED on the back of quadcopter will flash slowly. In this mode,
the 1Si will use the pilot’s position as a reference point for any signal received
from the right stick on the transmitter. Moving stick forward or backward
will move the quadcopter farther or close to the pilot. The direction that the
front of the 1Si is facing will not have any effect while in this mode. The
antenna on the transmitter must be pointed at the quadcopter at all times
to help the model maintain its position while in flight.
To exit the “Actual Direction Control” mode, press the ICM button again for
3 seconds. The rear LED will become steady to indicate that it is now in the
normal flight mode.
Adjustment Mode
The 1Si will have to be put in the Adjustment
Mode before any adjustments to the return
speed or the sensors can be performed.
1. Turn on the transmitter and connect the
battery to the quad so it can link. Keep
the antenna pointed at the LED on the
1Si until the linking process is completed.
2. Press down on the right stick and hold
it down until the transmitter starts to beep. Continue to hold down the right
stick until the next step is completed.
3. Press down the left stick 4 times and then release both sticks. Push up on
the elevator trim button once and release it. At the same time, watch the display
for a change on the elevator trim indicator. If the indicator does not move, the
transmitter and 1Si are in the Adjustment Mode. Note: Pressing down on the
left stick at any time will cause the transmitter to exit the Adjustment Mode.
Auto Return
To make the 1Si return to you, press the ICM on the upper left corner of the
transmitter quickly and release it. The rear LED will flash quickly and model
will start to fly toward the transmitter. The pilot can use the throttle to control
the altitude, but any movement with the right stick will cause the model to
return to the normal flight mode. When the model gets close, the pilot should
expect to use the transmitter to slow the 1Si and bring it to a hover. Note:
The transmitter antenna should point at the quadcopter at all times to
help keep the 1Si on course.
12
This procedure should be used if the return speed of the 1Si needs to be
changed.
1. Enter the Adjustment Mode as described earlier.
2. Push the rudder trim button to the left increase the return speed. The
longer the button is held to the left, the LED on the 1Si will fl ash faster
and the tone will increase in pitch to indicate that a higher return speed is
being selected. When the LED remains steady, the highest speed has been
selected. Moving the button to the right will reduce the return speed. The
LED will fl ash slower and the pitch will be lower to indicate the speed that is
being selected. When the LED turns off, the lowest speed has been selected.
3. Press down on the left stick to exit the Adjustment Mode when the desired
speed has been selected.
®
CAMERA OPERATION
CAMERA OPERATION
The camera will be in VIDEO mode when it is fi rst powered up. Press the
VIDEO button to start recording a video. You will see the LED on the side of
the camera fl ash slowly while the video is being captured. To stop recording
and store the video, press the VIDEO button again. The LED will stop fl ashing
to indicate that the camera is ready for use. If the card is removed or the
battery unplugged while the camera is recording, the video will NOT be
saved on the card.
Before the camera can take a photo, it must be in the Picture mode. Press
the PICTURE button one time, to change the mode. The LED on the camera
will remain steady while the camera mode is changed. Press the PICTURE
button to take a photo. You will notice that the LED will fl ash rapidly as the
picture is recorded and stored on the microSD card. When the LED stops
fl ashing, the camera is ready to take another photo. If the Picture button is
pressed while the LED is fl ashing, the camera will not capture another photo.
The VIDEO button must be pressed once to change modes before the camera
will capture a video.
Installing the MicroSD Card
To minimize any chance of data being lost
on the microSD card, do not insert or remove
the card from the camera until the battery
has been unplugged from the quadcopter.
Remove the SD card from the protective
case. Flip the model over and push the card
into the slot on the side of the camera
module. When the card is correctly installed,
it will click. To remove the card, simply press
13
on the card again and the inner spring system will help eject the card. Note:
The card must be in place to capture video or Pictures. The camera has no
internal memory.
Downloading the video and pictures from the camera:
Install the MicroSD card into the reader.
Plug the reader into the USB port of
your computer.
The USB connection will be auto
recognized and the files ready to be
transferred.
At this point you can copy or transfer
your files to your folder structure.

TROUBLESHOOTING
PROBLEM: 1Si does not react to any stick movements.
Solution 1: Make sure that the battery voltage is above 4.0 volts
Solution 2: If the LED on the rear of the model is not steady, unplug the
battery and turn off the transmitter to allow the control board to reset itself.
After about a minute, turn on the transmitter and reconnect the battery.
TROUBLESHOOTING
PROBLEM: Flies with poor power or buzzes.
Solution: One of the props may be bent. Carefully bend it straight.
PROBLEM: You notice that one of the motors spins noticeably slower
or feels tight.
Solution: Replace the motor. This is done by removing all 4 props and
loosening the screws holding the frame together. Remove the top of
the frame and unplug the defective motor wire from the control board.
The LED board can be popped off the alignment posts with a small
screwdriver. The motor will slide out of the frame and the new motor/
LED board can now be installed. A couple of small pieces of tape will
hold the LED board in place.
PROBLEM: The 1SI will not return directly to you in Auto Return mode.
Solution: Calibrate the transmitter and or the control board.

Control Board Sensor Calibration
1. Enter the Adjustment Mode as described on page 12.
2. Press up on the throttle trim button and the rear LED on the 1Si will
start flashing rapidly.
3. When the LED stops flashing, press down on the left stick to exit.
If you still have problems, try the tip on page 17.
Transmitter Calibration
Press on the ICM button while turning on the transmitter. The display will
show a “1” briefly then display a “2”.
Place the transmitter down on its
back with the antenna pointed
away from you. Slowly rotate
the transmitter clockwise three
times, then three times counterclockwise.
Pick the transmitter up by the
sides and rotate it so the antenna
moves toward you. Rotate it three
times, then three more times in the
opposite direction.
Hold the transmitter by the
antenna and bottom with antenna
pointed away from you. Rotate
the transmitter left to right three
times. Rotate it three more times
from right to left.
15
Hold the transmitter by the upper
right corner and lower left corner
so the antenna is pointed 45
degrees to the right. Rotate the
transmitter three times with the
antenna moving toward you, then
three more times in the opposite
direction.
Put the transmitter down with the antenna pointed away from you and
push the ICM button. The display should read “0”.
Press the F Mode button. The display will indicate 90 and the transmitter
should be rotated so the antenna
is at 90 degrees. Each time the
F Mode button is pressed, the
display will increase 90 degrees
and the transmitter should be
rotated to that position before the
button is pressed again. When the
display reads “0”, press the F Mode
button to exit the calibration mode.
This procedure will usually correct problems with the Auto Return or
Actual Direction Control modes. If you continue to have problems, please
try the model in another area. There may be some interference in your
flying location that is affecting the sensors.
