INTRODUCTION
Thank you for purchasing the Heli-Max AXE™CP V3 RTF
Helicopter. We are certain you will get many hours of
enjoyment out of this model. If you should have any questions
or concerns please feel free to contact us at:
[email protected].
For the latest technical updates or manual corrections
to the AXE CP V3 RTF visit the Heli-Max web site at
www.helimax-rc.com. Open the “Helicopters” link, and
then select the AXE CP V3 RTF. If there is new technical
information or changes to this model a “tech notice” box will
appear in the upper left corner of the page.
CAUTION: Be aware that the AXE CP V3 RTF operates
on the same frequency band as larger R/C models. If flying
your AXE CP V3 RTF within five miles of an R/C site, there
is a real possibility that you could be operating your model
on the same frequency (channel) as another R/C pilot.
If this happens, a crash will result–with the person flying
the more expensive model suffering the greater loss (and
having greater potential for property damage or injury).
The best thing to do is to join an R/C club and fly at the
site where frequency control measures will be in effect. If
you insist on flying elsewhere, always be aware of your
proximity to R/C flying sites.
AMA
We urge you to join the AMA (Academy of Model Aeronautics)
and a local R/C club.The AMA is the governing body of model
aviation and membership is required to fly at AMA clubs.
Though joining the AMA provides many benefits, one of the
primary reasons to join is liability protection. Coverage is not
limited to flying at contests or on the club field. It even applies
to flying at public demonstrations and air shows. Failure to
comply with the Safety Code (excerpts printed in the back of
the manual) may endanger insurance coverage. Additionally,
training programs and instructors are available at AMA club
sites to help you get started the right way. There are over
2,500 AMA chartered clubs across the country. Contact the
AMA at the address or toll-free phone number below.

IMPORTANT!!! Two of the most important things you can do
to preserve the radio controlled aircraft hobby are to avoid
flying near full-scale aircraft and avoid flying near or over
groups of people.
SAFETY PRECAUTIONS
Failure to follow these safety precautions may result in
severe injury to yourself and others.
• Keep your face and body as well as all spectators away
from the plane of rotation of the rotors whenever the battery
is connected.
• Keep these items away from the rotors: 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 into the rotors.
• The spinning blades of a model helicopter can cause
serious injury. When choosing a flying site for your AXE
CP V3 RTF, stay clear of buildings, trees and power lines.
AVOID flying in or near crowded areas. DO NOT fly close to
people, children or pets. Maintain a safe pilot-to-helicopter
distance while flying.
1. Your AXE CP V3 RTF should not be considered a toy, but
rather a sophisticated, working model that functions very
much like a full-size helicopter. Because of its performance
capabilities, the AXE CP V3 RTF, if not assembled and
operated correctly, could possibly cause injury to yourself or
spectators and damage to property.

2.You must assemble the model according to the instructions.
Do not alter or modify the model, as doing so may result in
an unsafe or unflyable model. In a few cases the instructions
may differ slightly from the photos. In those instances the
written instructions should be considered as correct.
3. You must correctly install all R/C and other components
so that the model operates correctly on the ground and in
the air.
4. You must check the operation of the model before every
flight to insure that all equipment is operating and that the
model has remained structurally sound. Be sure to check
linkages or other connectors often and replace them if they
show any signs of wear or fatigue.
5. If you are not an experienced pilot or have not flown
this type of model before, we recommend that you get the
assistance of an experienced pilot in your R/C club for
your first flights. If you’re not a member of a club, your local
hobby shop has information about clubs in your area whose
membership includes experienced pilots.
We, as the manufacturer, provide you with a top quality,
thoroughly tested helicopter and instructions, but
ultimately the quality and flyability of your finished model
depends on how you build it; therefore, we cannot in any
way guarantee the performance of your completed model,
and no representations are expressed or implied as to the
performance or safety of your completed model.
Remember:Take your time and follow the instructions to
build a safe and enjoyable model.
ITEMS REQUIRED
❏Eight “AA” Alkaline Batteries for the Transmitter

ASSEMBLY INSTRUCTIONS
INSTALL BATTERIES IN THE TRANSMITTER
❏1.Remove the battery cover from the back of the transmitter.
Remove the battery box and install eight “AA” batteries in the
transmitter.Check the polarity of each battery before replacing
the battery cover.
❏2.Turn on the transmitter using the power switch as shown
above. Check the LEDs on the front of the transmitter. Only
the Green LED should be on. If the Red LED is on or flashing,
then the batteries need replacing.
CHARGING THE FLIGHT BATTERY
IMPORTANT!! Always remove the LiPo battery pack
from the helicopter and charge the battery in a location
that is fireproof. Never leave the battery unattended
while being charged! If the battery becomes hot, starts
to smoke or begins to swell immediately disconnect the
battery from the charger and carefully move the battery
to a fireproof location!
❏1. Connect the input power plug from the AC Wall adapter
to the charger. The power light should now be bright red and
the charger indicator light should be off.
❏2. Always use the charge and balance connector on the
battery when charging. Do not use the discharge connector
to charge the battery!
❏3. Connect the battery to the balance connector on the
charger. The charge indicator light will turn to red, indicating

6
6
6
that the battery is being charged. If the charger indicator
light turns to green immediately, then the battery is already
fully charged.
❏4. When the battery is fully charged, the charge indicator
light will turn GREEN. Remove the battery from the charger at
this time and disconnect the charger from its power source.
❏5. Charging time depends on the amount of charge
remaining in the battery.The charge process may take as long
as 2 hours and 30 minutes with a fully discharged battery.
INSTALL THE BATTERY
❏1. Remove the lower canopy retainers from the lower
canopy mount.
❏2. Remove the canopy by sliding the canopy grommets
off of the carbon rods. Slide the battery into the front of the
battery tray as shown above. Use three rubber bands to hold
the battery into the tray.
INSTALL MAIN ROTOR BLADES
❏Please make note of the 2mm nut used on the bottom of
each blade grip. When removing the blade bolt, press upward
on the nut to ensure it remains in the grip. Remove the blade
grip bolts using the 1.5mm hex wrench. Slide a blade into
the blade grip and re-install the 2 x 12mm socket head cap
screw. Repeat for the other blade.
BLADE TENSION TEST
❏To test the blade tension, hold the helicopter up sideways.
The blades should support themselves until the helicopter
is shaken slightly; then they will fall as shown in the picture
above. The blades should be fairly loose but it is critical that
both blades are the same tension.

7
ASSEMBLE TRAINING GEAR
❏1. Snap the four plastic fittings onto the landing gear
as shown. Slide the carbon rods through the underside of
the fittings.
❏2. Cut the supplied silicone tubing into eight 1/8" [3mm]
pieces. Please keep in mind that carbon rods are dangerous
to handle and splinter easily. Using pliers, carefully slide
the silicone tubing onto the carbon rod approximately 4"
[102mm]. Now install a foam ball followed by a washer. Using
pliers, install the last piece of fuel tubing. Repeat this step for
the other three balls.
GET THE MODEL READY TO FLY
ELECTRIC MOTOR WARNING
Electric-powered models are very dangerous. Please remove
the pinion gear or unplug the motor while working on the
model. If your helicopter uses an electric tail motor, make
sure it is unplugged as well.
TURNING THE MODEL ON
Always turn the Transmitter on first and ensure the idle up
switch is off. With the AXE CP V3 RTF sitting still, plug the
battery into the ESC. The AXE CP V3 RTF must sit still for
10 seconds so the gyro can initialize and determine center. If
the AXE CP V3 RTF is moved during this initialization, then
the gyro will not operate properly.
Always step 15 feet away from the AXE CP V3 RTF before
flipping any switches or operating the throttle. Do not hold
onto the model and run it up. Safety first.
RANGE CHECK
Ground check the operational range of your radio before the
first flight of the day. For safety reasons, unplug the main
motor so power cannot be applied to the main rotor blades.
With the transmitter antenna collapsed and the receiver and

8
transmitter on, you should be able to walk at least 50 feet
away from the model and still have control. Have an assistant
stand by your model and while you work the controls, tell you
what the servos are doing. If the controls do not respond
correctly, do not fly! Find and correct the problem first. Look
for loose servo connections or broken wires, corroded wires
on old servo connectors, poor solder joints in your battery
pack or a defective cell or a damaged receiver crystal from
a previous crash.
BALANCE THE MAIN BLADES
The AXE CP V3 RTF main rotor blades are already balanced
and ready to fly.
PREFLIGHT
IDENTIFY YOUR MODEL
No matter if you fly at an AMA sanctioned R/C club site or
if you fly somewhere on your own, you should always have
your name, address, telephone number and AMA number
on or inside your model. It is required at all AMA R/C club
flying sites and AMA sanctioned flying events. Fill out the
identification tag on the back cover and place it on or inside
your model.
AMA SAFETY CODE (EXCERPTS)
Read and abide by the following excerpts from the Academy
of Model Aeronautics Safety Code. For the complete Safety
Code refer to Model Aviation magazine, the AMA web site or
the Code that came with your AMA license.
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 aircraft 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 and deliberately fly my
models in a careless, reckless and/or dangerous manner.
5) I will not fly my model unless it is identified with my name
and address or AMA number, on or in the model. Note:
This does not apply to models while being flown indoors.
7) I will not operate models with pyrotechnics (any device
that explodes, burns, or propels a projectile of any kind).
RADIO CONTROL
1) I will have completed a successful radio equipment ground
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 the 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.
5) I will not knowingly operate my model within three
miles of any pre-existing flying site except in
accordance with the frequency sharing agreement
listed (in the complete AMA Safety Code).
9) Under no circumstances may a pilot or other person touch
a powered model in flight; nor should any part of the
model other than the landing gear, intentionally touch
the ground, except while landing.

9
CONTROLS
Always turn the transmitter on first and verify the idle up
switch is set to normal. With the AXE CP V3 sitting still, plug
the battery into the ESC. The AXE CP V3 will need to sit still
for 10 seconds so the gyro can initialize and can determine
center. If the AXE CP V3 is moved during this initialization,
then the gyro will not operate properly. Re-install the body
and your AXE CP V3 is ready for flying.
There is a safety built into the AXE CP V3 RTF that prevents
the motor from activating unless the collective stick has been
lowered to its lowest position. If the motor won’t run and turn
the main blades, please make sure the collective stick is all
the way down and leave it there for two seconds.
TRANSMITTER CONTROLS
All controls are described with the tail pointing directly toward
you.This is the best way to start out since it keeps the control
inputs oriented in the same direction. Once you become
comfortable you can work on side-in and nose-in hovering.
Trainer System:You can use acableto connect two transmitters
together and an instructor can take and give control back with
the release of a switch. Be careful not to hit this switch while in
flight as this would disable the transmitter output.
Idle Up Switch: Used for forward flight and aerobatics. This
switch raises the main rotor RPM and also changes the lowest
position on the throttle stick to around 40% throttle.This allows
the AXE CP V3 RTF to perform aerobatics and inverted flight.
This can be a dangerous switch since it raises the throttle. Be
extremely careful not to hit this switch accidentally or the
motor will instantly come on to at least 40% power.
Moving the cyclic stick right will cause the helicopter to tilt
right and start moving that direction.
Moving the cyclic stick left will cause the helicopter to tilt left
and start moving in that direction.
Moving the cyclic stick backwards (towards you) will cause the
helicopter to tilt backwards and start moving that direction.

10
Moving the cyclic stick forward (away from you) will cause
the helicopter to tilt forward and start moving that direction.
Moving the collective stick forward (away from you) will cause
the helicopter to climb higher.
Moving the collective stick backwards (towards you) will
cause the helicopter to descend.
Moving the tail rotor stick left will cause the helicopter nose
to move left (counterclockwise).
Moving the tail rotor stick right will cause the helicopter nose
to move right (clockwise).

11
TRACKING THE MAIN BLADES
At zero pitch, bring the main rotor up to speed and observe
whether the rotational planes of the blades are the same. If
they are not, adjust one of the linkages to bring the blades
into the same plane.
Apply the two different colored stripe decals to the tips of
your main rotor blades. These decals help identify which
blade is out of track.
The training gear is a big help to beginners. They soften not
so perfect landings and help to prevent the helicopter from
tipping over. Even if you have experience flying a helicopter,
please consider using the supplied training gear for the first
few flights.
FLYING
TAKEOFF
During your first flights it is important to have light winds and
a helper to keep an eye on things around you. Also, if you are
flying from grass, make sure it’s cut low as this will allow the
helicopter to slide around without catching. Also make sure
there are no obstacles in your flying area to distract you.
Slowly add power and observe the model. If you feel it needs
trimming, do so before lift off.You will find that model helicopters
never allow you to return the sticks to center. Simply hold
the sticks as needed to keep a steady hover. Please don’t
fight the trim too much as it is a normal thing to experience,
Winds have a large effect on model helicopters. Please wait
for calmer days and slowly work into windy days.
You will notice the cyclic controls lag slightly behind your
inputs. This is perfectly normal and something you become
accustomed to. It is normal to drift around some in a hover,
until you get used to flying the model. The cyclic controls
on the AXE CP V3 RTF are fairly sensitive so only small
movements are necessary.
HOVERING
Once the helicopter is in the air simply try to keep the
helicopter in one spot. This will take some practice and wind
has a big effect on the stability of the helicopter. Be patient
and slowly progress. Trying to rush the learning process can
be costly.
LANDING
Level the helicopter into a steady hover and slowly decrease
power until the helicopter settles onto the ground.
BASIC MANEUVERS
Once you are comfortable with hovering at different
orientations and landing, it’s time to move on to more
advanced maneuvers.
Slow Pirouettes: Add a small amount of tail rotor (left or
right) and try rotating the helicopter slightly sideways and
see if you can hold it there. If you become uncomfortable
bring the tail back towards you. Once you are comfortable,
try moving the helicopter to the side and turning back. Then
fly back to the other side in straight lines.
You can try rotating the helicopter around 360°, which is called
a pirouette. The helicopter can drift during this maneuver
so make certain you have plenty of room when you first
start practicing.
Nose-In Hovering: After pirouettes it’s time to move onto
nose-in hovering. The best bet is to wait for a calm day. Take
off and climb to 15 feet, practice half pirouettes from tail-in
to nose-in hovering, and try to lengthen the delay between

12
transitions. This will allow you to practice nose-in and still
give you a chance to get out of trouble. As you improve you’ll
remain nose-in for longer periods of time.
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
helicopter 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.
AEROBATICS
So you are getting comfortable in fast forward flight? Well,
now it’s time to slowly progress into aerobatics. Once you are
in forward flight start using the idle up switch which raises
the rotor RPM for aerobatics and allows the AXE CP V3 RTF
to fly inverted. Also, in wind it may be difficult to descend to
land without the idle up on.
Chandelles: Your first step is chandelles. Fly straight across
in front of you and pull up to a 45° angle. Now at the top, when
the helicopter slows down to a stop, apply left or right tail
rotor to bring the nose around 180° and continue back down
the 45° angle. As you progress with the maneuver you can
pull a greater angle than 45°, but 90° would be considered
a stall turn.
Loops: Once you become comfortable with the chandelles
and stall turns it’s time to move onto the loop. The key to the
loop is to enter with plenty of speed. Start pulling aft cyclic
to enter the loop and as the model transitions to inverted at
the top of the loop pull back on the throttle (towards negative
(–) collective) this will help maintain altitude. As the model
returns back to vertical add some positive (+) collective to
maintain the speed. One of the most common mistakes made
on loops is using too much negative (–) collective at the top.
Flips: Be certain to start with plenty of altitude. From an
upright hover slowly add in full forward cyclic and as the
model approaches vertical bring the collective stick back to
center. Now as the model continues to inverted you will need
to start adding in negative (–) collective (or pull the collective
stick back towards yourself). As the model transitions back to
vertical again bring the collective stick back to the middle and
start adding in positive (+) collective as the model returns back
to upright. It’s simply a matter of timing. The most important
thing is, do not throw the sticks around as this can cause the
head speed to drop and may cause the tail to drift.
Inverted Hovering: Keep in mind flying a helicopter inverted
is very difficult but can be learned. One of the main problems
is 3 out of 4 of the controls are reversed (forward/aft cyclic,
collective and tail rotor). You have to mentally reverse these
while flying. It will take some practice.
Take the loop you learned above and just hold the inverted
portion for short periods of time. As you become accustomed
to the reversed controls, you will extend the time inverted. It
is very difficult and will take some practice. Also, make sure
you have plenty of altitude for recovery if needed.
MAINTENANCE & REPAIRS
E-BOARD ADJUSTMENTS
Note: All of the e-board adjustments are pre-set and test
flown at the factory. If you replace the e-board with a new
one or need to re-adjust it for any reason, please follow the
guidelines below. Never turn these adjustments more than
180° and only use a plastic non-conductive screwdriver to
make the adjustment.
Tip: If you need to make adjustments consider using a
felt-tip marker and place a mark on the adjusters so you
can always return them back to the factory defaults.
Left/Right Bias: Is used to obtain a balanced feel between
left and right tail rotor inputs.The adjustment is very sensitive
so only make small changes. Turn clockwise to increase the
left tail rotor bias.
Gyro Gain: Turn clockwise to increase gain. Typically too
little gyro gain causes the tail to slowly move around and
drift. With the gyro gain too high, you will notice a very fast
oscillation in the tail known as “wag.” This adjustment is not
very critical so please don’t spend a lot of time trying to get
”the best” setting possible.
Tail RotorTrim: If the helicopter wants to drift one direction in
a stable hover then try using this adjustment. The adjustment
is very sensitive so only make small changes.Turn clockwise
to add right tail rotor trim.

13
SERVO SETUP
Note: The AXE CP V3 RTF is factory set-up and test flown
so there is no need to make these adjustments unless you
have damaged or changed a servo.
Servo arms are perfectly level when the throttle stick is all
the way down in normal mode (Idle Up Off). Helicopter left
side Servo A pushrod length should be 1.77" [45mm].
Servo arms are perfectly level when the throttle stick is all
the way down in normal mode (Idle Up OFF). Helicopter right
side Servo B pushrod length should be 1.26" [32mm] and
Servo C pushrod length should be 1.77" [45mm].
TAIL ROTOR REPLACEMENT
Use two small flat bladed screwdrivers to pry the old tail rotor
from the motor. Try to apply even pressure to both sides of
the tail rotor. When installing the new tail rotor please note
that the beveled portion of the hub goes in towards the motor.
Simply press the new propeller onto the tail motor.
SPINDLE REPLACEMENT
Before starting, make note of the 2mm nut used on the
bottom of each blade grip. When removing the blade bolt,
press upward on the nut to ensure it remains in the grip.
Remove the blade grip bolts using the 1.5mm hex wrench.
Then, remove the blades from the helicopter
Use a 1.5mm hex wrench to remove a spindle screw. Remove
the linkages from the blade grips. On the side where you
removed the spindle screw, carefully remove the blade grip

by pulling outward. Remove the dampening spacer. Pull on
the other blade grip and remove the spindle and blade grip.
If the O-rings come loose, simply press them back into the
head block.
New spindle installation. Apply threadlocking compound to
one of 2mm screws. Slide the 2mm washer onto the screw
and thread it into the new spindle. Slide one of the blade grips
onto the spindle followed by one of the dampening spacers.
Using a 1.5mm hex wrench, slide the blade grip and spindle
assembly through the head block. Make certain the O-rings
are properly seated and do not slide out the other side.
Place the other dampening spacer and blade grip onto the
spindle. Apply threadlocking compound to the remaining
2mm spindle screw. Slide a 2mm washer onto the screw
and install into the spindle. Using two 1.5mm hex wrenches
tighten the spindle bolts.
Snap the ball links onto the blade grips and re-install the
main blades.
MAIN SHAFT REMOVAL
Use a 1.5mm hex wrench to remove the head block retaining
bolt. Using a pair of ball link pliers remove the oval links from
the swashplate.While holding onto the main gear pull upward
on the main rotor head assembly. If the head is difficult to
remove simply try to rotate the main rotor head back and
forth while holding onto the main gear. Please note there is a
flat spot on the main shaft. You will not be able to rotate the
head more than a few degrees due to this.
Use pliers to grasp the 2mm nut on the main gear. Insert
a 1.5mm hex wrench into the main gear bolt and remove
the screw.
Insert a 1.5mm hex wrench into the main shaft collar set
screw and loosen. Insert another 1.5mm hex wrench into the
hole in the top of the main shaft. While holding onto the main
gear try pulling upwards on the main shaft. If you are having
difficulty removing the main shaft make certain you have
loosened the set screw on the main shaft collar. If necessary
try rotating the main shaft back and forth to help pull the shaft
loose from the lower gear. If you decide to remove the main
gear please note there is a small spacer located beneath it.

MAIN SHAFT INSTALLATION
Using the 1.5mm hex wrench and pliers to hold the nut, re-
install the lower main shaft bolt.
Insert a 1.5mm hex wrench into the main shaft collar set
screw. While pushing downward on the main shaft, pull
upward on the main shaft collar and tighten the set screw.
There should be no vertical movement in the main shaft
once you have completed this step.
Slide the main rotor head block back onto the main shaft.
Make certain the flat spot inside of the head block is aligned
with the flat spot on the main shaft. Use a 1.5mm hex wrench
to re-install the 2mm bolt head bolt.
OPTIONAL UPGRADE
This section is provided to help you install the optional
Futaba®GY240 AVCS heading hold gyro in the Heli-Max
AXE CP V3 RTF. This section may be omitted if you do
not intend to install this gyro.
Items Needed (must be purchased separately):
(1) Futaba GY240 AVCS Gyro (FUTM0809) OR (1) Heli-
Max HM4000 Heading Lock Gyro (HMXM1012)
(1) Great Planes®ElectriFly™C-12 Micro Brushed ESC
w/BEC (GPMM2015)
(1) W.S. Deans®Micro 2R Plug (WSDM3007)
(for C-12 ESC)
(2) Small Tie Wraps
Tools:
Solder and Soldering Iron
Wire Cutters
Installing a heading hold gyro into the Heli-Max AXE CP V3
RTF will make the model easier to fly.The gyro will now allow
you to focus your concentration on the other controls instead
of constantly flying the tail.
We highly recommend using the optional Great Planes
950mAh LiPo 11.1V 3s 15C battery (GPMP0401) for the
best overall performance.
INSTALLING THE GYRO
Use alcohol and a paper towel to remove any grease or mold
release agents on the gyro and helicopter frame. Apply the
double-sided foam mounting tape included with the gyro to
the bottom of the unit. Carefully align the gyro as shown in
the picture and mount the gyro onto the helicopter frame.

16
Solder a Micro Deans plug onto the motor wires of the C-
12 ESC as shown. The negative (–) motor lead (blue wire)
connects to the male pin on the connector. This will be
connected to the tail motor in a later step.
It will be necessary to solder the E-Board and C-12 ESC to
the battery connector as shown above. If you decide to use
the Great Planes 950mAh LiPo battery (GPMP0401), we
suggest installing a Deans Ultra Male Plug onto the ESC and
E-Board to match the connector on the battery pack. The
Deans Ultra Plug will better handle the increased current
draw of more aggressive flight as your skill level advances.
Using wire cutters, remove the Deans Micro connector from
both battery input leads on the E-Board and the C-12 ESC.
Remove 1/4" [6mm] of wire insulation from both the positive
(+) and negative (–) leads of the C-12 ESC and E-Board.
Compare the battery pack connector to the ESC connector
and verify the polarity is correct before soldering. Twist and
solder together the positive battery lead from the C-12 ESC
and the positive lead from the E-Board. Slide the supplied
heat-shrink tubing (included with the Deans Ultra Plug) over
the wires and solder them to the Deans connector. Repeat
for the negative lead. Slide the heat-shrink tubing up the wire
to the plug. Use heat to shrink the tubing.
Disconnect the tail motor plug as shown above and connect
the plug directly into the blue and white motor wires on the
C-12 ESC.

17
Since the E-Board provides power to the receiver and servos,
the BEC in the C-12 ESC must be disabled. Carefully lift up
the plastic tab on the C-12 ESC connector, remove the red
pin from the plug, and fold it back over the wire. Wrap a piece
of electrical tape or heat-shrink tubing around the connector
pin and wire. Plug the C-12 ESC into the GY240 gyro.
Remove the orange wire from the receiver and plug the
GY240 into the same position.Verify the black wire (–) on the
connector is towards the outside edge of the receiver. Now
plug the orange connector into the next available position on
the receiver (channel 5), and align it with the column of white
wires on the other connectors.
Use two tie straps to attach the gyro wires to the frame.Bundle
the wires and ESC together at the front of the helicopter.
On the gyro, set the “AVCS” switch to “ON” and set the “DIR”
switch to “REV”. Set the gain to 60% using the adjustment
dial on the gyro. If necessary, adjust the gain to match your
flying style or desired setup. The typical range of gain is 50%
to 75%.
Review your work and verify that none of the wires can
get caught in the main rotor gear or the swashplate. The
helicopter is now ready for the test flight.
FLIGHT INITIALIZATION
If this is your first time flying a heading hold gyro, be sure
to take your time and become accustomed to the new gyro
before jumping into your normal flying routine.
Turn on the transmitter, center the tail rotor trim tab, extend
the antenna, and verify the idle up switch is “OFF” (toward
the back of the transmitter). Connect the flight battery and
allow the gyro 10 seconds to initialize. The helicopter and tail
rotor stick must remain still during this process.
ARMING THE TAIL ESC
The tail motor ESC must be armed before each flight. The
best time to do this is after you place the helicopter on the
ground before taking off.
You will hear three beeps from the tail ESC once the gyro has
initiated. Carefully apply full right tail rotor and you will hear
4 beeps. Apply full left tail rotor and you will hear another set
of beeps. The tail ESC and motor are now armed and you
are ready to fly. If you need to pick up the helicopter, firmly
hold onto the main frame since the tail motor could operate
at any time. You can hold full left tail rotor on the transmitter
to prevent this from occurring.
FLYING
If the tail wants to drift slowly due to wind gusts, your gain
may be set too low. Increase the gain a small amount and
see if performance improves. If the tail has a tendency to
oscillate from left to right, your gain may be set too high.
Reduce the gain and see if performance improves.
GOOD LUCK AND GREAT FLYING!
