OPERATIONAL WARNINGS
OPERATIONAL WARNINGS
●Please allow a 10 minute cool down period after each flight so the
motor controller and motor can cool down. Failure to do so may cause
loss of control due to the controller overheating and shutting down.
●Inspect the main rotor blades and blade screws before each flight for nicks
or loose components. If any damage is found or if the blades have been
damaged, replace the blades before flying the model again.
●The motor controller has a soft cut function that will reduce the power output
to protect the flight battery. Toward the end of a flight you will notice a slight
power reduction. Land the model immediately. The flight time of the AXE100
SS/SSL can be as long as 6 minutes (Standard Hover) but this will vary
depending on your flying style.
●After a crash you must inspect all plastic parts on the helicopter for damage
before attempting to fly the model again.
●Always unplug your battery from the helicopter after use.

TRANSMITTER (RTF Model)
TRANSMITTER (RTF Model)
Please fully read the transmitter manual included with
your helicopter to learn more about how to use and
adjust your TX610.
IMPORTANT TRANSMITTER FUNCTIONS
The Throttle Hold Switch (HOLD/
FLAP) is used to disable the power
output of the motor but has no
effect on the other controls. The
throttle hold function is intended
for autorotation landings off power
descent to landing; this maneuver
is really not realistic with a motor
driven tail. In addition to
autorotation the throttle hold
function can be used as a safety
switch while handling the model
since it disables power to the motor. Turn the transmitter on and set the throttle
hold switch to the on position. Now you can safely connect the flight battery
without having to worry about inadvertently moving the throttle stick once you
place the model on the ground. Verify that the idle up switch is off and the throttle
stick has been moved to its lowest position. Then, simply turn the throttle hold
off. The model is now ready to fly. Another use for the throttle hold function is
to disable the motor before a crash without having to drop the collective stick,
possibly forcing the model into the ground.
The UP-1 function is enabled and
ready to use. The UP-1 switch
(UP-1/GEAR) function is used for
aerobatics and 3D flight. If you are
a beginner to aerobatics,
remember this switch sets the
motor speed (see your TX610
manual for details) while still
allowing positive and negative
pitch control. This means if you
get confused flying, pulling the
throttle stick back WILL NOT decrease the power to the motor but rather add
power. Hence it’s a good idea to learn to use the Throttle Hold Switch when you
feel a crash is imminent!

7
It’s also important to know that your TX610 transmitter is capable of a system
reset. (See how this is done in the TX610 Manual.) If you decide to do a system
reset, the factory setup numbers to the Heli-Max AXE100 SS/SSL are listed here.
Below are the factory default parameters (Model Memory 8) for your AXE100

GETTING THE MODEL READY TO FLY
GETTING THE MODEL READY TO FLY
INSTALL BATTERIES IN THE TRANSMITTER
Remove the battery cover from the
back of the transmitter and install
eight “AA” batteries into the
transmitter. Double-check the
polarity of each battery before
replacing the battery cover.
CHARGE THE FLIGHT BATTERY
Plug the wall power supply into any
110V standard outlet. Plug the
remaining 4mm plug into the side of
the charger box.
The center front panel LED will light
letting you know the charger has power.
Plug the helicopter’s power battery into
the open connector of the charger. The
charger will beep twice letting you know
the battery is connected.

9
At this point you can select a slower or
faster charge rate by pressing the - or
+ buttons located on the face of the
charger. While the LED is illuminated
you will need to press the charge button.
You will hear 3 beeps and the charge
cycle will begin.
When charging is complete, all the LEDs
will flash and you will hear a steady set
of beeps coming from the unit. Unplug
the flight battery. It is now ready to use.
NOTE: Your battery charger ranges from .3AMPS to .7AMPS in .1 amp increments.
The higher this value, the faster the battery will charge. We recommend charging
on the .5AMP setting (Default).
TURN THE TRANSMITTER ON
Verify that the HOLD/FLAP and UP-1/GEAR functions are off and slide the
power switch up to turn the transmitter on. If the transmitter is turned on with
the HOLD/FLAP, UP-1/GEAR or throttle stick forward, the screen will show “3D”
or “T-H” and a warning will sound. Turn the HOLD/FLAP and UP-1/GEAR
functions off and move the throttle stick to the low position to continue. Now is
a good time to make sure the electronic trim buttons on the transmitter are
centered. We do not need to use them as the Incredible Heli-Max TAGS™ system
controls all flight center trims.
INSTALL THE FLIGHT BATTERY
Slide the battery into the helicopter.
Make sure the battery is slid all the way
to the front of the battery tray.
Make sure the battery wires don’t come
in contact with any of the rotating parts.

10
Once the flight battery has been connected, always handle the
helicopter as if it has full power available. The helicopter must remain
still for the gyro to initialize properly. This process is instantaneous
after the helicopter is held still. Turning off the HOLD/FLAP switch
the helicopter is ready to go. Now is a good time to turn on the HOLD/FLAP
switch until you are ready to start flying.
Your AXE100 SS/SSL uses the Tactic SLT™
protocol. This means, with the simple addition of
the Tactic Anylink
™
to your favorite transmitter,
you can enjoy your Heli-Max AXE100 SS/SSL
with a familiar transmitter, “YOURS”. After the purchase of your Anylink, make
sure to fully read the instructions so you understand how to properly and safely
use the Anylink system.
When using the Anylink you must make sure to follow the proper
mapping procedure for your radio system. Failing to do so could
cause an unsafe condition. How to map your transmitter, as well as
a list of compatible transmitters, is included with your Anylink. You
can find this and more information on the Tactic website, www.tacticrc.com
®
LINKING
LINKING
Your AXE100 SS/SSL RTF comes with the transmitter pre-linked to the helicopter.
The Tx-R version requires you to complete this using your transmitter and an
Anylink. Also, if you need to link or re-link for any reason, here is the proper
procedure to do so.
To identify if your transmitter is linked to the helicopter, first turn your transmitter
on, remove the canopy (see removing the canopy in the maintenance section
of this manual), and view the LED closest to the link button. It should remain
steady on. If it does not and is flashing your transmitter is not linked to the
helicopter. To link the transmitter to the helicopter follow the below procedure.
1. Turn on the transmitter, making sure all the switches are in the back position
and the throttle is down.
2. Remove the canopy from the helicopter and locate the small black
button near the front of the PC board. Next to it will be an LED (flashing
if not linked).
3. Place the transmitter in close proximity to the helicopter (1 to 2 feet away).
4. Press and hold the push button for 3 seconds or until the LED remains on.
™

11
5. Monitor the flashing LED. When it
stays on without flashing, your
transmitter is now linked to the
helicopter. Note: there is a second
LED in the center of the PCB. When
your transmitter is linked and the
helicopter held still this LED will
flicker, letting you know your
TAGS™ stabilization system is
working and ready.
TRANSMITTER SETUP GUIDELINES TO HELP YOU GET STARTED
FUTABA: You will find that regardless of the Futaba system you choose, the
basic setup is the same. This includes the Futaba 6EX, 7C, T6J, TJ8 as well as
others. We have listed the setup of a Futaba T6J transmitter. It’s also worth
noting that even though the AXE100 SS/SSL uses 120 degree CCPM (Cyclic-
collective-pitch-mixing), with the Heli-Max TAGS system you must select the
90 degree swash arrangement. In a Futaba system this is called H-1 or 1-S
under swash type.
The setups listed are will get you going and might suit your flying style. If not
please feel free to make adjustments to suite your flying style.

FLYING YOUR AXE100 SS/SSLFLYING YOUR AXE100 SS/SSL
Takeoff: During your first flights it is important to have light winds. Also, if you
are flying from grass, place a rubber mat or pad down on the grass so the small
rotating parts don’t get hung up.
Turn off the hold switch and very slowly add power and observe the model.
During “spool up” It is important to note that the torque of the main blades can
cause the helicopter to rotate slightly clockwise. This is normal.
Your AXE 100 SS/SSL has the incredible Heli-Max TAGS system. The TAGS
system takes care of all center trim function the transmitter. Having said this
you do not need, or want, to move or adjust the trim buttons during flight. If you
notice any slight flight drifting give it some time. After the helicopter’s swash
and servo links “break-in” the drift will diminish.
Hovering: Once the helicopter is in the air simply try to keep the helicopter in
one spot. This will take some practice. Remember that even a light breeze will
have an effect on the stability of the helicopter, so please take your time. Be
patient and wait for a calm day.
Landing: Level the helicopter into a steady hover and slowly decrease power
until the helicopter settles onto the ground. You might notice as the helicopter
is ready to touch down it moves around a little. This is normal as the helicopter
enters ground effect. Remember to unplug the battery from the helicopter after
your flight is complete.
BASIC MANEUVERS
Once you are comfortable with hovering in one place start working on orientations.
By this we mean to say, hover the helicopter 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: 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 you will want to 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.
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.

14
AEROBATICS
So you are getting comfortable in fast forward flight? Well, now it’s time to slowly
progress into aerobatics. Your AXE100 SS/SSL is more than capable of full
aerobatic performance. Once you are in forward flight start using the idle up
switch. This switch raises the rotor RPM and allows the blades to progress into
negative pitch for aerobatics and inverted flight.
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. 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. 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 difficult but
with practice it 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. Also, make sure you have plenty of altitude for recovery if needed.

MAINTENANCE
MAINTENANCE
TOOLS NEEDED
●Small screwdriver (provided)
●Soldering iron
We will describe a few simple repairs
that you can do to your helicopter. We
will list them as “removing” with the
understanding that to reassemble one
just follows each step again from the
bottom up. NOTE: It’s a good idea to
keep a magnet handy to help secure
the small screws. You can also use this
magnet to “magnetize” your screwdriver; just rub the end of the screwdriver on
the magnet for a few seconds. This works nicely to keep the screws in place on
the tip of the screwdriver. TIP: we use a small piece of white paper over the
magnet to help see the screws.
REMOVING THE CANOPY
Carefully pull the back edges of the canopy outward, sliding the rubber grommets
off the pegs. Then side the canopy forward.

16
REMOVING THE MAIN BLADES AXE SS
Using the provided screwdriver remove the main blade screw from the blade
grip. Side the blade out of the grip.
REMOVING THE MAIN BLADES AXE SSL
Using the supplied screwdriver remove
the main blade screw from the blade
grip. Carefully side the blade from the
grip and unplug the LED power wire.

17
REMOVING THE TAIL BLADE
Hold the motor firmly and pry the tail blade off using your fingernail or small, flat
blade screwdriver. Use your finger to press the new blade in place. NOTE:
When reinstalling, do not force the blade tight against the motor.
REMOVING THE LANDING GEAR
A total of 6 screws hold the battery tray/
landing gear in place. Using the supplied
screwdriver remove the 6 screws.
REMOVING THE MAIN GEAR AXE SS
After removing the landing gear, use the supplied screwdriver to remove the
screw that holds the main gear in place. Slide the main gear away.

18
REMOVING THE MAIN GEAR AXE SSL
After removing the landing gear, scrape
away any adhesive holding the wires to
the solder lugs. Unsolder the two wires
from the gear contact posts. Using the
supplied screwdriver, remove the screw
that holds the main gear in place. Slide
the main gear away, carefully snaking
the two wires though the center hole.
REMOVING THE MAIN SHAFT
Remove the landing gear, and remove the main gear. Using the supplied
screwdriver loosen the two screws on the lock collar. Remove the ball links that
attach the servo pushrods to the swashplate. Remove the links from the blade
grips. Slide the main shaft and head from the helicopter and remove the screw
from the head block. Slide the main shaft away. NOTE: When reassembling,
it’s important to set the shaft lash using the lock collar so as not to be too loose
or too tight.

19
REMOVING THE FEATHERING SHAFT
NOTE: You will have to provide a second small phillips screwdriver for this step.
Remove the blades from the blade grips as described above. Place a screw
driver in the end of each blade grip and engage the screws. Unscrew the screws
and one of the two will remove. Slide the blade grips off, being very careful to
not lose any parts. Note the direction of the silver spacer washers.
REPLACING AN AFT SERVO
Remove the canopy. Remove the link from the swashplate. Unscrew the screw
from the attachment bar. Carefully place pressure on the bar back, and then
slide off the servo tabs.
Snake the wire out of the loom and then unplug the servo.

20
REPLACING THE FORWARD SERVO
Remove the canopy. Remove the link from the swashplate. Unscrew the two
screws from each side of the servo mount. Snake the wire out of the loom and
then unplug the servo.
REMOVING THE TAIL BOOM
Remove the canopy. Unplug the connector leading to the tail motor. Snake the
wires away from the bundle. Grasp the tail boom and pull it away from the main
frame. If you find the boom hard to remove, use a drop of CA debonder on the
parts and allow that to work into the joint before you try to remove it again.
