Also required is an appropriate battery charger for your
fl ight battery.
WARNING: To prevent the possibility of the main
rotors turning during set up, you must disconnect the
main drive motor from the ESC or remove the pinion
gear from the motor. Failure to do this may result
in injury to yourself or damage to the model and its
surroundings.

OPERATIONAL WARNINGS
CAUTION! A separate Battery Eliminator Circuit (BEC) must be used If you decide to change the stock servos (Futaba
S3114) to some other type of analog or digital servos. We highly recommend the Castle Creations CC BEC 10A Switching
Regulator (CSEM0005).
DANGER! Please allow a 10 minute cool down period after each fl ight for the Electronic Speed Control (ESC). Failure to do
so may cause loss of control due to the ESC overheating and shutting down.
DANGER! Please inspect the wooden main rotor blades before each fl ight for damage. If any damage is found or if the
blades have been crashed, please replace the blades before fl ying the model again.
CAUTION! If the rotor head speed ever drops suddenly in fl ight, please land the model immediately and remove the body.
Inspect the battery temperature and ensure that it has not exceeded 140°F. Also ensure that the ESC has not overheated.
The ESC does have a thermal protection built in that will reduce the power output to safe levels when the safe operating
temperatures have been exceeded. If this has occurred, please allow the model 10 minutes to cool down.
WARNING! The ESC does have a soft cut function that will reduce the power output to protect the fl ight battery. Toward the end
of a fl ight, if you notice a slight power reduction, land the model immediately and re-charge the battery. The fl ight time of the Axe
400 can be as long as 10 minutes, but this will vary depending on your fl ying style or how aggressively you fl y the model.
CAUTION! After a crash you must inspect all plastic and metal parts on the helicopter for damage before fl ying the model again.

*Leave the trim step set to 4 until the initial trim fl ight is completed. Then you can reduce the trim step to 1 for a fi ner

FINAL SET UP
Mount the receiver using double sided tape as shown below. Using a wire tie, bundle the wires and place them on top of the receiver.
This ensures that the wires cannot become entangled in the main rotor gear or the counter gear that drives the tail rotor.
Disconnect the main drive motor from the ESC. Turn your
transmitter on. Install a fl ight battery into the helicopter and
connect the battery to the ESC. Allow the gyro 5 seconds
to initialize.
Verify that you have disconnected the drive motor. Carefully
raise the throttle stick to the middle position. The servos,
blade grips and all the mixing levers should be perfectly
level. If necessary please make adjustments to the servo
arms, linkages or to the radio set up. Linkage lengths are
listed in the Heli-Max Axe 400 RTF manual.

PITCH RANGE
You may notice that the tail servo does not center when the
transmitter stick is returned to center. This is correct and how
a heading hold gyro operates. If the tail rotor servo always
returns to center, then you need to reverse the gyro gain
channel in the transmitter.
BEFORE FLYING THE MODEL
Once you have verifi ed the settings, please refer to the Axe 400
Ready To Fly manual for fi nal set up and fl ying instructions.
Thanks you for purchasing the Heli-Max Axe 400 Rx-R
and Happy Flying!

GYRO SET UP
With the transmitter on and the fl ight battery connected, pick
the helicopter up by the main rotor head and rotate the nose
to the left (counterclockwise). Verify that the pitch slider on
the tail rotor moves in toward the tail gear box, applying right
tail rotor as the correction.
