ELECTRIC MOTOR WARNING

Electric-powered models are very dangerous due to the

high power they are capable of generating instantly. Please

remove the pinion gear or unplug two of the motor wires

while working on the model.

TRANSMITTER FUNCTION SWITCHES

The Dual Rate Switch changes the control rate of the

helicopter. The High Rate provides the maximum control

which is necessary for 3D ﬂ ight and aerobatics. The low rate

reduces control throw which makes the model easier to ﬂ y.

The low rate is recommended for your ﬁ rst ﬂ ight. Once you

have become accustomed to the AXE 400 3D RTF please

feel free to use high rate if you prefer.

The Throttle Hold Switch is used to disable the power output

of the motor but has no effect on the other controls. The

Throttle Hold Function was originally intended for autorotation

landings (off power descent to landing; this maneuver is

extremely difﬁ cult and it is recommended that you do not

attempt it unless you have no other choice).

In addition to autorotation the throttle hold function can be

used as a safety switch while handling the model since it

disables the motor. Turn the transmitter on and set the Throttle

Hold Switch to the on position. Now you can safely connect

the ﬂ ight 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 ﬂ y.

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). Disabling

the motor before a crash will prevent a lot of damage.
