5. Move both throttle stick and throttle trim on the transmitter to the "motor off" position.
Adjust the servo travel in that direction until the carburetor is closed. If the servo travel
must be greatly reduced in both directions, it is recommended that the linkage ball on the
servo arm is mounted further in so that the servo can be moved over a wider range. For
more information, refer to your helicopter's instruction manual.

With an electric model, the control range of throttle is crucial. Usually here the throttle
endpoints of the transmitter are fixed by an initial programming of the speed controller. But
some ESCs require adjusting the servo throw of the throttle channel in the transmitter, so that
the throttle range matches the specifications of the ESC. At Menu Point A you can verify this
setting. Carefully apply some throttle. The motor should start to turn immediately if you move
the stick just a little bit and full speed is reached when the stick reaches full throttle position.
If the motor turns much earlier at the maximum possible speed or only starts to turn at a very
high stick deflection decrease the travel of throttle channel in the transmitter or repeat the
programming of the ESC. The Spektrum AR7210BX RPM Governor can operate correctly, the
motor speed should increase as linearly as possible when the stick is moved and there should
be no range where the motor speed does not change.
WARNING: Electric motors rotate at high speeds. Always keep a safe distance
from rotating parts or personal injury may result.
Some motors may not be operated without load. In this case, only let the motor run for a
short time or let the motor stay attached to the main gear and only remove the main and
tail rotor blades.
When in doubt, skip the function test or throw adjust of the throttle stick.
