Spektrum SPMAR7200BX - Manual (Page 23)

To find the optimal gain:
1. Start with a low gain value where the tail will feel very weak.
2. Increase the gain step by step until the tail feels more precise and holds better
on sudden pitch inputs.
3. If the gain is too high, “wagging” will appear in fast forward or backward
flight.

A. Swashplate Cyclic Center Adjustment
NoTICE: NEVER USE TRANSMITTER TRIMS WITH THE AR7200BX!
The AR7200BX will interpret the trim as a control command, NOT as servo trim.
Menu point A allows you to easily adjust your servo centers at the flying field if
the helicopter is wobbling during pirouettes or not climbing out straight on quick
pitch inputs.
Parameter menu point (A) adjusts both the aileron and elevator servo centers
without regard to the individual servos.
To adjust the aileron and elevator servo centers:
1. Move the aileron or elevator stick in the desired direction.
2. Repeatedly move the stick or hold the stick to move several trim steps at once.
3. To delete the trimming, move the tail stick in any direction.
