Make sure that any mixing on AUX2 is
off before calibration.
Setup the throttle servo and linkage as close to
+/- 100% ATV as
possible.
Select the AUX2 channel to +100% and -100%
The system is now ready for
calibration. Calibration Procedure
The target rotor speed can be calculated using
the ATV
Calculator
Example 1): 2 speed setup:
Gear ratio = 9.3:1
ATV- = 39%, ATV+ = 72%
