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%

 

AUX2 Sw Posn     Rotor RPM

(DOWN)                 1200

(UP)                        1500

 

Example 2): 1 speed setup and disable:

Gear ratio = 9.3:1

ATV- = 0%, ATV+ = 72%

 

GEAR Sw Posn     Rotor RPM

(DOWN)                 Disabled

(UP)                         1500

 

Example 3): Flight Mode Mixing:

        Set the throttle curves in Flight modes 1 and 2 above the throttle priority level.

Set the AUX2 switch to the down position

Set the AUX2 ATV [TRVL ADJ] to -0%

Set the AUX2 switch to the up position

Set the AUX2 ATV [TRVL ADJ] to +100%

Perform the following mix setups with the AUX2 switch in the UP position.
