The throttle connects to THRO channel (1)
The auxiliary connects to GEAR channel (5)
ATV setup [TRAVL]
Setup the throttle servo and linkage as close to +/- 100% ATV as possible.
Set the GEAR channel ATV 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 TRAVL v = 39%, TRAVL ^ = 72% GEAR Sw Posn Rotor RPM down (GEAR/INVERT) 1200 up 1500
Gear ratio = 9.3:1
TRAVL v = 39%, TRAVL ^ = 72%
GEAR Sw Posn Rotor RPM
down (GEAR/INVERT) 1200
up 1500
Example 2): 1 speed setup and disable:
Gear ratio = 9.3:1 TRAVL v = 0%, TRAVL ^ = 72% GEAR Sw Posn Rotor RPM down (GEAR/INVERT) Disabled up 1500
TRAVL v = 0%, TRAVL ^ = 72%
down (GEAR/INVERT) Disabled
Example 3): Flight Mode Mixing:
Set the throttle curves in Flight modes 1 and 2 above the throttle priority level.
Set the GEAR switch down to the (GEAR/INVERT) position Set the GEAR ATV [TRAVL v] to 0% Set the GEAR switch to the up position Set the GEAR ATV [TRVL ADJ] to +100% [MIX 3] - This mix disables the Governor in flight mode 'N' GEAR->GEAR Set the rate to -100% SW: ON [MIX 2] - This mix sets the target rpm to 1200rpm (39%) in flight mode '1' GEAR->GEAR Set the rate to +39% SW: F-S12 [MIX 1] - This mix sets the target rpm to 1500 (72% - 39% see note below) in flight mode '2' GEAR->GEAR Set the rate to 33 (see note below) SW: F-2
Set the GEAR switch down to the (GEAR/INVERT) position
Set the GEAR ATV [TRAVL v] to 0%
Set the GEAR switch to the up position
Set the GEAR ATV [TRVL ADJ] to +100%
[MIX 3] - This mix disables the Governor in flight mode 'N'
GEAR->GEAR Set the rate to -100% SW: ON
GEAR->GEAR
Set the rate to -100%
SW: ON
[MIX 2] - This mix sets the target rpm to 1200rpm (39%) in flight mode '1'
GEAR->GEAR Set the rate to +39% SW: F-S12
Set the rate to +39%
SW: F-S12
[MIX 1] - This mix sets the target rpm to 1500 (72% - 39% see note below) in flight mode '2'
GEAR->GEAR Set the rate to 33 (see note below) SW: F-2
Set the rate to 33 (see note below)
SW: F-2
Note: The MIX 1 rate is 72 (1500rpm) - 39 (1200rpm) = 33%
Hint: You can observe the auxiliary setting by using a spare servo.
