JR 9X Setup

The throttle connects to THRO channel (1)

The auxiliary connects to AUX2 channel (7)

Make sure that any mixing on AUX2 is off.

ATV setup [TRVL ADJ.]

Setup the throttle servo and linkage as close to +/- 100% ATV as possible.

Set the AUX2 channel ATV to +100% and -100%

Hint: You can observe the AUX2 range on the [MONITOR] screen

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

(MIDDLE)                       Disabled

(UP)                                1500

Example 2): AUX3 channel sets RPM

The throttle connects to THRO channel (1)

The auxiliary connects to AUX2 channel (7)

ATV setup [TRVL ADJ.]

Setup the throttle servo and linkage as close to +/- 100% ATV as possible.

AUX3 is already mixed to the flight mode switch. The ATV in normal flight mode is +100, in flight mode1 the ATV is 0 and in flight mode 2 the ATV is -100.

Set the AUX3 ATV [TRVL ADJ] to 100% in N and Flight S1 and S2 switch positions.

Remove any V curves or idle up curves (they can be restored after calibration) on the throttle in S1 and S2 flight modes.

Inhibit any mixing on AUX3. Toggle the flight mode switch to enter and leave calibration

Two mixes are used to add offsets to AUX3 in each flight mode so that, in this example, Normal mode disables the Governor, flight mode1 sets 1200 rpm and flight mode2 sets 1500 rpm.

Hint: You can observe the AUX3 range on the [MONITOR] screen

[PROG.Mix1] - This mix flattens the AUX3 channel to disable the TJ in each flight mode switch position.
