I'm trying to setup a T-Rex 550L with the Spirit Pro. When I get to the point in the setup to check stick inputs and corresponding swash movements, that's were I'm needing help.





In the Align manual I have followed the directions in in terms of servo to FC connections:

CH1 Servo -> CH1 on FBL
CH2 Servo -> CH2 on FBL
CH3 Servo -> CH3 on FBL

Here is what I get with stick movements. I'm in the US so Mode 2:

1. Left Stick UP -> Throttle and Pitch move to 98% and 100%
2. Right Stick Right -> Aileron moves to 100% (Servo 1 moves up, Servo 3 moves down, Servo 2 does not move)
3. Right Stick Up -> Elevator moves to 100% (All servos move down)

In the MZ-24 Pro radio I have selected swash type of 1Servo/Normal. SUMD is outputting on Channel 8 of the GR-24L RX.



I think the default channel mapping on radio is:

1. Throttle
2. Aileron
3. Elevator
4. Rudder
6. Collective pitch

Do I need to change the channel assignment on either the radio or Spirit?

Hello,

the problem is you have used Align manual for servo layout instead of the Spirit.

So CH1 servo from Align manual should be connected at the CH2 at the Spirit unit.
CH2 at the CH1 port.
CH3 at the CH3 port.

Hi @ZeXx86,

After swapping the connections per your instructions I'm getting proper movement.

Right stick pushed forward = swash tilts forward
Right stick pushed right = swash tilts right
Left stick pushed forward = swash moves up

Thank you for your help. Onto to the rest of the configuration.
