Transmitter not moving controls

QGroundControl
1

Thanks in advance for patience, I’m relatively new in the technical depths here.

TL: Transmitter has no impact on function of flight control actuators or motors but they can be controlled via off-board with QGC.

System has PX4 6X(v2B), ELRS receiver, and Radiomaster Boxer transmitter.

  1. Transmitter is bound to rx via ELRS and appropriate CRSF settings in Parameters.

  2. (1) is verified, Transmitter stick and switch movements are shown in QGC on Radio tab and movements appear correct.

  3. Switch positions on transmitter yield the correct audio on PX4, ie. Armed, Modes, etc.

  4. Stick movement has no control over actuators or motors on the vehicle.

    I’m sure I’ve missed something here, but any pointers to resolve this and help move forward on configuring the drone?

So, did the RC calibration work in QGC? What PX4 version is this?

3

Yes, the calibration works in QGC just fine. Firmware is 1.14.3 via Holybro.

OK, issue resolved. There’s a COM_PREARM_MODE that can be set to AWAYS which allows RC control when disarmed.
