Voxl2 Immediately loses RC
-
Hello, we are working with a Voxl2 board and 4-in-1 55amp Voxl FPV style ESC. we have been flying/building our aircraft with no issues binding and controlling with the Spektrum DSX transmitter. With our most recent build, when we arm the aircraft, it immediately goes into land flight mode as the RC loss failsafe gets triggered and the transmitter no longer communicates with the aircraft. Prior to arming we have full control, able to view our switch and throttle movements on the Radio page of QGC. After arming we have to do a full power cycle of the aircraft before our transmitter will be recognized via QGC and the aircraft again. The orange light on our rx stays on the entire time the transmitter is turned on, indicating that it maintains connection. We thought this might be a heat issue, but this happens from a cold start as well. our aircraft does contain active cooling and our IMU and CPU usually do not reach temps above 60C while on the bench.

We removed the RC and are able to fly with a wired gamepad.
Could the control loss be due to a voltage drop on the J19 12-PIN JST to the Rx? I will check later today.
