I found this topic in "troubleshooting", but the suggestions didn't help.
The plane has been working fine in FBWA, auto, etc., but would only operate in manual mode today. I don't see any errors in HUD or from telemetry logs.
I DID make a change today -- I replaced 3dr radios with RFD900s. Everything telemetry-related seems fine though -- HUD info is all correct (flying in manual). I can read/write waypoints, and at least on the ground, the HUD correctly displays as I switch modes between stabilize/manual/fbwa. There's just no activity to the control surfaces, or throttle, except in manual mode. Pixhawk main LED is solid green. No errors in HUD, nor helpful messages in telemetry logs that I can find.
Should I switch back to 3dr radios? Anyone else had problem with RFD900s & pixhawk? This doesn't seem related to radios, but it's all I'm aware I've changed...
I'm flying Skywalker 2014/Pixhawk w/ 3dr gps/compass, spektrum satellite receiver, 2.78b firmware.
