"Hmmm, i was thinking of tapping in to the gimbal power using a y shaped JST harness. I know the voltage to the gimbal is protected by a regulator but not sure if it's low enough for the LEDs (4v-12v). Maybe I could fi the switch in this arrangement…"

"But where did you take your power for the LEDS from?"

"Anyone else having this problem?"

"Thanks.  May go down the storm route myself. Although if I'm not getting a signal out of pixhawk there may be not much point. Just to confirm.
RC9_Function set to 1 (for pass through) I think mines currently set to 7 for mount_tilt."

"Any news on this? Having a hell of a time just trying to control pitch with my receiver.  I had it working on previous versions of Arducopter. Now running 3.3. I guess I'll have to go back to 3.2 and see if it makes any difference.  So frustrating."

"OK thanks.  My problems seem to stem from not having a fully charged battery on the copter.  The Battery had enough volts left to power flight but not initialise the video link.  Seems strange."

"I wondered if you made any progress with this? I'm having the same problem. Very frustrating."
