"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."
