Binding to Genius CP very slowly

Hello at all
first: I´m german and my english will not be the best.
second: binding my Devo 10 (latest nightly) to Genius CP (devo) causes problems. After binding (led on) channel 6 (pitch) works fine, but elevator, throttle etc will not work and led on Genius CP starts blinking. Sometimes suddenly all funktions are working..

Has somebody the same probs?

I would say first thing to check is if your antenna still well soldered to your board.

Had almost same behavior with old walkera models and it was antenna or crystal pins on the rx broken
