"OK I figured it out really quickly. Its to do with mode switching. not sure why but for me i had something set to CH8 and i must have Ch8 set to mode switch in minim. So change that or your transmitter and you should be set.
hope this helps."

"I have this exact same issue. I had it working but then i changed some stuff around and now its broken.
For me, its works fine until i turn on my transmitter.Its hard to fly without a transmitter.
Did you every find a resolution?"
