Hold scroll and channel, and then turn on radio.
Set AUX to 2P and GBC to 2P.
Turn off radio and turn back on.
Go into your settings like normal, get to mix, set everything at 0 (that was my problem)
Then just set your epa's and everything on the third channel according to how far you want your servo to go etc. My epa's on my dig are set at 100 both ways.

Got any q's ask.
