RV6a. Sv 32 roll servo. D100 AP 74 and hs34. I have the sensitivity set all the way down to 1. The stick still has ? twitching ? , stick jumping back and forth. Does not twitch all the time but probably every 10 to 15 seconds for probably 4 or 5 bumps. If I set sensitivity higher say at the factory 10 it gets more pronounced. Higher setting and almost out of control. Any suggestions?
