I recently upgraded to 3.1 on a trex 600 running digital servos and I am getting a random twitch. I thought at first it was the ppm encoder so I re-flashed it like I have done before on other APM flight controllers. After doing so I didn't see any changes and it seemed to twitch just randomly like before.
On another note I did see more twitching if I ran higher voltage to the servos.
Of course I haven't flow it in this configuration.
Has anyone seen this problem?
