Hi all, I seem to be having some issued in auto mode. I'm running 2.8.1 on the board, and mission planner 1.2.18.
Basically, the quad hits the first waypoint and heads for 2, then will turn back to 1, hit it then head for 2 again. 95% of the time this happens between the first 2 waypoints. On my last test flight I gave it 3 waypoints, almost in line with one another, and instructed it to loiter unlim at wp3. I decided to just put it into auto and let it do its thing until I ran out of juice. After watching it take a few runs at it, mostly unsuccessfully, it did manage to get through all three wp's and loitered for about 5-10 secs, then went back to wp 1 and started from the beginning again.
After closely watching the log file in mission planner it seems to jump from auto to stabilize for just an instant, then back to auto, which perfectly explains why it keeps returning to wp 1. I just can't figure out what's causing it to jump out of auto. There really doesn't seem to be any sort of pattern or regularity to when it does it either.
I've attached the .tlog from the latest flight, skip ahead to about 13-14%, that's when I put it into auto mode initially.
I would really appreciate some help with this one.

Well I seem to have isolated the problem to a slight fluctuation in the pwm signal out of my tx. I'm using a spektrum dx8 and have two 3-position switches to choose from. I am able to adjust the two end points pwm output, but not the center position. The fluctuation is pretty small, but because the output in center position is ~1504 and the cutoff for the next mode is 1490 it is just a little too close for it to stay in the mode that I've selected.
Does anyone know if it's possible to tune my dx8 so that it would sit around 1530 or 1540 in that switch position? Or at least stop it from fluctuating? Alternatively if it were possible to adjust the pwm ranges within mission planner so I could potentially bump that 1490 cutoff down a bit.
