I've been using a 3DR RTF Y6b with Pixhawk since early summer with no problems. I never play with parameters. I normally would fly with the tarot gimbal and GoPro camera, but I wanted a better camera option for my purposes so I have a stable mount with a Canon Powershot attached. I've been swapping out back and forth the tarot gimbal with GoPro camera and my DIY mount with no problem most of the summer. Just recently, when I was flying with the Canon camera, my Y6 started twitching and bouncing around erratically in loiter mode. When I switched it to auto it would perform a mission just fine.
A couple flights after this began, it's now been displaying that same jumping and twitching behavior in stabilize, loiter, and auto. It is jumpy enough in auto where my photos actually turn out blurry because of the sudden movements.
My question is does anyone know if this is a tuning issue that I would just have to change parameters when I swap camera mounts? If so can someone suggest which parameters? I am a beginner and I have list of changeable parameters but I have no idea where to begin. I've sent the log files in to 3DR Support, and they've checked everything and can't see anything unusual. Also, i'm not sure if this would solve the issue anyway, since its been working just fine most of the summer and I feel that the weight is pretty balanced with my DIY mount.
The only other thing I considered is the temperature drop this month. Does anyone have any experience on how cold of temperatures these things can fly in?
I appreciate any help, Thanks!
