I have a couple of Tarot T18’s with pixhawk2’s that have been flying Copter 3.5.2 for a while. I’d like to upgrade to Copter 3.6.0 to fix an altitude drift issue (this PR), however on initially flying it the vehicle seemed less stable than it did on Copter 3.5.2.
It wasn’t unstable to the point of crashing or anything, but the gimbal which had been able to stabilize the video when the vehicle had Copter 3.5.2 was not able to do so with Copter 3.6.0. I tried briefly to adjust the gains (decreased roll / pitch rates PI from .2 to .15 and increased the roll / pitch rate D from .01 to .015) but that appeared to make things slightly worse). I was limited on time and wasn’t able to try adjusting the gains in the other direction, but hopefully will this week when I go out and fly. Is there anything between the firmware versions that could cause this?
