I decided to load up 3.5 rc2 onto my quadcopter. This quad flew pretty decent on 3.4 but I wanted to try the new autotune in 3.5 to see if it dialed things in a bit more. I tried to fly it to run an autotune last night but when I flipped the switch to start autotune, nothing seemed to happen. Since it was dark, I chose to wait until daylight to try it again. Today, I tried autotune again. At first it seemed as if nothing was happening. I turned it on and off several times trying to get some sort of action. After leaving it in autotune for a while, it did seem that it started to react. i thought it might have been a new intentional behavior. It quickly got very twitchy and then violently flipped itself upsidedown and propelled it into the ground. Not a fun moment. Still a complete novice in log analysis, so dont know what to look for. Can anyone tell me what may have caused this behavior, especially since 3.4 flights and autotune never yielded anything like this?
