Last week I broke two frame arms. Yesterday, I got a new frame, and put everything together again. The same motors, the same ESCs, the same flight controller, the same everything (except for the frame). This time I decided to rotate my flight controller 90 degrees, pointing right, for ease of access to the USB port. To compensate for this, I set the "Yaw adjustment" to 90. This seemed fine as I moved the quad around while looking at the instrumentation in the cleanflight gui. I also made sure to re-calibrate the accelerometer. Just in case something was different.
This morning I took it out to fly, and it was completely unflyabl. I would trye to take off but at about 40% throttle it started wobbling around like crazy. At 50% throttle, where all 4 points of the frame were off the ground, the wobbling got worse. Dropping the throttle made it flip over on its side. I lost 4 propellers before giving up. One time it shot right up into the sky while flipping only to fall down and break propellers.
I tried with pid controllers 1, 2, and 3 (MultiWii 2.2, Lux, and MultiWii 2.3). I tried in acro and in horizon mode. I tried setting the yaw adjustment to 270 (thinking maybe I got the orientation wrong). Nothing helped. It's the same wobbling. I also reset the pids to default. I have an increased yaw rate, which hasn't given me trouble in the past, but since I was only touching the throttle, I doubt that it has an effect. I also tried with different roll and pitch rates. The battery was fully charged, and the propellers were brand new. The motors are, as far as I can tell, connected to the right ports.
I also, technically, disabled current monitoring, but I highly doubt that has anything to do with it.
Nothing has helped, so now I need your help! What could the reason for this be? What am I doing wrong?
