I've just completed a new quad build, but on takeoff it will constantly yaw anticlockwise, and no amount of right yaw stick will stop it.
I've checked that all motors are aligned, going the correct direction, and the correct props are attached. It responds correctly to all inputs during a hand test, even yaw, but the yaw response feels weak. Also double checked the RC channels and adjusted subtrim so they're all reading 0 with sticks centred.
Looking at the log, mot_yaw jumps to 1000 upon takeoff. I haven't seen this before, and I can't seem to track down the cause of it for now. Help would be appreciated if anyone's got any ideas!
I'm Running r396 w/DIMU.
Motors:
A = 5
B = 11
C = 12
D = 6
