I've built a quadcopter using the Dji Wookong-M. As of a couple of weeks ago I have been able to get everything to work except for one small thing. When I throttle up the Drone tends to flip to the side. I have tested all the motors over and over again and I know that they are spinning the right direction and that I have the right props on the right motors. I tested on both grass and concrete but both times it flipped. It starts to flip once the throttle is past 50%. I don't know if it is catching or if something is off balance although I don't think this is the problem since the quadcopter tips different directions almost every time. If any one could tell me what is wrong I would appreciate it a lot since my project is due in 2 1/2 weeks.
Thanks in Advance
