I always arm the ship in stabilize mode, and I will give more throttle next time.
Also, I notice in the "Test Motor Ballance" line of that log analysis there are 6 values given. I only have 4 motors. Could that be part of the problem? I am quite sure I had quadcopter set as the frame type when I started calibrating it in Mission Planner.
Motor 4 seems to be slow to start spinning when I arm the quad. But I also notice that the last 2 times I did a motor calibration, none of the motors started spinning at the end. I had to give them a little throttle in order to get them to start up.
