Doing Esc calibration (transmitter on, throttle up, plug in battery, listen for beeps, unplug battery, plug back in, listen for more beeps, throttle down) motors spin, throttle works fine. When I get out of calibration mode (unplug battery, plug back in), I can't get the motors to run. Is there something I'm missing? I don't know what to "blame", the Arducopter or the ESC (4-1 Qbrain).Thanks.

That's the problem. It won't arm in flight mode. The red light blinks fast and the motors twitch. I can arm and disarm while in calibration mode, but not in normal mode.

Are you sure you've armed the copter?
