Hi I am new to Quadcopter. Recently, I built a F450 frame quadcopter with APM 2.8 and I use Mission Planner 1.3.45 with ArduCopter firmware V3.2.1. I do a motor test, all works for me except test all in sequence. When i test all in sequence only the first motor (top right) spins, then nothing happens after the first motor stops.

The transmitter is not showing any PPM readings, just some random noise observed occasionally, it is not bringing me anywhere. Can I know... Read more ..read more
