I am on my way to build my first ever quad copter. I am using Pixhawk4 flight controller. After arming my quad copter for the first time, the Motor 2 emitted smoke. I replaced the motor. After that same thing happened this morning with Motor no. 4, smoke coming out.
I checked thoroughly for any long screw issue which may touch the coils but nothing found. No screw is touching the coil.
A few minutes back I made a video and put at that to youtube showing that I can Arm and Disarm from Mission Planner software. But as soon as I am putting my battery and try to arm in real time, the motor burns. Not sure, what to do. Please advise.

Looking for your kind help.
