I took the guts out of a old Iris+ and put most of the parts on a 470mm frame. I have a Q-Brain 4 in 1 25A ESC going to cheerwing 920KV motors. During standard calibration the motors twitch and one of the motors smoked a tiny bit. This is with a 5200MAH battery 11.1 3s from HK.(green) The unit claimed it was flashed with B-Heli and all I needed to do was standard calibration. Help would be great, thanks.
PS. Wired the Power module 1.1 to the Q-Brain to bring power to Pixhawk.
