After Arming the board, when trying to take off, the vehicle flipped off instantly. Never it went to hovering mode. After giving 15 % throttle, quad flipped .
I have DYS 20Amp ESC, which when connected separately to DYS motor runs smoothly. I have performed Throttle Range Calibration, ESC is responding perfectly.
All ESC's were connected to Controller Board and gave perfect connection for Quad +
