Why is my quadcopter toppling when i try to fly it? Answered
I built a quad copter. I have done all the calibrations correctly (accel, compass, rc, esc). When I arm the drone, motors and propellers are spinning. But when i give more throttle to try to hover it, it doesnt fly upward steadily. Instead it lifts backwards and falls. Why is this happening? Should I change some PID setting?
