rolandash Hi, finally I save my parameters into my pc drive. However, today, it reset again after a failsafe initiation. It fell from about 2m high on carpet. I think the falling, the impact was not that bad. But it reset again. The worse thing is that after I load the parameters from the drive. I cannot arm the drone anymore. At first I thought it damaged the 4 in 1 ESC. So changed a new ESC. But it still behaved the same. It behaves like: if it is the first arm from remote controller, the motors will rotate 0.5s I think, and stop. If I tilt the drone forward, only 2 forward motors can rotate at a very low speed. If titled backward, the back 2 motors will rotate. After the mindracer signal LED blinks white, which means disarm after arm if no extra signal received, there will no signal anymore.
I recalibrate the radio, it still behaves the same. So I think the radio, controller, and ESC should be good. Do you know what is the possible reason? Is it the power distribution board or the mindracer (the mindracer LED behaves normal I believe). I also ordered both pdb and mindracer. Hope they can arrive soon.
