FD, what does PPMrecv stand for/mean in the CsvView Motor menu please?
Thats the answer I was looking for. Wasn't 100% certain of the reason for the max PWM and motor slow down causing the spin. And agreed on the app messages as well. BTW, did you look at the event log? Specifically the first line here. Landing? Just curious. The remainder is after the crash I believe.

I understand that, but there were 2 commands issued. Apparently only the second one worked. Point being is that the aircraft was already on the ground upside down when they were issued. Just looked odd....That's just referring to the RC command that stopped the motors.
That was after the spin began. You can stop beating the dead horse now. There is really no way to know for sure which is the actual cause. The effects are obvious.At 43.6sec the right back also started to get very erratic, presumably trying to compensate for the LF behaviour???
Ahh, thanks for that. I've always understood that ESC's operate utilising PWM (Pulse Width Modulation), when I was in electronics in the Navy they certainly did. not PPM which until now, as you realise, I'd not heard of!
Having now read about the two a bit more light has gleamed!

So with that gem of information and plotting the PPM signals to the motors, at the time of the in vitiation of the "falling" out of the sky at about 42secs, the front left pulses suddenly went to 100, maximin, and stayed there until ground contact. To me this would lean towards the ESC rather than the motor.

Your thoughts gentlemen, please correct me if my thinking is wrong..................
