OK after analysing my txt and dat files the cause of a 'medium' crash was due to the right stick getting stuck in a 43% (0.28 in data) move right position while coming into land.

All the data shows that it stuck precisely on 43% for 3 seconds, then after another touch of the stick it returns to 43% for another 2 seconds.

Given this was a week old P4P this was not in my opinion user error when the primary control of the craft is from the RC unit.

As the data shows it in a stuck position, ie: no wavering at all from 43% (0.28) and it returns to it after adjustment - what do you think?
Note: the -0.64 down throttle is the same as 100%, so full down hence the consistent number...

For anyone interested

I think this spreadsheet shows the RC stuck extracted from the txt file...
So from time of 122.9s to 125.5s it sticks on 0.28 aileron. Now you could say this was just a very steady finger on the stick, but a human could not produce a rock solid position like that especially during a landing procedure. Even if they could, the most significant is that after some adjustment between 125.6s and 126.2s the stick returns to precisely 0.28 from 126.3s to 127.8s ... The pilot here was completely unaware that the stick had 'not' returned to the central zero position in the 3-4 seconds where the p4p just appeared to be drifting of it's own accord. A faulty new RC unit.
