Hi CM and thanks for the reply.
Mine seems to happen in slow motion as it takes off, then stays there. I have had the bucking lots of times but as you say it settles down again... in my case to a 5 degree lean
The nice man at Aerox advised the sliding of the cage too, but it made no difference. Starts level, ends on the lean.
I did see your tied cable image earlier, but figured this wasn't the issue as they seem to be FPV cables rather than the Aerox cables. My lean happens whether I have my FPV cable plugged in or not. I don't know if it makes any difference, but when first levelling, the last bit (maybe 5 degrees) happens very slowly. It is now more evident as I have a Zenmuse on my other craft and it levels in a split second, almost magnetic speed. So I am just wondering if this slow levelling just doesn't get the chance when flying, although you would think by the time it lands on my bench it would have done it so probably best ignored!
Just going to attempt the sensor bit now. Presumably that is the small board sat on top?
Thanks again, will report back in a bit.
