I have noticed upon touchdown of the craft I hear to a greater or lesser degree a revving up of the
motors before idling down. I have gone to minimum throttle at 6" above ground and this still occurs.
I had a flipover recently due to this plus some light wind. I have been told to recalibrate the ESC
but I have heard this momentary rev up since then. Sometimes it is barely noticeable and some-
times it is very noticeable. Another problem I have had recently is for the craft to switch to the
LAND mode on its own. One time I noted the battery at 50% and another time at 30%. Since
then at normal, below 20%. Any comments along these lines would be greatly appreciated.
Thanks for reading and HAPPY FLYING.
