Hi,
after a not so positive experience with my first outdoors flying test yesterday, I have a few questions and a maybe a suggestion.
It would be great for us newbies if a couple of experienced AC pilots got together and wrote up a list of dos and especially DO NOT DOs when learning to flight testing and learning to fly ACs.
How I have come to this suggestion should be clear from my following questions.
Now for the question part:
a) how much instability would you expect when descending straight down through your own propwash?
I found that the level of instability was probably approaching the limits of what the stabilisation code can deal with.
b) I had a crash yesterday which happened when the copter was moving forward at cca. 4m/s in a gentle (cca. 1 in 10) descent. At an altitude of about 1m I applied about 80% throttle and a bit of back stick to stop the copter for a low hover. The copter again seemed to enter its own propwash and instantly flipped on its back (left to right) and crashed quite violently.
Does this sound like pilot error (ie. perform this maneuver at a higher altitude without the possibility of ground effect) or a tuning/code error? I have checked all motor connections and battery state after the crash and all was in order at the time of the crash.
Thanks,
Hans
