So I had a crash a while back and ever since, my ship has been intermittently bouncing around in the air and feeling very unstable. (I don't know if this particular problem is related to the crash, but I thought I'd mention it.)
So I ended up replacing literally every single part in the powertrain, and I have been testing it without my FPV system attached. (all my FPV components are attached to the top plate of the QAV250 and disconnect with one cable to the PDB.)
I replaced my Kiss ESC's with DYS SN20 and flashed them to BLheli 13.2. When that didn't fix the bouncing, I replaced the naze32 board, the QAV250 PDB, my 5V BEC, and eventually all 4 motors (Cobra 2208 2000Kv) when nothing fixed the problem.
After all that, I found that the bouncing and erratic power cutouts are decreased somewhat when I swap on some 5x4.5 props rather than my 6x4.5....
I can't imagine how this problem showed up after a crash, but I think it may have been a couple of problems, and I resolved one or two of them when I started indiscriminately swapping out ESC's and motors. (I lost patience.)
In any case, now I have all new parts and using the same Cleanflight settings I was using before this problem showed up.
I think it may have something to do with the fact that my ship hovers at a very low throttle rate? Please take a look at the logs and let me know if you have ANY ideas. View attachment CLI dump.txt View attachment cleanflight_backup_6.11.2015.20.1.txt
