Does your violent tumble look anything like this?

I initially thought it was VRS, but other pilots who have watched it have suggested power distribution problems, or bad harmonics as the Naza becomes unstable, then over corrects, then over corrects some more, etc., until suddenly you're at zero AGL.

Hi, saw your video and my heli does not act like that, yours looks like its tumbling down, mine looks like it wants to go down but right side up, no violent drops, heres a more torough explanation
1 power on controller, then Power up heli on gps mode
2 wait for satellites and home point save
3 send it off flying, get some j hook and just a little of tbe (not to much)
4 after some fly time, maybe 5 min, jhook is better but notice strange behaviour
5 when flying my phantom and its going fast, whe. I let go of the sticks, it starts stopping by itself but one of the motors looks like it doesnt catch up with the others and makes this flutter movement which looks like its going to fall
6 i bring it in asap and let it hover close to me, while looking at it i noticed that its unstable and it yaws like 5-10 deg to the right, just a little bit
7 i sent it off again, tough close to me, and most every time i yaw, either direction, i get this weird flutter, or sometimes i get this reeeaaally wide yaw and sometimes i get reeeaaly tight yaw in either direction with some flutter, i am afraid of yawing sp? my heli
8 i just fly close to me, i am afraid of loosing it, sometimes i bring it in a do a compass dance which does not help at all
9 when battery empties i try a new one and go thru all steps described
Sana
