quark glitch?

[zeropointbug]

Try running it on NiMH mode, just to see if that works?

But, I also think it might be your radio... I was using stock radio and i had the weirdest glitches ever, and like you said, I could recreate them.

Try to use race mode without safe mode.
I solve the same kind of problem with this setup.
It could be some kind of glitch to cause the problem.
However, I burn my esc with wrong polarity after I found the solution.
Pretty sad.
