Mikrokopter MK Yaw Problems.

[smartaerials]

Hi !
Lately I'm having 90 yaw spins and then it spins back!!
I using a Dodecacopter, Hexa coaxial, it has been really stable till now but something seams to be failing...
Basic checks done/all motors spining in right direction/all props are tight...
Any tips wellcome!

how is it all wired up? MK's will spin like that when the FC is being starved of electricity. it's like a built in battery warning, when you goose the throttle if the heli spins a bit the batteries are fading.

it could be other stuff but that's one possibility, especially if it's happening at the end of your flights.
