Cheers guys !
I've disassembled the 330 now - as I had to get the KK2 out to see if I could fix it - I can't
One motor is shot too so bit of a bummer.
Arm is bust and all 4 props are broken or unusable.
Don't know what happened really, it all happened a bit quick!
Worried i'll do this again now once the new build of the wood frame is done.
