Yeah, definitely the problem...
although, my rotor head was brand new the last time i crashed, so it couldn't have been the problem before. i was flying wooden blades that had been in a crash before, though, and lost uneven amounts of their plastic coating. i'm convinced that the crash was due to unbalanced blades, or poor tracking before.
It was a mess;
I'm going to order whatever parts i need and hopefully get it fixed this weekend. Ill post a (hopefully) success video
Thanks everyone!
