Hey Guys,
Forget what I said about the cnchelicopter.com head parts. They are JUNK! At first I thought my head shake problem was cause by a bend main shaft. I just replaced it and I still had the problem. Upon further investigation, I discovered that the teter toter does not have bearings in it. It is just pined. I replaced it with the stock part and am still having problems. diging a little deeper I have also discovered that the main hub and blade grips are of low quality. One side is not seated as far in as the other and when trying to adjust it, i have found that it binds if the screw is tightened to much. The stock part did not do that. Anyway, I going to see if I can get my money back on these parts.

Sorry for the bad info, just goes to prove, looks aren't everything.
