well Tim im sorry that you had to get a new case and other parts i guess we all learn from our own mistakes,i've been flying helis for well over 13 years now and most of the time when the a heli crashes it takes out the bearings on the head's main shaft and spindle and other bearings depending on the crash but you should know that the bearings are very critical the least stress on them causes a notchy ball bearing and you're done well at least you figured out the problem,i hate it when things get more complicated then they really are,thanks for the compliments on the plane and thanks for the great ideas on the engine set up i do like the old choke bracket though but the new one is still good
