Just did flight 300. Feel like one of the warriors from the movie. I oiled the motor every 5 flights and put tri-flo in certain spot every so often, did boto lube on the thrust bearings at flight 250 or 275. Is there anything I should do pretty soon? It is flying pretty great still, but when I spoke to Rich L. he changed the bearings on his E7 after 370 something flights. Just wondering if I need to do anything like that, even though it is flying better than when it was brand new.
