I have a new (5 flights now) E Flite Power 25 front mounted in a retrofitted Legacy that I built back in 2001 and was originally powered by a Saito. I am using the new (thick hub) APC 12/6E prop, a CC Phoenix ICE 50 Lite, Hubin 2A w/rpm set, and a 3600 mah battery. Anyway, originally 9500 rpm would not fly the airplane well enough to do any maneuvers (over 7 second laps on 65' eyelet to eyelet lines). I have been tweaking the pitch of the prop between flights, but the last flight was still over 6 seconds. Energy used on the last (best) flight was still only 1508 mah - 5 min 30 seconds flight duration. Is it possible the ESC isn't detecting rpm properly and I am not turning the set rpm? (I admit I have not checked this with my tach.)
Anyway, when I removed the prop to repitch it for the third time, I noticed the motor had some end play (not side slop or runout). Is this normal? If not, what happened in those 5 flights? Bearings go already?
