just a quick update on mine.......

found the problem with my "limited" vertical........bad rear crankshaft bearing. took it out a couple weeks ago and the motor sounded like ....... i don't know what. shut it down and turned the prop, there was a scrub and grind in it.

brought it home and found the cage that keeps the balls spaced out was completely gone. nothing but small pieces (app 1/8 by 1/4 or less) left. got new bearings from a bearing supply house locally and ....... WOW talk about a difference.... it flies lilke a different plane. i now have enough to go as high as i dare. the 1.20 does this plane wonders.
