sdg666, Ijust recovered my slowpoke arf. Had a Evolution 45(trainer motor). Probably a couple hundred flights on it. Just got a gift after i recovered it, a Evolution 60! ( Thanks to fatherinlaw). Couldn't decide what to do with it though. Thought about putting it in my twist ,but think it would barely fit + os46 seems just fine in there. The slowpoke had to have nose weight with the 45. Soo im thinking it will balance close with the 60. Will have to check balance,prop clearance,throws and will be good to go. Might test fly this weekend, if it doesn't snow to much, or get ski's. Ive overpowered a couple of my planes with this motor and have been pleased: Lt-40, Sig 1/5 cub.will try to post pics. i usually just read on here.
