The parts plane I picked up a couple months ago had an Eclipse aviation retract motor on it, I did a drawing number on it and came up with something from WWII but did not mention what plane it was off of? Has anyone else used this on theirs and what was the pro's and con's of it besides weight? The plane that it came off of had gear failure, looked as if gear was not locked down before landing and taking the gear out of it. Thanks for any comments Joe.
