Select engine(s) if had to replace bearins in less than a year
How many have had to replace the bearings in these two engines after very little run time on the engine? We fly these engines a lot at our field. We even have T-34 races with the 46. we have had 6 or 7 engines go bad because of the bearings. well with in the warranity. We send them in to hobbico services and always get them back with a reapir bill of around 100 dollars. They allways have two lines they use on the repai bills. "You injested something" or " there was rust on the bearings". our Club has about 140 members and around 30 that fly every weekend and around 10 that fly everyday. We dont run these engines very hard. Usally a 10x7 APC on the stock muffler. they turn right around 14,000. some guys follow directions by running the engine out and putting after run in and others includding myself just leave them till the next day when we fly. no more than 24 hours before fly again. We own many other OS engines and the bearings Do Not last very long either.
Any way we are getting upset that we buy the most expensive "Sport" engine (jett engines are Super sport) and the bearings only last about 1-2 gallons before they crap out well under the warranity. The OS engines run very well and make good power. It is now that we at the club either have to start looking at other engines or buy the OS and put Boca bearings in the engines when new.
Poll: How many have had bearings go out before a normal time ( 1-3 gallons or < 5 hours)
