45cc Overbore (52cc) Engine Ordered For My Ultimate Biplane
I guess I kind of took a small leap of faith here in ordering a gas engine for my Ultimate Biplane and I say leap of faith because first, I don’t know much about gas engines/models, secondly, I ordered the cheapest engine I could find that was plenty big to power my plane and third, it’s coming from Hong Kong. I ordered a (Turnigy) TGY52, which is their 45cc engine bored out to 52cc. I found the engine at www.HobbyKing.com, check it out, they have great prices on gas engines.
