jollycub- You have to be careful what you read, because not everyone who posts things on the internet actually knows what they are talking about. If you heard from someone who has actually used that engine on that plane and can give some real world feedback to you, then great. But there are way too many guys who know just a little bit about the hobby and will tell you that something will work when they really don't know if it will or not. There is a small grain of truth to the idea that this 15cc gasser is equivalent to a .60 glow engine. The peak horsepower is probably very close, since glow engines make more power for their size than gassers do. But the similarities end there. Your plane was designed to fly with a .60 glow engine, and many have flown them with less. An electric conversion is viable with some woodwork done, but to go gas requires having an airframe that is designed for the weight and the strong vibration of a gas engine. Stop worrying about the glow residue. Unless you are an extreme germophobe or OCD (in which case this isn't the hobby for you) the glow fuel slime simply isn't a big deal. You fly and then wipe the stuff off. It takes 2 minutes to get the plane clean and then it's back into the car with it.
