I am recovering a Kadet Senior with a specific scheme in mind. Since I don't want to get a lot of oil on it from a glow engine, I decided to use a RCG 15cc gas engine. I considered converting it to electric, but with my covering scheme, I want the gas engine noise. I was telling my plans to a friend and he was concerned about the vibration from a gas engine compared to a glow. He thought the airframe would vibrate apart. Has anyone used a gas engine on a Senior? Do I need to beef it up to handle the engine. The engine is heavier than a glow, but I will move the servo's to the tail and other balancing tricks to get it balanced out correctly.

Thanks
