RE: "Thunder Tiger engine.
One of the last glow engines I owned was a TT.46. It is a powerful, easy handling engine. It always started right up and ran through the tank. I used APC 10x6 and 11x5 and 11x6 props with it. It was installed in a Tiger .40. The plane was fast and flew beautifully. The carb is easy to adjust as it is a two needle carb. It's on a par with an OS.46, but less expensive.
