RE: First Airplane engine
I have the TT Pro .46 and have had the same results. I am using the stock muffler and it works great for me. It will be greatfor a student and after training it provides plenty of power to have fun with. Get an Alpha .40 and put that engine on it. Thats a perfect combination. I finished training and that engine has the power to fly circles around our field inverted until it runs out of fuel. It is a very reliable engine.
