Nice planes 150flyer. It looks like your SR-41 has a Tower Hobbies muffler on it. How does the 55 like it, and it is much different than the stock muffler?
Huge difference with the Ultra Thrust. Runs as reliably as the stock muffler but tends to go from idle to full power without much mid range. That's OK because the plane I'm using it on is built for speed. I did mix some throttle curve into the radio to help improve controlling the mid range.
