One of my customers sent me a photo of a modified large scale muffler on his plane. The model number is our SMQ-2K. He added a cheap 2" aluminum spinner to the front with some JB weld. he also used a couple of copper sweat elbows, and flange plate. He than repainted to match his trim. It is not only neat looking, but very quiet. The engine is an O.S. 1.60 FX.
