RE: Aluminum Bottle Muffler (Pics)
Hello Everyone, very good results with this muffler.
Maintain same RPM´s as the ones obtained with no muffler ......7,500 RPM´s with a 18x6 wood prop.
In terms of noise, it really makes the engine very very quiet......comparable to a muffled 120 size commercial glow engine.
Regards.
