pipe question
I have a Rossi R65 and gonna use a 11x8 prop on it... got a GP Revolver plane... I need to get into the 16K RPM range... I am gonna fly it fast only and look good while doing so... I have seen the plane do 159mph with an electric and 129 with a 55AX... is there an OS muffler which I can use with the Rossi to give me those RPM's? I only have the engine...
