Hi Everyone,
I am putting together a .60 sized Great Planes Extra 330S. I plan on putting the OS Max 91FX in it. I want to use a Pitts muffler so the model will look better, but I also want all the power the engine can put out at 7000ft. I am considering the Bisson Pitts muffler, but will this muffler (or any pitts muffler for that matter) restrict the power compared to the stock muffler?
Thanks for your help.
