Barry: I understand that noise is a big thing at lots of fields. Its bad that so many people make a big deal of things like this but they do there worry about lots of stuff and the things they need to worry about is let go, i am talking mostly of the young kids thats growing up that has no resect for anything because no one makes them mind, Kris is right a prop can help with the noise alot some day someone will help with the muffer thing to pro-zinger has done a good job for me. I fly at four fields and noise is not a problem at them guess we are lucky. may be thr three blade or pro-zinger will help you good luck
