Well I can't understand why anything that is rubber band powered can't be allowed under the PPP program. As long as there is no wet type engine in the plane and it meets the weight restrictions and speed restrictions then it should be allowed under the PPP program.
I don't ever see them allowing wet powered airplanes under the program simply because of the fuel.
I agree that some gear boxes are noisy on some models but I have seen some gearboxs that run almost whisper guiet. Not guite as quiet as an outrunner but still pretty quiet.
Rubber powered aircraft ARE allowed under the PPP, they just have to be RC or control line, no FF planes allowed.
