bobby,
If you like the way the engine sounds, screaming along at RPM's way over what the engine was designed to run at, and you don't mind replacing your engines every 20 or 30 hours of running, keep using the 10 X 4.
First of all, I'm not stupid enough to run the engine until it burns up just because of how the prop sounds.. I was just saying, it sounds great and I liked its performance. Who knows if its revving TOO HIGH or not?? It may just be the pitch of the prop that is making it sound like that.. So until I put a RPM meter on it, its stupid to assume that Im over revving it.

Who doesnt like the sound of their engine when its tuned good at full throttle??

Having said that, I was simply asking is a 10x4 prop too small, which many have answered yes. I'm trying to find a happy medium.. I'm having foaming problems with an 11x6 (which I dont know why. It may simply me I bought a couple props out of a bad batch). So I guess that means trying a 10x6 or 11x5.

For those willing to give advice, is there a website that has prop tutorials?? Like which prop is recommended for what size motor and what are the advantages and disadvantages to each size??
