Thanks for the input guys. I just did some calculations on motorcalc to see what kind of rpm I will need to fly a 60 size warbird. If I can keep it around 9-10 lbs. I will need on a 14x10 8400 rpms and on a 13x10 8700 rpms. I plan on using gas/glow. With porting is this attainable on this engine?

Thanks
Jim
