I have been playing around with various props on my 7 pound 4 ounce World Models Spitfire, it has a YS FZ115WS running on 30%. I currently have a 13.5 X 13.5 APC turning around 9800 RPM. I am hoping to run in the silver class, and I really don't want to use a higher nitro content to save on glow plugs, and wear and tear on the YS.
Any additional thoughts on prop choices would be greatly appreciated.
Thanks,
Mike
