I am using 2 Master Airscrew 9x7 3 blade props on my A-26 wings Mfg. kit. The engines are O.S. LA 40's. It fly's very fast and accelerates very quikly. I want to try a set of the Evolution Power System 3 blade Props which are 10" dia. and a inch wide and give a more scale look. The specs say 9x6 but the overall measurments are as above.

First link is Evolution prop, second is Master Airscrew prop................

Would these props be a radical change in performance or a slight change?

Thanks,

Ed
