27 trophy

[Bill Kemp]

if you have a allison cut done on a trophy would there be any increase in rpm due to less blade area and does anyone know how much of a increase it would be

Mine increased about 100 RPM. I had mine done at performance propeller. However, after a year of running I discovered a crack about a 1" long on the trailing edge of one of the blades on the first trip out this year. The prop ran great up till it start to go deaf!
