No im not considering changing the prop, it doesnt make sense, I cant find a power curve for my motor, so thats out of the question... havent found a leaman user group either... no one likes them that much.... the prop can be adjusted on the hard for a different pitch setting. once the electrics are in then I can re calibrate the prop.
