RE: Three bladed props vs. two bladed props.
3-blade props are for ground clearance and good looks. i have an electric turbo porter i plan on using a three bladed master on purely for the looks. i don't have any planes that need the additional clearance. altogether i probably have 20 3-blade props of varying sizes. so far used? none. BUT it won't be for long. the turbo porter (running gear) looks to be my christmas present :-)
