Engine for Stewart Headwind?

[Erik Snyman]

The part I like about the maximizer is it maximizes the surface area for the prop to seat against. If you ever taken a wooden prop off a plane and noticed the wood looks black or burnt where it touches the mounting flange.......that's not good.

I know it's considered old fashion and inefficient, but man, that row of v-belts just "does" it for me. Inspires confidence....Yes, I know..
