Default RE: Is there a constant speed RC prop?

A couple years back, I purchased a set of plans for a P&W Wasp Jr 1/6 scarle engine. Included is a set of plans for a consant speed prop for that engine. The designer sells carbon fiber blades for the prop, and you can make a 2 or threee blade setup. The prop is a 20" with a 16 pitch at 6000rpm down to a 5 pitch at 3300. This is bigger that any thing I'm flying now but I've been toying with scaleing it down. There is even an option for a hyd cylinder setup to provide an overide on the spring loaded setup with weights. You can see a view of the two blade version here
