I am not familiar with the kit. Please give me some specifications to work with. But in any case I will only recommend a 4 blade prop, if you back me up against the wall. The reason being, because they are very inefficient. In general, performance really stinks with them. You will always be better off turning a 2 blade prop in scale diameter. Remember, you cant see the blades when they are turning, but you can see the prop arc. when it is sitting on the ground just put on a dummy prop.

The RCV 90-SP would be the perfect engine, turning a Zinger 18x14 two blade cut down to 16 inches. This should give you enough ground clearance and enough prop area to move the airplane very nicely. The engine would be turning in the mid 4000 range with this prop and the correct fuel.
Thank You
