Dave, I did get the pumper. Bought it from Tower because they offer a discount if you spend over a certain amount of money. It's supposed to be some newer design or something. I also bought the OS mount that goes with it so I wouldn't be wasting time trying to make the engine fit with the supplied mount. Bought a Dave Brown spinner and a pilot which should look very nice. I don't know why people are running they're four stokes inverted instead of on there sides. I always seem to have trouble when I mount my four strokes inverted. I guess it's a matter of preference. Hope to have the plane built this week but won't fly her for a some time with the 24 inches of snow we had in Boston last weekend. John

My thought exactly in regards to the Corsair.
