RE: Looking for Great Planes Ultra Sport 1000 kit
tschuy, I, too, have an US1000 which I think will be my next build. I have a Saito 125 which I think would be a great engine for the US1000. A lot of people say put a 1.80 on it and I'm sure it would be a great sized engine. But I would bet the four-stroke Saito 125 would do it justice. Like you, I have been looking at some gas motors but weight and size issues always come to mind. I hate feeding $18-$20 glow fuel to the plane, but I haven't found a good gasser choice yet.
