I built a GP .60 Cub and put a Saito .91 on it. It looks great and sounds even better. I haven't put floats on it, but plan to. I think the .91 should be plenty of power, but don't know for sure. BTW, I didn't bother trying to use the plastic cowl that comes with the kit. I ordered a fiberglass one from Stan's Fibertech and am very pleased with it. I did use the plastic cowl to make a template to cut out the engine hole for my fiberglass cowl.

Matt-

I would consider a .70 4-stroke for that plane. Others may have other thoughts.
