Thanks for the info on the SYSSA engine sgillmore. I'll take a hard look at their 30cc engine. The price isn't really the determining factor, it's just that I had hoped to fly this US 1000 quite a bit and if I could do it on gas rather than costly glow fuel so much the better. If this SYSSA engine will fit in the nose of the plane and not be too heavy it might just be what I'm looking for.
