Herb, what RPM does the RCS 1.40 turn with the 16x8? Sounds like a good engine.

The FPE 1.3 is based on the Echo (Kioritz) 21.2cc engine. The big E letter cast on the cylinder gives it away. My Echo 25.4cc has the same exact letter on it. It's a little weak for a 1.20 aerobat, but I sure dig that cute wrap-around muffler though. I have an Echo blower that has this same engine in it. If some part in the blower ever breaks, I'll liberate the engine in a heartbeat.

The FPE 2.4 at 3lbs, however, looks like a good match for 1.20-1.50 size Extra or Edge. Then again, it's rather pricey.

Still, I like the new G26 the best. It's not priced in the stratosphere like the other small gassers. The weight of it doesn't lend itself well to the all-too-popular 3D stuff, but then again, I'm not a hovering kinda pilot. I happened to think the airfoil on an airplane should be put to work.
