A friend had a GP ElectriCub that he converted to glow. It'd creep around nice and slowly, having something like a 52" wing with an OS .10fp on the nose. It was nice and light, and quite relaxing to fly. His brother built a Cub off the same plans, and put a .25 in the nose. He'd built it a bit heavier, and it was a fun plane to watch. After its demise he built another, this time beefing up the structure a bit more and putting an OS .46fx in the nose for some reason. What a dog. Took off in 10 feet, but with all the extra weight the stall speed was so high it was awful to land. That particular Cub didn't last long.

Not that there's any real correlation, but that first Cub last 12 years, the second a couple of seasons, and the third a couple of agrivating months.
