RE: What engine for a H9 Cap 232 1.20(1/4 scale)
I was not trying to start a war. I just wanted to point out that as long as weight is within spec, and CG is within spec, gas is possible on a 1/4 scale plane with good results.

PS I do pay attention to experience, then compare it with what is now, and usually a mix of the two is best.
