I'd like to add a gas model to my airplane inventory. Prefer to stay on the small side of gas. Completed fuse length needs to be no more than 72" (Airplane, motor, spinner) due to vehicle size. Prefer and ARF, can be scale(ish) edge, extra, yak.... or can be a profile like an OMP. I've read till I'm totally confused on small gas engines. I do want power to do 3D. Engine needs to be realiable. I've fitzd YS's 140's till it's no fun anymore.
