Probably no. The engine workings are basically identical to RC plane engines (except the large cooling head on a car motor, which is no big deal.) However, you probably won't have the right surface to mount the prop not to mention the crank might be a bit short. If you can find a thrust washer that will fit the engine, then it might be useable. The thrust washer is a must to keep load off the bearing or case housing. While it may "work" to jamb the prop between two nuts which is what I think you ment, I'd consider this extremely dangerous. Without the thrust washer, you are much better of just getting a RC engine that was designed for aircraft. Cheers

Even if you can attach a prop to the engine and keep it on, it still won't work. Car engines are ported for much higher RPM, which means they make jack squat for power at lower RPM. With the size prop you'll need to fly your plane properly, you'll be so down on power the plane may not even fly at all. An aircraft glow engine in this size is not expensive, so get what you really need.

I tried one, the drive washer was a bit of a problem, as was fitting an rc carb (no big deal in this case) The thread is a bit short, so a stepped nut is needed, usually, and a drilled prop to fit. The timing is fine on the Axial, kind of tame for a pipe even. Got a Picco .05 P0 on the way maybe if I can work out the weak crank. The Axial, I cut off the threaded portion, and softened the crank, drilled and tapped it 10-32. 1/4" - 28 looked like it would weaken the bearing area. I am still looking for a cheap Novarossi .28 to somehow sneak into the house. I could buy a new airplane type reasonably now too ($160), but they used to be $400.
