I have an OS 160 on mine. I bought the plan engine and severos all set up the way you see it. Got a good deal on it. The 160 does a very good job on it. Very happy with it.
There is a lot of engines that would be fine on this plane. If I was to go out and get a new one for this it would be a BIG 4-stroke. But that's just me
