Here is a place where you can buy all of the parts for the Stihl 090 chainsaw engine for it looks like 500 or 600 bucks. At 150 hp/liter this engine, which is 136.8cc, would potentially be 20.52 hp. Several engines, like the Biboxter twin and Herbrandson twin drone engines, are based on the Stihl 090 cylinders. It should be at least a 15 hp engine, good for a Skypup.

Here's a Biboxter, approx. 30 hp:
