I still have my plane in the box. I can't decide how I want to power it. The airframe was heavier than I expected (fiberglass).
I have a Zenoah G38 in mine. I think any of the 40cc gassers would be fine in it. If wanting a 2s , a os 1.60 is perfect as well as a Saito 180. Note that this plane is quite tail heavy so a fair amount of ballast is needed up front when using a light engine.
A Moki 2.10 would make it fly like a foamy. check out this thread. I put a link of a kid flying it with an overpowered engine.. It's pretty awesome.
Good luck on the build.. It's one pretty plane.
Later,
Dan
