Im getting a lt-25 and am wondering what engine to buy for it. I just like doing some maneuvers and sport flying so I think I want the midle of the road engine size for this plane.

P.S. I know OS engines has come out with a wankel rotory engine in about size .35 it would be nice but I cant find any prices for it (or any where thats saleing it) help please??

thanks all!!!
