Ken,

I had mine on a Tower Uproar for a while and now it is in a .30 sized Waco bi-plane. The engine has the power of a decent .40. It drinks fuel like a .60. The idle is a little high and it does tend to overheat with synthetic oils. It is a quiet engine and very reliable. The price is the only reason I don't have a few more of these. I would love to build a twin with the Wankel.
