Dick - the whole idea of going with the ST2300 on this is simple ECONOMY. There just is NOT a more cost effective, powerful, reliable powerplant for this kind of a/c out there. I'll probably turn a 17 x 6 or 17 x7, unless it proves to be just too big a disc. At any rate, with the KS canister under the wing, and a Mueller header, the balance won't be too tricky,

I'll run 15%, and sure I'll be putting around at 1/2 throttle or less for sequence work, so fuel economy won't be an issue at all.

I'll put pics and a report when I get her all done.
