For just 5 more ounces Brillelli has a 36cc engine.

I have a Toro 25 that I sent to Scott.
It is a real winner 18x6 at 8000 rpm.
I have it in a Great Planes Tiger Moth.
It doesn't really need a run way.
I have the Brillelli 36GT and I am turning an APC 18 X 6W @ 8,500rpm's and it is still getting better and better, I also have a CRRC Pro GF26I that I turn the same APC 18 X 6W @ 8,050 and turning a APC 17 X 6 @ 9,350 rpm, and the CRRC 26cc was @ the door for under $200.00 with a pitts muffler.
