The Twister plans were at least 35 years old that I'd gotten from MAN back in the 70's. The Killer plans were the tiny magazine plans that I took to Kinkos and enlarged (about $5) after doing the math on what the enlarge percentage needed to be, and the Voodoo plans were also enlarged at Kinkos out of an old book of "Kit Plans" that AMA published some time ago.

I put another flight on the Killer a few days ago. This time I ran it on a straight 75/25 methanol/oil mix and it was about as fast as with the 5% nitro fuel. That particular C .35 has beastly compression. I don't remember if I upped it over stock or not. I fitted that engine back in the 70's. I do remember working on the crankshaft fit to loosen it a bit and did a bit of lapping with Lava. I may have eliminated any head gaskets and lapped the head right to the liner.
