Anthony, I
ve got the Al master's Do 335, and I can't remember who the Wildcat [plans were drawn by, they sre for a .60-.90 size engine,, I bought the plans on RCU.
maybe if you have some time later we can talk via phone and discuss
502.718.1614.
I saw the devestator kit on kit cuters, but it doesn't say who did the plans.
