I had and I said a Byron Hellcat with your set up, you can see it in the last Warbirds over Delaware video, Plane was 26lbs, running on the 4.2 Sachs, which Ralph at RC ingnitions got running again after my crash[o:] at warbirds over IN, back to the bird, I got rid of the purrpower put a J&A pits style muffler, turning a 24x10 Menz S at 6300 RPM on the ground. using 50:1 Stihl oil mix. Velocity stack on the carb.

This plane was a hot rod , could keep up with the best of them at warbirds show, even a bit too fast for some pilots I was flying with in formation.

I'll be happy to answer any questions you might have.
