I've got no problem with your post except I think your comment about "training wheels" was a little offbase. I said 30% is all I have run in my YS 4 strokes. Twenty years ago I flew Formula 1 with a highly modified ST 40 in a Little Toni and used up to 70% Nitro.
Let me assure you the 2 strokes gain just as much from an extra tip of the nitro bottle as the 4 strokes.
Thinking about past Pylon Racing make me think of a similar comparison. What you are saying is like saying you could put a YS53 on a Preditor, tip the nitro and go faster than a Nelson or Jett 40 on the same plane. But remember the Nelson or Jett can also run the nitro.
Due to noise, looks, acceleration and other factors I'm probably not aware of, I'm sure if I were to get into Warbird Pylon, I'd probably go with YS 4 stroke myself.
I still think my statements about straight line speed are correct even to the point I'd be willing to wager my money on them.
Guess we'll have to agree to disagree
