That forum link answered my Q. It also gave me assurance that most things are what they should be. Since I have an inverted fly horizontal. That also is inline with the thrust. I conclude most of my original problem is the drag produced by the forward hull. that now eliminated. The additional stabilator travel should be whats needed.
On a side note. I reviewed one of my video .taking note of my own statement that I had once used a 3 inch spacer that performed well and had removed it in favor of the 2 inch for no apparent reason,other than my dislike to install it. [my pivot for transit was resisting that much because it was not made for that setting]
AS for the hull curve I can not prove what I said but it seems to force the plane up on step after the initial bow wave develops and the nose is high. Without it, it just bogs down in the wave.
