yes driver weight was in the seat, good point.

the infinitely adjustable a arms could put the thrust at 0 but i don't have these, unfortunately or fortunately it is at a good place now, 1/2 turn of 1 heim joint puts the thrust angle at 5 or 7+, about a 7 or 9 deg. swing, can't remember now. with the inboard joints and toe adjustment it gets to be a 3 dimensional slinky.
