Double checked pitch curves tonight and actually it is more like +2/3 at mid stick in idle up and +12/13 to -10/11, so just a little off from being equal. It seems like I need to have a longer lower pitch link (the link to the swash on the blade grip). I may try using an adjustable there. I cannot shorten the upper link any more to get more neg pitch. I am still not sure why I now need to have 9/16" from the top of the main shaft instead of 1/2". Have a few pics of current setup.

Another thing that seems out of whack is that when I switch back and forth between norm and idle up, I have to have the throttle one mark towards positive collective for the servos not to move (see pic). At true mid stick the servos move when the switch is flipped.

OK - picture upload is not working???

LHS couldn't figure it out. Just seems like something is different with the geometry for the head.
