I think the advantage of it is the fact that when the swashplate moves down it frees
up the linkages and less binding. Scince we all use positive pitch more than negative
pitch, inturn you will get smoother operation. I have thought about doing to the esmart
head because the hurricane head worked very good that way. I hve flown the same
heli with trailing and leading edge grips. The difference isnt stagering but you do
apritiate the smoothness. Anyway since I have done both I would and think I will again,
setup with the trailing grip linkage.
