ah i think i get what your getting at now, you mean because the arms were pointing up originally when i hit a bump because of the way the arms move in an ark it would keep the shaft length the same? where as now it has to go from pointing down to straight to up it will effectively lengthen the shaft?
if thats what your getting at i see what you mean and its not something i had actually concidered, if i do get problems with that then i think im going to make adjustable arms anyway so i can just wind them in a little
