Out of curisoity, some of you guys that run rotors on rover stations please
advise what the advantage is. When I am not traveling between grids, I just
drive the truck in a circle to achieve the desired heading.
This even works when I use my tower trailer. I just crank the out rigger jacks
up to clear the ground a couple of inches and slowly make my "rotation". This
lets me have the outriggers there should I need the stability. ( Maybe you guys
are not in places as flat as Florida ) Comments ?
