[QUOTE="Bebop, post: 716410, member: 5925"] Only differences in terms of function are going to be : 1) the volume of each ram chambers being identical left to right (in a DE ram) or different left to right (in a SE ram). This will affect the speed the shaft moves in and out for a given steering input and the number of turns the orbital has to be turned in order to move the shaft a certain set distance. 2) the surface of the ram piston being identical left to right (in a DE ram) or different left to right (in a SE ram). This will affect the force the ram is able to make. Actually a SE ram will have a greater force in one direction (the one pushing the shaft out will be "stronger") compared to the DE which will have the same force on both sides (which is comparable to a SE pushing the shaft end in). In order for your steering setup to have improved the speed of the turning response, the big difference had to be a different volume in the ram. It makes complete sense, especially on the non-shaft side. By personal experience, I can recommend going DE ram if any kind of fast travel speed will be achieved, but for a strict crawler a SE ram will be just fine IMO. My buggy is going to be SE for now because that's what I've got. And I'm not too worried about that. EDIT : Also, know that some unequal volume orbitals exist in order to have the same number of turns and speed in both directions with a SE ram. [/QUOTE]
