    Hey guys, I currently have a ProSimu 2dof using SCN6-40 100mm actuators. I'm going to build a 4dof using SCN6-60 200mm actuators.

    The -40s have a speed of 200mm/s, but the new 60s have a speed of 100mm/sec.

    By my thinking, I will match that speed in longitudinal by going to 4dof, because I'll be accelerating up on one end and down on the other now, thus doubling the perceived speed.

    In roll however, I will be losing speed. By my thinking, as I move the actuators inboard, it will increase the perceived speed, while increasing the lbf, right?

    As per the drawing I'm currently at 35.5" centers on the actuators. How far inboard can I move them? Based on the weight, I should be able to move them in as far as I want?

    Regarding COG and tipping, the actuators will be bolted to a 40" wide sub-frame using HEIMs, so tipping should not be an issue.
