We have a little bit of familiarity with a slide-drivetrain. We tried one in 2008 but we hard-connected the wheels to the frame and quickly discovered why you absolutely MUST have mechanical compliance to insure all the wheels are on the ground. What they have here appears to be a refinement of their 2010 drivetrain.
Could you expand a bit more on why the hard-connected version didn't work and why the center wheel must be articulated? It seems to me if you just had it dropped enough the hard-connection would work.
