Here's our prototype on a TechDAS Air Force III
in all its messy glory. How does our new arm compare to earlier flexure-based prototypes, and to the ball bearings ones?
It clearly isn't bad at all. I would say it's superior to a Prototype 5
with conventional bearings. The addictive smoothness that appears once you get rid of rolling bearings is there. However, it loses in dynamics to Flexure Prototype 2
. Is the Riverhawk pivot to blame?
I don't think so. Remember, we've also changed the way armtube is held in the central part — from clamping to fixing it with a stopper screw. As the measurements above showed, it's a much less rigid connection. While it might be acceptable with softer armtubes, a thick-walled stainless steel one has exposed its limitations. I would try not to use such connections in the future.
