RE: [CAD_CAM_EDM_DRO] Re: Counterbalancing & Rong-Fu RF-45 Project

I hope the MSC versions work better than automotive ones. Any car I've
owned with a hatch back has had at least one spring fail so that the hatch
won't stay up, so I had to carry a stick to prop it up. I know several
people who preferred a stick to a $60+ price tag.
