The benefit of the floating rear suspension is in that it generates a lot of rear traction in general.
Paul,
I remember the Lynx...had friends running it. That was a very interesting design but was unfortunately very heavy. I found the PB Sizzler a much cleaner design but it was a pain in the butt to keep all 5 of the links in proper adjustment.
I guess I gotta get my ol Solid Works goin again and start working on mine now with all these new scratch builds inspiring me
