well....I did have an awesome idea, but, now apparently I can't find the sources I was looking at.
Dana60 IFS front diff, Dana60 Rear axle, custom long travel arms and CV shafts for the front, and a double triangulated rear with coilovers mounted in a very "creative" manner. I won't be giving away details on that part, just, well, trust that I've fully tested the design on scale crawlers and there was less than 2mm of "slop" which didn't effect a 40lb 1/6th scale RC crawler screaming 75mph down the road, absolutely zero movement other than when I'd tell it to steer.
once I find links for the parts, I'll post em up....but, the rear suspension setup, she shall remain secret until which time I make it happen
