I think the flex of the SSG chassis is brought out in carpet racing with foams. The amount of grip you get on a high-bite track is huge, and it takes a very, very strong chassis to stop flexing. The Losi and Associated cars seem to do very well in this setting, while the Yokomos, Schumachers and X-Rays seem to have more difficulty in staying consistent. This definitely goes along with the results we saw at the ROAR Nationals (which is also where Chris was using the multi-deck MR4TC SSG car).
