I used to run a TC3, but sold it
, so I thought I'd make recommendations before the chassis goes into full production.
Firstly, you may want to move the battery position as close as possible to the center shaft. I milled out (dremelled out
) my old TC3's chassis to get the battery closer to the center, and this was a popular modification a while ago when I ran it. It puts the weight close to the centerline making for great transitional handling without the use of stiffer springs. However, the milling out was a lot of work and made the chassis flex as you removed half of the center "spine", which brings me to my second point.
Double deck cars tend to flex, which is not desirable among many drivers, on carpet especially. Many people in the US will want to run your new chassis on carpet, and so, if you can design it to be as rigid as the tub chassis, this would be a big plus and a good selling point.
