Drives very nice. (Spare parts are finally in!)
Building a S411 this week, will be back in a week or so with an update.
Both nice cars, and set up correctly, both drive great!
Each has it's own strong points:
TC6 diffs, have lighter alum outdrives and plastic gears, better case gasket, easy to build.
S411 diff have HD metal gears and steel outdrives, nicer x seal on outdrive shafts, but crappy thin O-ring case seal, and more tricky to build without leaks
TC6 has more adjustment points on steering and camber link, and steering rack has less slop, although
S411 steering works excellent, box stock
Although different, both styles of shocks work excellent.
TC6, easier to adjust track width, with the included arm mounts&shims, but
S411, arm mounts won't slip (which creates arm slop)
TC6.1 roll bars seem nicer with the alum center...but I do not use sway bars on either car.
TC6.1 cost less, and has better instructions and set up tips.
S411 is wicked fast and easy to drive (actually, both are wicked fast and awesome to drive, if set up properly)
Both, great cars to have. I have my tc6.1 set up on foam tires with 10.5 spec, and the S411 on rubber tires, 17.5 boosted.
Still wouldn't give up either car for the other.
