The 410.3 is for large outdoor Tracks and thus built more durable. The 410.3 is discontinued but a Replacement is on it's way, but no ETA at this time, he wouldn't go into more details, just...soon.
I suspect it is a slightly converted EB48 2.1...maybe different Hubs so a 12mm SCT wheel will mount up, and a few other bits...I had a EB48 2.0, it was a good Chassis, just a Little more Fiddly when compared to the old EB48.2 to EB48.4 and 48SL and SCT410.3.

Tekno has a good business model, build Chassis that share a lot of parts, keeps R&D costs low, manufacturing costs low, and for a Driver, ease of maintenance and parts supply...Just wish they would Expand and make a 2wd Buggy and 2wd SCT
