CascaBots RoundBot Chassis for Tamiya 70097 twin motor gearbox
I've taken a look at what's out there for the Tamiya 70097 gearbox, and decided to design this chassis :-)
Major design features include a twin deck and parallel I beam construction for rigidity; all moving parts,including the turret mast are inside the diameter of the chassis - nothing protrudes (Frits's request); the internal beams fully support the output shafts from the 70097 - a sorely lacking feature on current chassis... and my personal favorite, an engraved protractor on the top deck. Makes it easy to see and adjust code for turning radius.
Chassis uses a Tamiya 70145 wheel set.
