Chassis:
HPI RS12G.
*This chassis seems to be a long wheel base type (like the
YOKOMO chassis) but a stiffer, 2.0mm (RS12G) versus
1.95mm (Yokomo SP) and it is stronger around the battery area.

The
ASSOCIATED is 2.1mm.
The
HPI chassis has also a wider front track as the
YOKOMO one.
Motor pod lower plate:
YOKOMO 2001 version (same as SSG one but in black).
