Is it just me, or does watching that video remind anyone of Crufts in the 'run around the obstacle course' bit?
I'm liking it though, and Tamiya have recently released the DF03-RA (short wishbone version of the DF-03) which is really cool.
A mild buggy track would be perfect, and then those who don't want to run can stand on a rostrum.
Only thing is, the track would have to be modular, to allow different routes for different stages, 1 lap of the track = 1 stage. Then split the lane in two for the SSS with two cars at once.
It'd be ace.
