I just picked up the bariicade remote control car after seeing it in the cool stuff thread (i.e. free pr for the toy industry) and it's super cool. but seeing all the little chintzy-looking mods in the store got me wondering--how could this stuff possibly be any good? I was wondering particularly about the motor/gear upgrade and the steering/control arm upgrades. do they work? oh, and if anyone's gotten the barricade light upgrade, how is it?
