I doubt the actual switch comes through the chassis more than 1mm and with the width of the velcro etc, i doubt it would be knocked, its angled forwards as well so that part of the chassis could never hit the ground inless he ripped the wishbone off, but its game over then anyway.
I think the car looks ace!!
Chazz: Why does he spend so long putting the shell on, its not like you could put it on backwards or anything
