I think I was supposed to get a set of those shoes, but never did.....we always just rotated the can some when I was a kid with the ERP.......we tried it once with brood when Adrian made a big deal about how he was gonna DQ racers at nats if the gauss meter showed them timing zapped.......all our testing showed the magnet died off too easy from heat......
I guess I need to go silver cans.......those with crawler motors, maybe I can become a millionaire again
