    I hear you Bruce. I tuned my P car sans mag. Glued the mag in, MM-ed the car, and ran about a dozen laps at warp speed. Weird.

      I feel that this rule is not completely thought out, as there is no rule requiring those of us who made chassis out of conductive materials to cover them up.

        Any track owner can refuse to run a car if it causes electrical problems. I do agree that a brass plate chassis poses a short-circuit risk which is almost identical, or worse than the risk posed by a magnet. As you say, we could have done better with that rule. But no one caught it in time. My own brass plate car which is still in development for RAA has a piece of tape on the part of the chassis which might short out on the hill at HSARC, which is known to cause high-centering on cars with less that 1/16" clearance.

          Brass chassis

          The WPR Can Am cars did not have any problems at HSARC and the clearance must have been down from 1/16 as the cars had done 12 races before HSARC.

            Actually, Phil, the cars that bottomed did have less than 1/16" clearance, which is how I know the ground clearance rule was ignored. That rule later disappeared from RAA.
