Racing transponder service
Vintage racers will want to know about the racing transponder battery service from Texas-based Mueller & Sons Toy Company. AHRMA racers can opt to rent or own required MyLaps transponders, but prior to the new service from Mueller & Sons, the only battery replacement outfit we knew of was in Australia, so getting batteries replaced drove many to rent. Mueller & Sons says replacement starts at $55 depending on battery type, with a two-week turnaround. MC
