Further info

Personal transponders have become very popular with remote control model car racers over recent years because of convenience and prices becoming more affordable. They will usually work forever and are internally very robust. The only real weakness is the power lead which plugs into the radio receiver. The original AMBrc DP power lead was more susceptible to becoming brittle and breaking off at the body of the transponder. Mylaps addressed this weakness with the introduction of the Mylaps RC4 transponder by using a more resilient type of wire coating. However this wire will still break due to accidental impact or mishandling. So be careful with them and to save extra handling which puts wear on the lead, many racers opt to install a transponder in each car. We recommend you do not attempt to replace the lead yourself as most amateur attempts end up killing the transponder. Transponder services stock and sell Mylaps RC4 hybrid transponders with 2 wires and the later RC4 pure transponder with 3 wires.
