The first Futaba surface system with telemetry! Built on the success of the first radio ever to win the coveted "Basher-approved" award from BigSquidRC.com, the 4PLS adds the ability to read and display four critical racing data as you drive. You can also record them for later reference.Telemetry is the biggest racing advantage the 4PLS offers. Others include user updatable software, 40-model memory, and more — all at the same affordable price as the original 4PL!
