MyLaps RC4 Pro transponder

MyLaps have introduced the RC4 Pro, what they claim is the world’s smallest transponder. The RC4 Pro features a shorter 8cm / 3.15in cable, ensuring a perfect fit every time and the pitch-black design gives any RC car that beautiful finish it deserves. The transponder comes in at only 3 grams, making it almost as light as a feather.
