MYLAPS RC4 Direct Powered 3-Wire RC Racing Transponder 10R120

The MYLAPS RC4 Direct Powered Transponder 10R120 is a compact electronic lap timing device for RC cars racing at tracks equipped with compatible MYLAPS RC4 timing systems. Powered directly from a spare receiver port through a standard three-wire servo connector, it provides accurate lap detection without a separate transponder battery.

Features

• MYLAPS RC4 Timing Compatibility: Designed for race circuits using compatible RC4 timing decoders and associated lap scoring software.
• Direct Receiver Power: Connects to a spare receiver channel or battery port using a standard three-wire servo plug, eliminating the need to charge a separate transponder battery.
• Accurate Lap Detection: Magnetic induction communication provides a published code resolution of 1.5ms for competitive RC racing applications.
• Individual Transponder Identification: Uses a unique seven-digit transponder number so race organisers can identify the vehicle and record its laps.
• Additional Timing Data: Compatible RC4 systems can report transponder supply voltage and temperature when the vehicle passes the timing loop.
• Compact Construction: Measures just 16 x 19 x 6mm for installation in space-limited RC racing chassis.
• Lightweight Design: Weighs approximately 4g without the holder, helping minimise additional weight in competition vehicles.
• Wide Operating Voltage Range: Accepts a 3.0–16V DC receiver power supply under the published product specification.
• Low Power Consumption: Draws approximately 14mA at 6V DC.
• Heat-Resistant Wiring: PTFE wire insulation is designed to resist high temperatures and exposure to petrol and nitro fuel.
• Versatile RC Applications: Suitable for compatible electric, nitro and petrol-powered RC racing vehicles.
• Indoor and Outdoor Racing: Supports timing at compatible indoor and outdoor RC circuits.
• Simple Installation: Mounts horizontally and close to the chassis underside, with the manufacturer's recommended maximum height of 15cm above the track.

FAQ

Will the MYLAPS RC4 10R120 work at my local RC racing club? It works with compatible MYLAPS RC4 timing decoders. Older AMBrc2 and RC3 decoders are not supported unless the venue has installed compatible RC4 decoding equipment or upgrades. OZRC recommends confirming the track's timing system before purchasing.

Does the MYLAPS 10R120 need its own battery? No. The transponder receives power through its standard three-wire servo plug connected to a suitable spare receiver channel or receiver power port. The receiver must supply power within the transponder's operating voltage range.

Where should the transponder be mounted in an RC car? Mount it horizontally, preferably low in the chassis, no more than 15cm above the track surface. Avoid placing metal or carbon fibre directly between the transponder and the track's timing loop, as these materials can weaken signal detection.

Can the same MYLAPS transponder be used in multiple RC cars? Yes. The transponder can be moved between vehicles with suitable power connections and mounting arrangements. Its identification number remains the same, so race registration and timing setup should be checked whenever changing vehicles.

Important Notes

• The MYLAPS RC4 10R120 is a three-wire transponder intended for compatible RC4 timing decoders. It is not a universal replacement for older AMB or RC3 transponders.
• Check compatibility with the racing club's decoder and firmware before purchasing. Some clubs may require particular transponder types or registration procedures.
• A powered receiver connection is required. This product does not contain a standalone rechargeable battery.
• Observe the 3.0–16V DC operating voltage specification and correct servo connector polarity.
• Mount the transponder securely in a horizontal orientation and within 15cm of the track surface.
• Do not position metal or carbon fibre directly beneath the transponder, as signal detection can be reduced.
• For reliable race scoring, register the correct seven-digit transponder number with the race organiser.
• The maximum published detection speed is 120km/h. Confirm suitability with the timing operator for faster vehicles.
• Different retailer packages may include a separate mounting holder or spare cable. These accessories are not guaranteed in this listing unless confirmed against the actual stock package.
• Receiver, RC vehicle and track timing equipment are not included.
