In a sport where details matter as much as they do in RC racing, even the slightest modification can make all the difference. Insight into data such as lap times, connected voltage and ambient car temperature can shave seconds off your finish times. RC4 transponders can be used for both indoor and outdoor racing and will perform on just about any surface.

How does it work?

The track you’re racing on has a MYLAPS system installed
at the start and finish line and at intermediate points along the track. The system picks up the signal sent out by the transponder mounted on your car. This signal is analyzed and lap times are measured. The system knows exactly on which lap you are and what your position is. This data is passed on to race officials and published to your personal MYLAPS account. When you drive on a track with a MYLAPS RC4 timing system installed, your account will also show you information about the connected voltage and ambient car temperature.

Easy to set up and maintain
It is easy to get your transponder in and out of your car using the holder that comes with your RC4 package. The holder should be installed at a maximum height of 15 cm (6 inches) above the ground. Transponders need to survive the heat of battle. RC4 transponders are shock and mud-proof and can safely be used for both indoor and outdoor racing. They can even be used for model boat racing. Because they connect to your car’s power output, you don’t have to worry about recharging them. If you use your transponder a lot, it can get dirty over time. Use a soft brush and some lukewarm water to clean it.
