The LAP COUNTER USB, successor to the well known and popular LAP COUNTER, is a resonably priced lap-counting-system for RC-cars of all scales. It has been espacially developed and is applicable for use in mini-RC-cars of 1:18, 1:20 and 1:27(Mini-Z) scale.

Now even easier to install and use than ever before!


  Lap-counting-system for RC-models of all scales
   Suitable for in- and outdoor tracks
  Any number of vehicles can be counted at the same time
  Personal transponder with unique ID number
  Extremely small and leightweight transponder (12x16x7mm @ 3g)
  Thanks to the new USB HID technology no drivers are needed
  The power feed of the receiver modules/loop now works through the USB port
  No additional power feed via external power supply is needed
  Software for all common Windows operating systems


With the extremly small and leightweight transponder a modelcar owns a worldwide unique ID number. If a car equipped with it crosses the start/finish line, the transponder signal with the ID number will be recognized and processed by the receiver-module in the loop bridge. 

The lap-counting-system can process any number of transponders at the same time, not depending on the number of receiver-modules used on the loop-bridge. The number of receiver-modules much more depends on the width of the track under the bridge. The provided software, when installed on a PC, can be used for practice runs right away.

Mounting the Transponder

The mounting spot for the transponder should be chosen in a way that it can transmit through the windshield without being blocked.

Mounting the Receiver Module

The receiver-module and the transponder work with infrared-sensors. The receiver-modules can be expanded to any number with easy plug & play. This way the system can be adapted to any track width. A receiver-module should be placed every 30cm, with a distance of 15cm on the edge.

Lap-Timing- Software

RCM Beginners: Software for easy race completion
With RCM Beginners You can start a race with multiple drivers without creating groups up front. As soon as the drivers are recognized by lap-counting they are identified by the transponder. The transponder ID can be replaced with the name of the driver during the race and in the future the race result will be displayed with the name. After the race finish a lap-counting-sheet can be printed which can also be saved.


● registers the transponder automatically
● a transponder can be assigned to a name
● race duration adjustable
● group start or single start
● laps-and-time or best-time-results
● starting and ending the race

RCM Online Easy: practice software
RCM Online Easy recognizes every driver equipped with a personal transponder. RCM Online Easy records all lap times by transponder ID, which can be printed out by the driver after his practice. After the printout the data is released and not displayed anymore.

RCM Online Easy will be configured to autostart when the PC is turned on. From there on it keeps recording lap times aroun the clock respectively until a timed PC shutdown. This makes practice on an unmonitored track possible and the drivers can access the performance data of their skills.
