How it works ?


Does the LapMonitor support multiple cars passing side by side ?

Yes it works, here are videos that shows car passing side by side:

What is the difference between LapMonitor Club starting kit and Training kit ?

All LapMonitor are identical. The only difference is that LapMonitor training kit includes a transponder and Club starting kit doesn't

What is the difference between Molex and JR transponder ?

Molex and JR transponder types are identical except the connector 

Which connector type should I choose for my transponder ?

The transponder with JR connector can be powered directly by your receiver

The transponder with the Molex connector can be powered by 

  • a 1S/2S LiPo battery with 2 PIN Molex 51005 connector
  • your car/motorbike receiver using the Molex to JR adapter

For 1:8 IC, we recommend  the transponder with Molex connector that very versatile and fast to install on the car body
