Moding the AFX digital lap counter for weak magnet cars T Jets
Here is a good mod I did to make the AFX lap counter work with the weak T jet magnet cars and it works like a charm!!
Photos shown at bottom.
First I unscrewed the unit and unhooked the counters little board by scraping the plastic holders off that held it down.
next I simply cut the plastic off flush to the box as close as I can ( see photo)
then you take a straight a 15" would be best simply line up the counter board across the bottom
( I lined the back of the sensor board up to the straight beam that goes across the track section)
next with it lined up see where the sensors line up to each of the inside rails on the track bottom and mark the area with a marker where they will set in the track so you know where to grind out there on a angle.
Now that your track is marked grind out the plastic on a angle so the sensor will get lower to the tracks bottom surface ( see photo)
after this is all done simply use CA glue and put some on the track where the board hits and glue the unit to the bottom and let dry ( I also made it more secure by going around the boards edges with goop shoe goo glue to make it hold better.)
Last when all dry use something like a wood or plastic rod and push the sensors down close as possible to the tracks bottom surface as shown in my photo. (a back of a small paint brush will work good) you don't want to use metal or you may crack sensor!
After this set up your counter on your track and enjoy!!
Hope this helps some racers out!
