Hi Dave....sounds like you've got a great plan! We are using the Slot Dragon timing system on our 1/32 scale 1,000 foot drag track and love it. In one race we even had identical ETs, right down to 1/1000 of a second. The entire track was cut from a single sheet of 3/4 inch, good one side, fir plywood, by ripping five pieces four inches wide, and the remaining into many pieces two inches wide. When assembled, we had five sections that when joined together, gave us a total length of fourty feet. We used four pin trailer connectors to couple the sections electrically.So whatcha think of my plan? Any ideas?
For stopping the cars, we use reverse polarity of the conductors past the finish line, at reduced voltage. In most cases, the cars come to a stop before reaching the "catch basket", which is nothing more than a cardboard box, filled with cut up foam bits about the size of ice cubes! We've found this method to be very reliable and no harm comes to the cars. I'd be more than happy to answer any more specific questions on our track construction that you may have.
