My son, daughter and I have all had a car race on a homemade six lane wooden track that is 57' long. The program uses the best five times and we had 22.15, 21.0222 and 21.1581 combined times for five races. My son had the fastest time of the three with a 3/4" cog. The wheels were hand selected to roll without wobble from the best that we had and they were sanded a little bit to make them smooth. The axles were filed to remove burs and sanded up to 1500 grit. The cars all tracked straight.
My daughter had a 1/2" cog with 2 oz behind the rear axle and 22.1581 time for five races. I'm guessing her car was slower because of the long 57' track. What I had read online indicated that this should be a quick setup, however this is likely on a shorter aluminum track.
My sons car took first in his den and third overall. Will his car be more competitive at regionals on a 42' best track with the 3/4" cog and 3.66 oz of tungsten weights?
What can we do to make the fastest times on a wooden 57' track next year?
