HELPFUL RACING TIPS
- Always reset the FLAG into the START SENSOR and replace the COLLISION BLOCKS over the FINISH SENSORS before resetting the display to prepare for the next race.
- If the TIMESTOPPER behaves erroneously, check the power connection.
- Use the TIMESTOPPER to test the repeatability of your car's race times.   When evaluating the effect of a modification or tweak of alignment to your car, always be sure to get more than one race time recorded to show its average effect.   Sometimes the race time of your car can vary noticeably because the inside edges of the wheels bump into the sides of the track's guide rail differently with each race.   So don't jump to conclusions about the success or failure of a modification on the basis of just a single race time.   Instead, take several race times and average them.
- Try modifying your car's body shape, surface smoothness, weight distribution, wheel lubrication, wheel separation, wheel smoothness and wheel alignment for best results.
- When modifying your car and testing it for improved race times, races can be run on a short 6-foot track almost as effectively as on a full-length 32-foot track.
- Most importantly to good car performance is that the car be a full 5 oz. in weight, that its wheel axles be aligned for parallelism, and that its wheel axles be well lubricated with graphite.
- On a 32-foot track with only the first two sections sloped and the last two sections horizontal, with the starting line approximately 5 feet above the track section having the finish line, cars will reach approximately 10 miles/hour at the finish line.   Since TIMESTOPPER times to 1/1000 second, a difference in time of 1/1000 second will represent approximately 4.5mm or 0.177" in spacing at the finish line.   A time difference between cars of between 0.005 and 0.006 sec. represents a separation at the finish line of about 1".
