Space Derby® Finish Line and Track
This
diagram shows our finish line design in the green, blue and red.
We supply the plans for you to build the frame.
The supports are designed to be adjustable in height and each sensor can be adjusted to be centered on the fishing line used for the space ship track. The sensor wiring and the support design detailed here are made to fit the Space Derby® track described in the Cub Scout leader HOW-TO book. If your Space Derby® track is based on a different design you will have to check that it is compatible. The specific areas to check are that the spacing between the lanes does not exceed ten inches. Read more about the Space Derby® procedures and operational details.
Space Derby® Track Design from How-to Guide
Rockets are flown on guide lines of 50 lb. test monofilament fishing line. The suggested length is 40 feet, stretched as tight as possible. Sandbags or similar weight may be laid over lower bar for stability.
The addition of a strategically placed tab on the carrier at the back of the rocket helped to keep it from flying off the carrier backwards.
