A Page Devoted to the Technical Aspect of our Rules Enforcement and the Tools Used.

No Rocket Science Allowed!

To those who have not raced with HO Racing Association of St. Louis, or those who are new to our group might not completely embrace our practices mainly because they don't understand what the primary cornerstone of the group is: Use the original Aurora T-jet chassis in an unmodified basis. Once you understand that, then the tools we use will start to make sense. They are uniform in that they apply to everyone and if some feel they are unduly restrictive or lacking creativity, they do so for everyone. Our playing field is what we believe the levelest one found in the country. Those with "deep pockets" are not favored over anyone else. These tools and the rules they support work very well for us and have served us for many years now. There are newer chassis or platforms available, and we make no judgements on them what so ever, we perfer to utlize only the original Aurora platform, nothing more.

The mysterious "Black Box" our dreaded and feared Sith Tech Inspector brings each week to the races.

The "Black Box" is opened!!! GASP!!!.

The backbone tool of our tech inspection: the complete Dyno is a model of simplicity. Made up of a 13.8 V wall wart power supply, some wire, a cheap digital multi-meter and the dyno platform made from a small section of track.

The dyno platfrom exposed underneath. A Tyco HP7 motor used as the generator is connected via brass tubing to another axle with two HP7 or 440X2 wheels and tires that the cars sit on and spin when power is applied (from the wall wart). The multimeter leads attach to the HP7 motor. Our rules allow for standard tire size classes to generate no more than 1.0 volt, large hub/tired cars like Indy Roadsters or Pro-Tjet cars no more than 1.25 volts as read on the multimeter when run for no more than 4 seconds.
