Raceday Schedule & Fees

Entry fee is $15 for your first class and then $5 for each additional class.

The standard racing format will feature practice, 2 rounds of qualifying heats, then the mains.  Each events Raceday Sschedule will be posted on our Facebook page.

Transponder Requirements

You are REQUIRED to race a Trackmate Transponder.  You can purchase them at the track for $40 or purchase online at www.trackmateracing.com. 

 

We will be using the Trackmate Scoring System which is an Infrared system that REQUIRES LINE OF SIGHT between the transponder and the overhead scoring loop. So you MUST MOUNT TRANSPONDER WITH CLEAR OVERHEAD LINE OF SIGHT.
This will be pretty easily done in the 1RC Cars that have open cockpit areas or clear windshields. For the Losi NASCAR division, you will probably need to cut a small hole in the body to bring the transponder in clear sight. You can Google this and get some ideas, there’s a lot out there on that. This is a pretty minor modification so shouldn’t give anyone any issues.
Also for the Losi NASCAR cars, you will need to purchase this Y-Splitter below to be able to connect the transponder to the car. This Y-Splitter will go in the fan plugin and then you can plugin the fan plus the transponder. Here is the link: https://www.amazon.com/gp/aw/d/B07PHDYZXN
