Section XIX-B.
The following requirements must be met for your vehicle to be allowed in competition. All vehicles are subject to inspection at any time before, during, or after the event for legality. This section covers the electronics (speed controls, servos, batteries) allowed in competition, and also covers transmitter specifications.
1. Any 2 or more channel radio system specifically designed and marketed for RC surface use may be used. Frequencies must be clearly marked for identification.
2. Please bring a spare set of crystals if you’re running 75 or 27mHz crystal-based systems in the event that there is a frequency conflict.
3. Spread spectrum-type radio systems (i.e. Spektrum DSM, Airtronics FHSS, Futaba FASST, etc.) are allowed and encouraged.
a. Some venues may require the use of spread spectrum-type radios only for safety reasons (for example, at a full-sized motorsports venue where radio comminucation cannot have interference by standard AM or FM RC transmitters)
4. Any electronic speed controller (ESC) designed and marketed for RC use may be used.
5. Reversible and/or brushless ESCs are allowed.
a. Please exercise caution before you use the reverse function on the track, especially when there are others on the track with you.
b. Use of reverse during qualifying or tandem battle may be considered a driver error.
6. All ESCs must be correctly wired, with no potentially dangerous situations such as frayed wires, broken FETs, etc.
7. Mechanical resistor-type speed control units are not allowed.
8. Any Ni-CD/Ni-MH sub-C sized battery pack specifically designed and marketed for RC use may be used, with a voltage rating no more than 7.2v, a capacity no larger than 6000mAh, and no more than 6-cells.
9. Any LiPo battery pack specifically designed and marketed for RC use may be used, up to 7.4v and 2-cells (“2S”) is allowed, provided it fits the stock battery location. Please exercise proper safety procedures if using Li-Po packs.
10. Any standard-sized steering servo designed to fit a 1/10-scale touring car chassis is allowed. This includes “low-profile” servos, FET servos, and brushless servos.
11. Some events or competitions may have modifications, exceptions, or additions to the rules above.
