Race Rules for All Classes

All LiPo batteries must have a hard case.
Batteries must NOT be charged beyond their design voltage (4.20V per cell for standard LiPo’s).
No reverse allowed during races. It must be locked out in your speed control.
No traction control/ABS/AVC/gyro or other electronic driving aids allowed.
All vehicles must meet their class’s minimum ride height requirements. No part of the vehicle can drag on the carpet. 3mm minimum for 1/12 scale pan cars and 5mm minimum for most other classes. See class rules for specific requirements.
All vehicles must be free of dirt, mud, oil, etc. Our carpet racing surface is a significant investment.
Although we have a limited number of handout transponders, we recommend that racers provide their own. Handouts are first come, first serve and need to be returned to the charging rack after each race. We use MyLaps RC4 transponders (AMB/2-wire/3-wire/MRT mPTX)
If we do not have at least three vehicles in a class, we may (at race director’s discretion) combine classes.

The diff will be considered locked if opposing wheels turn in the same direction, therefore considered not legal to race on track. Locking the diff with putty, ear plugs or HIGH viscosity grease is not permitted.
