We are pretty basic when it comes to rules, we are more about having fun on race nights... that being said there are a few rules that we must put in place to keep everyone safe and protect our club venue....

Electricity will be provided however You will need to furnish your own pit tables, chairs & extension cords!

Close toe shoes must be worn. (THAT MEANS NO FLIPPITY FLOPS OR SANDALS!!)

No cars can be added to a race once it starts, If your car is not on the starting line when the race begins forget it... you will just have to wait for the next race to compete.

If you pull your car from a race your done, if you break or if you dump no fixing it or changing batteries and launching back out mid race!!

Remember guys and gals this is done for fun and we are all about seeing the hobby grow. We all will be faster and have more fun with the car count climbing and new racers joining in.

No reverse, if possible locked out on your ESC (Penalties will be enforced for breaking this rule)

All vehicles must be free of dirt, mud, oil and etc… our carpet is expensive and needs to last

Racers must provide their own Robotronics style transponders, the club has some available for rent or purchase

It takes 4 to make a class, we may combine classes to fit you in – no racer will ever be turned away from running

10.5T Motor Rule – unless the class specifies otherwise no car shall ever run lower than a 10.5T Brushless motor

All Lipo batteries are to be hard cased. Batteries must NOT be charged beyond their design voltage (4.20V per cell for standard LiPo’s). - No Lipo or battery warmers are allowed.

LiPo batteries must be charged in flame retardant charging sacks designed for LiPo batteries.

MRCRC is meant to be a family friendly atmosphere for all ages. Please be respectful. No unsportsman-like conduct or foul language will be tolerated!

SXT Odorless traction compounds (sauce) only!



We use Robotronic compatible transponders:


There are NO house transponders however we do have a limited number of rentals for $5.00 per race day and practice event. (Drivers License or Security Deposit will be required for rentals!)
