SUPER STOCK

1) This Class uses a Saturn 20t motor and suitable speed controller or a Track Star 80A water proof ESC and a 540 2pole 4000kv (this is sold as a combo unit). The speed controller is turned down by 40% to make it equal to the Saturn 20t brushed motor. To do this please see Gary Sims, Michael Smith or Stewart Smith who have the program box required to make the changes.
2) The gear box must be of original ratio and a maximum 20t pinion used 21t for M02,4,6.

Other Motors, ESC’s, Pinions and Gear box’s may be used by arrangement with other M-class races for the purpose of testing for no longer than one month (Four Meetings). After which a decision will be made as to weather the modification will be excepted or not.

MODIFIED RULES

1) Any class other than Tamiya 2wd M-class chasse comes into this class.

These rules are for club racing only and are meant to make racing fair and even, other clubs may use other rules. These rules will be changed from time to time as the track evolves and new testing completed and agreed by a majority of on road out door M-class Racers.
Testing new drive train parts (ESC, Motor, Gears, ect) must be communicated to other racers before racing on the day and the car may be excluded from any race series going on at that time. Normal race conduct applies.
