  • Modified Class

M-Chassis Stock

1) This refers to the motor that must be a 540 Mubuchi silver cam motor and a maximum 20 tooth pinion (21t for M02,4,6).
2) Gear differential may be fitted but other gears must be as per kit Ratio. (Hard gear box allowed as it the same ratio)
3) Other hop-ups are allowed as long as they don’t give a speed advantage.
4) The body shell is open so any M-class body shell can be used.
5) Tyres are open as long as there made for M-class and no larger than 60D .
6) Batteries are restricted to LiFi or Lipo hard case 2 cell (8.4v) or 6 cell (7.2v) Nims or Nicad.

M-Chassis 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.
3) Other hop-ups are allowed as long as they don’t give a speed advantage.
4) The body shell is open to any M-class body shell.

6) Batteries are restricted to LiFi or Lipo hard case 2 cell (8.4v) or 6 cell (7.2v) Nims or Nicad.
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.

Tub Chassis Touring Car

There has been some recent discussion about how to run a touring car class at the outdoor track but on a budget. After much discussion we have now decided on the following as a starting point which may be developed in the future

Car
Any 1/10th shaft driven tub chassis touring car with a nominal width of less than 200mm, such as the Tamiya TT02 or similar.

Power
Any hard case 2s LiPo or 6 cell Nicad or Nimh battery. Motor and speedo, Turnigy 4000kva waterproof system as used in the M Chassis class or any brushed motor.

Bodyshell
Any 1/10th scale replica type body such as GT cars, Muscle Cars, Rally, DTM, Truck etc but no BRCA approved touring car bodies.

Tyres
Any 1/10th treaded touring car type tyres. Tyres must not protrude beyond the bodyshell.

As mentioned, these rules are a starting point to see how the class progresses and may be altered as required in future.

Modified

1) Any class other than Tamiya 2wd M-class chasse comes into this class.
2) Any Motor, ESC can be used as long as it safe to use (suited to the track and conditions).
3) Body shell is open to any shell as long as it covers the moving parts (wheels and gears).
4) Gearing is open and unrestricted
5) Hop-up unrestricted as long as there safe.
6) Tyres are open up to a limit of 62d.
7) All LiFi and Lipo batteries must be hard cased.

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.
