On race tracks with high GForce you may experience the rear crown gear grind on the motor shaft. It seems this may be related to the NSR crown design where weaker plastic teeth and any slop is the gear/shaft alignment leans to excessive wear. Be careful to eliminate sideways slop from gears and ensure motor is tightly fitted to chassis
You can use either of two alternate crown gears to replace the OEM NSR crown. All three have black plastic teeth, so it is easy to monitor. You can replace with:
NSR 6327BR Inline 27 tooth crown brass hub

Ballast / Weight: not allowed in this class
Magnet: must be removed and placed on nearest fridge or donated to the Large Hadron Collider
Lights: you are free to add brake lights or exhaust “flash” lights (Note: I might give you an extra half lap per heat if you add them – just don’t tell anyone else)
Eligible Cars: From NSR there is one body style but 25+ liveries from which to choose and white kits to allow you to create your own livery. In spirit, this is essentially a stock class “Drivers” championship
Also eligible are hybrids, defined as any plastic or resin bodied period rear engined Formula 1 car running on the class eligible OEM NSR chassis/ drive-train/ wheel/ tire combination.
The cars MUST specifically be approved in advance by Stephen (no exceptions and no other person can allow or disallow a hybrid car once it is approved);
The chassis must sit flush with the body of the car, as it is with all other class eligible cars;
The body must, at minimum, weigh the same as the average of the OEM class eligible cars. For this class that weight is 11 grams and any makeup weight must be added to the inside of the body, not the chassis to avoid any COG advantage occurring.
No need for pre-approval if using an NSR white kit
Pictures of the eligible car body style in the class is below. Below that is a table of (almost) all cars released in this class with a live link to an image of the car.
