T-Jet Spec Class

BURN Thunderjet 500 spec class

BURN T-jet racing uses readily available chassis and bodies with stock parts.  The goal is to create a closely competitive class of cars that are inexpensive to build and race.

The rules are as follows:


Any chassis that is based on the Aurora Thunderjet chassis including all versions produced by Autoworld (AW), Johnny Lightning (JL), Playing Mantis, Model Motoring, MEV, Road Race Replicas and the Dash Motorsports T-Dash.  If you are unsure, please ask.

All Autoworld Ultra G chassis must have the traction magnet removed. 

Removal of material on the top plate to enable body fitment is permitted.

Motors, electrical components, axles and gears

Only standard parts from the chassis stated above may be used. However, Autoworld or Dash parts may be used as replacements in other chassis, since these are currently manufactured and are more readily available.

Wheel & axle width

Cars must be raced on standard axles with a standard overall width front and rear.  We are aiming for a good-looking T-jet car, so front wheels should fit inside the body. Rear wheels can protrude only if a Tuff Ones chassis is used (eg Johnny Lightning or Autoworld Thunderjet 500), with a maximum rear width of 1 3/16” (1.188 inch) = 30.175mm. If aftermarket replacement wheels are used, they must fit within the body. Fray-style set ups may not be used.

Tyres & wheel weights

Any single compound tyres are permitted. Silicone-coated sponge tyres are not permitted.

Brass washers (M3.5 recommended for AW wheels) are permitted on the inside of the front wheels to act as wheel weights. JW Speedparts F-16 front wheel weights are permitted for JL front wheels.


Bodies must be made of ABS plastic, 3-D printed material or resin. No lexan bodies please.  

Bodies should be a saloon or convertible car, preferably of a type used for racing, although racing numbers are not required if you prefer the street look.  We like the American muscle cars from the 1950s, 60s and early 70s.

The following styles of bodies are respectfully not permitted: Sand Van, Speed Racer, Ice Cream Truck, Batmobile or Willys Panel Van.

There will be an award for the best turned-out T-jet (body, stance, livery & wheels) at each event.
