I plan to have the track completed by Thurs June 23 so people can get some practice in. Cars can be ‘rough’ tested and tuned on our current straightaway.
Read the attached PDF. This is an experiment so we will figure some things out as we go along.
Our qualifying runs will be on Sat June 25. This will also be a day for extra practice before and after the qualifications. Qualifications will be 5 runs per car, per class. The average elapsed time (ET) will be your Index. This will be used during bracket racing to allow people with different times to be raced fairly.
Classes are essentially:
Super Stock (1/32): Orange Bell Motor, Hardshell body with driver, based on rules for Slot.It challenge (e.g. Group-C). You may want to use a ‘taller gear’ (i.e. smaller crown/spur or larger pinion) to increase your rear wheel RPMs well above 7500. The track is plastic so P6s and F22s are suggested. Zero-grips encouraged.
Pro Stock (1/32): Up to 30,000rpm any motor brand, Hardshell body, Lexan cockpit and driver, based on rules for Group-5, Can Am. Custom liveries encouraged, any chassis/body combo.
Comp Eliminator: 1/24 BRM and Parma RTR drag cars allowed. Up to 50,000rpm NSR long-can motor allowed (for BRMs and plastic shell 1/32). Parma motors limited to what was stock with the RTR drag car (Deathstar motor). Parma RTR cars need to replace the stock sponge tires with H&R Nascar wheels and rubber tires. Wheelie wheels must be adjusted to run on Carrera track.
1/32 Comp Elim– hardshell bodies, lexan cockpits, 40,000 NSR short can or NSR 50,000 long can allowed. Zero-grips encouraged. Credit-card wheelie bars may be required to prevent wheelies and keep braids in contact. Mark is making the wheelie bars.
Again – this is an experiment so expect a few changes….

The attached pictures include:
— A sample Parma 1/24 RTR car, with H&R rubber tires and NASCAR wheels installed. Spots where the wheelie bars may need some twisting with some needlenose pliers are pointed out.— Samples of credit-card Wheelie-Bars installed on two 1/32 cars with 39,000 rpm motors. To help keep the braids contacting the track, these cars have a 4gm tungestun plug glued just behind the front axles.
The wheelie-bars are 1×3 in strips from a credit card, gift card, or hotel room key. They are Sho-Gooed to the bottom of a 1/32 car, and the angle caused by the guide height will make the card angle downwards and press the track about 2 inches behind the car.
You MUST USE A CARERRA STRAIGHT as your setup block for tuning the wheelie bar. Naturally I will help you.
Tuning consists of carefully trimming the length of the card, until the rear tires are making full contact, -and- the edge of the card is touching the track. The card provides a light spring action that keeps the guide buried in the slot and the braids touching the rails. You can fine-tune the spring strenght with guide spacers. Also – you will need to add holes for any body screws that the bar may cover.
Wheelie bars are NOT needed with the Super-Stock cars; just with Pro-Stock and Comp Elim cars with very strong motors.
