OCC GT-1 (including Junior, and Open A and B Divisions)

1.0 Purpose: OCC GT-1 is a Class designed to equalize all aspects of the race, except the racer. It is also designed to provide low-cost, competitive racing, and allow racing using the basic equipment normally found in a "starter kit".

2.0 General Rules apply.

3.0 Controllers: Must run a standard resistor controller with NO adjustments such as "punch", sensitivity, or brake. No electronic or external-resister controllers are permitted in the Class.
  • 3.1 Permitted controller modifications: You may change gauge (but not number) of controller wires, and/or attach a heat sink.
  • 3.2 You may not add a "full punch" or "clicker" relay.

4.0 Chassis: see General Technical Rules.

5.0 Gearing: Must run 48 pitch / 28 tooth plastic spur gear, on 1/8" rear axle, NO hollow axles. (Pinion gears will be provided on the handout motors.) Motor pinions are set for running the spur gear "hub out".

6.0 Body Rules
  • 6.1 May run any body from approved list.
  • 6.2 Driver figures: see General Technical Rules.
  • 6.3 Must use an interior and detailed driver (similar to Parma 808); windows must be left clear.
  • 6.4 Decoration: See General Technical Rules.
  • 6.5 Must retain a min. 1mm. (.039") "vertical" front bumper.
  • 6.6 Rear must retain 1/2" "bumper" below wing.
  • 6.7 Max. rear wing height 1-5/8".
  • 6.8 Approved TRRS GT-1 Bodies- Updated as new bodies are released suitable for Class.
    • Parma/Champion:
      • Mercedes GT-1 1044
      • Mercedes 1019 Porsche GT-1 1045
      • Mosler MT-900 (Champion)
    • JK Products:
      • Saleen GTS 7112
      • Audi R8C 7182
      • Bentley 7197 & 7207
      • Mercedes CLR 7183
      • Toyota GT-1 7176
      • Porsche 7178
    • Outisite:
      • Mercedes OS-088
      • Porsche OS-082
More bodies to be added as soon as approved.

7.0 Motors- OCC GT-1 uses hand out sealed Parma 501 16D motors with 8 Tooth 48- pitch pinions.

8.0 Race Day Procedure GT-1 Divisions
  • 8.1 Motors are to be handed out with the objective of allowing racers minimum access to the motors before the race.
  • 8.2 Motors are selected by the racer from a box, which allows full view of the motors. Racers cannot pick up the motors and examine them- once a motor is touched, that is the motor the racer selected.
  • 8.3 Method 1- motors are selected, and soldered into the car , by the racer, at the tech table. OCC will supply soldering iron(s) at the table for this purpose.
  • 8.4 Method 2- (this method is not preferred, since it allows more access to the handout motors by racers.) Motors are selected, and taken to the racers pit. A maximum of 15 minutes is allowed for the racers to solder the handout motor into their chassis. In this case, the car is teched AFTER the motor is installed.
  • 8.5 In all cases, cars are impounded, and "gridded" (by heat) just as the 2-minute practice is started.
  • 8.6 "Luck of the Draw": Handout motors are broken-in and maintained by OCC. Every effort is made to have "equal" motors, but there will be minor variations in motors. There are no exchanges for motors that may be slower than others. Any variations are "luck of the draw" and the racer will have to race with that motor.
  • 8.7 (Using handout motors) If a car fails to run (will not start) when the power is "on" for the race warmup, racer and OCC Race Director determine if the motor is defective, or if it is something in the car causing the problem. If defective, another handout motor will be issued. Racer has to repair any problem with car or installation during the warmup.
  • 8.8 Motor failure during a race is not anticipated due to the spec gearing and maintenance of the motors. Motor failures during the race are presumed to be caused by the car being defective (bound axle, etc.), and the racer has to withdraw- there are no substitute motors.
  • 8.9 NO changes (including replacing brushes, "tweaking" springs, brush hood alignment, changing pinions, or timing) may be made to any handout motor. Racers are asked not to use ANY fluids except oil or lighter fluid, on the handout motors- fluids such as com drops or Voodoo Drops are STRICTLY PROHIBITED! Lighter fluid may at anytime be checked by Race Director for foreign substances and his determination is FINAL.
  • 8.10 Any racer found to be modifying an OCC Handout Motor, or substituting another, will be disqualified, and will score zero points for that GT-1 race, with no refund of entry fees, or dues. A second offense will result in the racer being asked to leave the Series.
  • 8.11 Race Director can run GT-1 Division B drivers in Division A, or vice versa, (but score in their regular division) in order to even out the heats and/or reduce the number of required races.
