Dayton Area HO Slot Car Club

Chassis
	Cars must run a T-Jet or Tuff-Ones chassis and gear plate. They must also run a pancake type motor.
	Any car may use brush barrel holders and any spring brush combination. The modified bullet chassis is most commonly used.
	Holes may be drilled in the bottom of the chassis around the motor to keep motor cool or for oiling. There may be no more than 2 holes drilled in the bottom.
	The rear corners of the chassis may be rounded off to accommodate sprint car bodies.
	The rear end of the chassis may be hollowed out so that the crown gear may be used on either side of the pinion gear.
	All cars must run the stock gear clamp. It must remain in its original stock position and may not be cut, sanded or drilled in any way.
	The body must be attached to the chassis using screws that pass through the stock screw holes of the chassis. These holes must remain in their stock positions.
	All cars must run at least the front screw for body attachment. All guide pins must be held in place by the screw only in its stock position.
Motor
	Cars may run rewound or quad armatures as well as AFX High Performance armatures.
	The two magnets surrounding the motor are the only magnets allowed in or on the car. The magnets must be in there stock position. At no time should they be lowered.
	Any magnet combination may be run.
	The motor may have the paint sanded off the outside if desired.
	No car is allowed to run bearings of any type on the motor nor on the axles.
	Cars using an Xlerator motor and gear plate may use Magna-Traction magnets and related gear assembly.
Pick-Up-Shoes
	Pick-up shoes must be completely stock.
	Cars must run stock or stock replacement type springs in their stock chassis position.
	Pick-up shoes may be adjusted for better contact to the track and to maintain clearance of the body but may not be flattened in any way.
Gears
	The gear plate must remain completely stock. The only part that may be cut is the top lip that runs along both sides. Also note that the front edge may also be thinned to accommodate lower bodies.
	Gears on the gear plate must still remain in the stock position. Plastic and brass gears are allowed.
	Any AFX crown gear may be run.
Suspension
	All cars must run two of the four axle positions already provided for by Aurora.
	Any AFX axles is allowed.
	All cars must run four wheels and four tires.
	Front and rear tires must be silicones readily available from the track owner. They may not be sanded but they may be shrunk. What we commonly use as rear tires must be used on front as well as back.
	Cars must run black tires.
	Spacers may be allowed anywhere on the axles.
	Four tires, one guide pin and two pick-up shoes are the only parts of the car that are allowed to and must touch the track.

Sprint Car Body All cars must use an Indy 500 Racer body or duplication. Cars may be built from duplication bodies that have been created from duplicate molds using similar material. 75% of the original body must be present. All cars must have the following:
	Roll Cage: Must be a complete four or six point cage and at least 5/16" above the top of the body. It must be made out of material that is tubular in shape and it must measure at least 1/32" in diameter.
	Cowling around driver: Must measure at least 3/16" above the body. Front must be at least 3/8" wide. Sides must be at least 1/4" wide. No gaps are allowed between cowling and the body. The only area of the body that is allowed to be open is the area inside the cockpit and cowling that is not readily visible. Note that tape is not an acceptable filler material.
	Cockpit: All cars must have a complete cockpit with original entire drive and steering wheel. The helmet does not have to be original T-Jet type. The area between the drive and the steering wheel must remain completely in tact.
	Weight: Extra pieces of plastic and metal may be added to the car for extra weight. However, all weight must be mounted on the sides of the body, within the chassis, under the nose or in the rear of the body. Large weights that extend beyond the nose or rear of the body will not be allow. No pans are allowed.
	Main Wing: Must be on top of the roll cage. The flat portion of the wing must measure at least 1" x 13/16". The wing is also required to have side boards measuring 2/8" x 1 1/8". The wing must be constructed from .016 gauge aluminum (available at most hobby stores). This includes the top surface and both side boards. Other materials may be used only fro reinforcement purposes. Side boards must extend above and below surface of the wing.
	Nose Wing: Must be positioned on the nose between the two front tires. It may not be mounted directly to the body. There must be some a support device used that raises the wing at least 1/16" above the surface area of the body. The wing must measure a minimum of 9/16" x 7/16" and have sides boards. The side boards may be made out of any material desired as long as it is solid in color. The flat area must be made out of .016 gauge aluminum.
	Nerf Bars: All cars must have a rear push bar and a front bumper. Side nerf bars are optional. Paper clips or similar brass material are most commonly used.
Height Requirements
	Body: Tail height should measure 3/4" from top of the tail to the track surface.
	Wing: Top rear edge height of the wing should measure a minimum of 1 1/8" from the track surface. The front edge should measure at least 1" from the track surface.
