Early Modified Rules
Bodies
- 1/24 or 1/25 scale American iron from 1928 to 1948 coupes or sedans, no convertibles. (Models with chopped tops OK). No fenders
- Bodies can be cut across the bottom so as to have a minimum body height of 1.930" at the lowest point of the top as measured from the bottom of the chassis to the “top”. The top is measured from the point about 3/8 from the window moving back along the roof (where the roof flattens from the curvature connecting the windshield from the roof – this may vary from car to car)
- Bodies may not “float” on the chassis.
- Sunroof may be cut out. Maximum dimensions are 1.75 wide inches by 2 inches long. The sunroof must be located above the drivers’ seat
- Running boards may be installed to cover the bulk of the Econo chassis side pans. As an alternative, the side pans may be painted or covered with tape. (I have found that Gorilla tape works quite well. It is OK if the rattle mechanism and/or front or rear push bar attachments are visible).
- Front window screen must be attached (no windows are to be installed).
- Full drivers tray with a painted driver must be installed
- Must have a scale motor and radiator up front (oil pan can be modified to fit on top of the chassis).
- Top hoods are permitted. If a top hood is installed, no firewall is required. Firewall is required if the vehicle does not have a top hood
- Piano wire side bumpers are permitted, not to extend beyond the tracking of the tires.
- Rear bumpers/push bars may be installed but should not extend over an inch beyond the body work.
- Front bumpers/push bars may be installed to protect the guide flag but should not extend more than an inch from the front edge of the guide flag.
- Numbers are required on each side of the vehicle and must be at least .5 inches tall.
Chassis
- Only stock Econo rattle chassis are allowed with no modifications (for example; side pans may not be cut down).
- Stock front and rear tires are required (no tapering of front tires allowed. You may use ProTrack front and/or rear tires, however they must be of the same diameter specified for the OSCAR Econo Class).
- Only 48 pitch gears are permitted and 1/8 axles are permitted.
- Chassis may use bushings (no bearings allowed)
- No independent movement of the front axle from the chassis is permitted
- Tires may independently roll.
- Front and rear track not to exceed 3.250"
- Minimum ground clearance will be .055 inches
Motors – Any D can motor allowed in OSCAR rulebook is allowed (no Hawks, Falcons or small can motors are permitted)
