   2. The model must have a minimum consistent scale of one and onehalf (1 1/2) inches to the foot (1/8 scale). All scales must be within a plus or minus 5% for the top and side profile views, with the exception of the stabilizer area and the fuselage width. (This allows for profile type models). Models which appear to comply with this tolerance upon rudimentary inspection need not be further checked except in case of dispute.
      1. Stab area may be increased up to 25% of the wing area, but must maintain scale configuration.
      2. The landing gear must be of the same configuration as the actual aircraft, e.g. two separated struts, and must exit from the scale location but may be longer, higher, or swept forward. (wheel pants are optional).
      3. Cowls or "apple cheeks" as used on the full-size aircraft are recommended but not required.
   3. The model must have a scale-like paint scheme not necessarily the same color, but representative of full-scale racers.
      1. The scale canopy outline may be clear or painted a contrasting color.
      2. Model must have racing numbers on the fuselage and on the upper left wing.
      3. The contestant's AMA number should appear as part of the scale-like license number on the upper right wing. It may be preceded by "N" at the contestant's option.

5. Field Layout.
