Many new scale modelers ask how to modify the outline of an airplane for a profile body.

Model Requirements: Add the following new paragraph.</p><p>2. Design and static Judging Guidelines: To maintain the scale wing and tail span, the leading and trailing edges of the wing should be extended to the center line of the body, without changing the overall wing span of the model. Since the flaps and ailerons are part of the wing they should remain scale size and shape. If the airplane had a wing fillet, the fillet should remain scale size and shape and be located at the profile body. In a like manner, if the plane modeled (like a P-51 for example) has a leading edge extension or other similar feature, the feature will be of a scale size and be located at the profile body. The Horizontal Stabilizer and or Elevator should be done in a similar manner as the wing. Reducing the model's overall wing and tail span the same amount the fuselage was reduced to create the profile, is cause for loss of static points. Logic behind proposed change, including alleged shortcomings of the present rules. State intent for future reference. </p><p>Many new scale modelers ask how to modify the outline of an airplane for a profile body.
