Schneider Cup Re-Enactment Rules


Eligibility: Any aircraft that was designed for entrants into the Schneider Trophy Races, whether or not it actually competed, is eligible. See Appendix “A”

Size: Any aircraft regardless of scale, bi-plane or monoplane must have a minimum of 85 inches.

Weight: No aircraft can exceed 55 pounds including fuel and ready for take off.

Engine Size: Unrestricted

Scores: The overall score will result from the total of three figures.
1)50% from static
2)25% from Flight
3)25% from Speed Trials

Scale: Each entrant shall declare the scale of his/her model at the time of entry. Scale is defined as the linear dimensions of the model divided by the linear dimensions of the prototype, to three decimal places. For example, if the prototype had a 36-foot wingspan and the model has a 12-foot span, the scale is 0.333. Providing the proof of scale is the responsibility of the contestant.

Documentation: Presentations are limited to no more than 8 pages (one side) sized 8.5″ X 11″ or an equivalent area of some other arrangement. Three view drawings larger than 8.5″ X 11″ or more than one page are permitted and will count as 1 page of the 8 allowed. Three views larger than 8.5″ X 11″ must be submitted flat and mounted on a stiff backing.

Static Judging: (max 100 points) Judging will adhere to the AMA Standoff Scale Rules. Judging will be from 15 feet distance. Up to 8 pages of documentation is allowed. Color documentation, either description or photo must have been published in an accredited source. Outline in profile, front and plan form must be supplied. If a pilot was visible when the prototype flew, the model must have a man like figure also in the cockpit. Cockpit detail such as instruments etc. will not be judged. Water rudders and step location changes will not be judged in the interest of safety.

Accuracy of Outline: (max 40 points) To be eligible for Accuracy of Outline points, one of the following must be provided by the contestant.
a. 3 view drawing showing the side view, front view and plan view.
b. A selection of photos of the aircraft modeled, sufficient to show the outlines in side view, front view and plan view that will allow the judges to interpret the outline accuracy.

Finish, Color and Markings: (max 30 points) To be eligible for Finish, Color and Marking Points, the following must be provided by the contestant: a. A color description or photo published from any origin.

Craftsmanship: (max 30 points) All models entered will be eligible for Craftsmanship points. In the event, a model does not qualify for one or both of the Accuracy of Outline, or Color and Markings categories, points will still be awarded for Craftsmanship.

Scale Pilot: If the pilot is visible in flight in the prototype aircraft, then a man-shaped pilot of Scale size must be visible in the model in flight.

Mufflers: Static points will not be deducted for non-scale mufflers provided an effort was made to conceal them.

Water Rudders: In the interest of water handling and safety, water rudders are recommended and points for fidelity to scale will not be deducted for this.

Floats: On some aircraft, the step location causes the aircraft to perform poorly. In the interest of safety, step locations can be moved without a point’s penalty.

Time Trials: (max 50 points) For this event, speed is related to visual speed. By this, we mean that if the prototype flew by at 200 mph one mile away, a ΒΌ scale model would fly by close in at 50 mph. This would visually appear the same. Therefore you will take the speed of your aircraft in the full-scale event, divide by the scale to three places and that will indicate your target speed. If you replicate an aircraft that did not compete in or complete the course, then a speed of 80% of the winning speed for that year will be used. For early aircraft where their target is less than 30 miles per hour, then 30mph will be their target speed. All contestants begin with 50 points, and the percentage of their target speed vs the actual speed flown plus or minus will be deducted from the 50 points. For example, A speed of plus or minus 18% of the target speed will receive 50-18=32 points.

Flight Realism: (max 50 points) This is the most subjective part of the event. Both contestants and judges have to cooperate in the judging. By this, we mean that if an aircraft had unusual taxi, take-off or flight characteristics that can be documented, it is the responsibility of the contestant to inform the judges prior to the flight. Points cannot be changed after the scores are recorded.

Judging: Models will be judged on flight realism based on the appearance of the model during water taxi, flight, and landing. Each round will be judged by two or more judges. Each judge will, during each heat, observe and score each of the aircraft for a realistic taxi, take off (reaching 10 feet of altitude constitutes a take off), flight pattern, landing and return taxi. The judge’s scores will be averaged for each aircraft to determine the score for that heat. There will be 10 laps for each heat. If all four heats are flown, the lowest average score may be thrown out and the average of the top three will determine the contestants Flight Realism score for the day. The average of the contestant’s daily scores will determine his overall score.

Taxi and Takeoff: (max 10 points) Realistic taxi and takeoff.
Course: (max 10 points) Adherence to the course
Altitude: (max 10 points) Maintaining a steady altitude between 10 and 80 feet.
Speed: (max 10 points) Maintaining a realistic flight speed throughout the course.
Landing and Return Taxi (max 10 points) Making a realistic landing and return taxi.
