HAND LAUNCHED GLIDER AND CATAPULT GLIDER

1. Applicability. All pertinent AMA regulations shall be applicable, except as specified below.

2. General. An Indoor glider is a non-powered model aircraft designed to fly indoors.

3. Classes. The following classes shall be recognized for competition and National Records:

a. Hand-Launched Glider.

b. Standard Class Catapult Glider.

c. Unlimited Class Catapult Glider.

4. Size of Supporting Surfaces. The projected area of a supporting or stabilizing surface is the area seen when looking directly down on the surface. Supporting surface area enclosed in a fuselage or stick shall not be considered as wing area. Projected area of horizontal stabilizing surface(s) in excess of 50 percent of the projected area of the supporting surface (wing area) shall be considered as wing area.

a. Hand-Launched Glider. The projected area of the supporting surface(s) must not be more than 100 square inches.

b. Standard Class Catapult Glider. The projected wing span must not exceed 12 inches. The projected wing chord shall not exceed three (3) inches. The area of the horizontal stabilizing surface(s) shall not exceed 50 percent of the projected wing area. Standard class is limited to monoplanes.

c. Unlimited Class Catapult Glider. The projected area of the supporting surface(s) must not be more than 100 square inches.

5. Construction. All surfaces shall remain fixed except for changes of camber or incidence due to natural flexing of the surfaces. Folding wings and mechanically actuated incidence changes are strictly prohibited.

6. Launching. Launching shall be appropriate to the class of model. In all cases, the launch shall be made with force sufficient to cause the glider to immediately gain altitude equal to three (3) times the flier's height or half the available ceiling height, whichever is less. The model shall not be launched from a height greater than the flier's normal reach above the floor.

a. Hand-Launching. The model shall be released into flight directly from the hands of the contestant, without other assistance.

b. Catapult Launching. The model is launched by stretching elastic band(s) between the hands of the contestant, with one end(s) firmly attached to a launching handle. The handle shall consist of a rigid dowel or similar device, with the elastic band(s) firmly attached.

The launching handle (including the attachments for the elastic) shall not exceed six (6) inches in length, measured along the longest dimension. The handle may use padding or contoured grips for flier comfort. There is no limit to the length or sizes of the elastic bands. All launching apparatus must remain firmly attached to either the handle or the model during launch. There is no limit to the number of launching handles a contestant may use to complete his/her flights.

7. Number of Gliders. Each contestant shall be permitted a maximum of three (3) gliders per contest. The three (3) gliders used may be of different design.

8. Official Flight. All flights are official flights, regardless of duration. Unofficial flights are not recognized. A flight during which any part is dropped shall be declared an official flight with zero (0) time.

9. Number of Flights. Each contestant shall be allowed a total of nine (9) official flights.

10. Scoring of Flights. Scoring time shall be the total elapsed time of the best two (2) of not more than nine (9) official flights. Flight duration shall be scored in tenths of seconds, with hundredths of a second dropped. Example: 65.17 seconds shall be recorded as 65.1 seconds.

11. Flying for Record. The same ceiling height categories and specifications apply as for Indoor Rubber models.
