1978-79 COMPETITION RULES ANNOUNCED

With the conclusion of the Final Vote by the Free Flight, Control Line, Radio Control, Scale and Combined Contest Boards as reported in chart form in this issue, most of the work has been done in the two-year process of updating (adding to or revising) the AMA competition rules for 1978-79. Remaining is the resolving of any anomalies or contradictions which may have resulted from the voting, plus any editing which may be required for consistency or clarity (but with no change of intent). Much of this work will be done by each Board's chairman. They, together with all the Board members, in our opinion, are to be commended for many hours spent, and dedication, in representing their districts—frequently in the face of wide diversity of opinions and wishes on a given subject.

Plan your '78 competition activity now. While this report can't completely take the place of the 1978-79 rule book, the significant aspects of the new rules are shown in the description column of the voting charts. Each of the items shown with an "A" (for acceptable) in the results column, represent a change from the 1976-77 rules to be applicable in 1978-79; those with an "N" were defeated and won't be in the new rule book.

Free Flight Final Vote. By mistake, proposal 39 (to limit models in the Pennyplane event to monoplanes) was omitted; another Final Vote ballot is being circulated to the board to cover this point. And to avoid other possible misunderstandings, proposal 38 (to limit the Novice Pennyplane event to monoplanes) is being re-voted as is 38/39B which, if accepted, would limit both the Novice Pennyplane event and the Pennyplane event to monoplanes, and add the provision that a flier may enter either the Pennyplane event or the Novice Pennyplane event at a given contest, but not both. Related to 38/39B, additional questions are being asked to determine whether a "contest" is interpreted to include Record Trials.

Radio Control Final Vote. As shown by double asterisks in the chart, inconclusive results were obtained on several of the proposals. The Board is being asked to vote again on these proposals in a fashion which, we hope, will produce positive results.

Notes: Proposals passing the Final Vote by a margin of two-thirds among those voting (to the nearest whole number) become new AMA competition rules effective January 1, 1978. Where there are three alternatives to a basic concept, they are ranked in order of desirability, and the one with the least total passes if the basic concept is accepted by a two-thirds majority. A blank box means no vote was cast. and land. Five minutes flight time.

  1. Scale contestants will fly same equipment as static judged. Should part of aircraft be damaged so as to be replaced, that portion of aircraft will be re-judged.
  1. Scale contestants will present the following materials with helicopter for static judging:

a. Published three-view drawings. b. Pictures, published or otherwise, pertaining to color, markings, and details. The better the presentation, the better it can be judged.

  1. Scale entries will be judged on the following (maximum of 25 points each):

a. Fuselage b. Cockpit c. Landing gear d. Rotor systems e. Craftsmanship f. Finish and markings

  1. Scale winning points will be the sum of the best two flights plus static judging points.
  1. All maneuvers will be judged 0-10 and have an additional K-factor multiplier as indicated.
  1. All models will have contestant's AMA number affixed at contestant's discretion.
  1. Protests: Protests will be in writing and hand delivered to event director or CD immediately after flight in contention. The protests will state specific infraction—by whom made, when made, and signed and dated by protestor. All protests will be settled using these rules.
  1. Helipad: Helipads will be three feet in diameter. One helipad will be located fifteen feet ahead of the main pad into the wind, and the third pad will be located fifteen feet to the right of the main pad—90 degrees to the wind.

FREE FLIGHT PROPOSAL DESCRIPTIONS

29A—Ornithopter Definition (Meuser). Substitute the following for 5.6: An ornithopter model derives its propulsion solely from the flapping of its wing(s) or parts thereof. If part of a wing is fixed, the projected area of the flapping part shall be not less than that of the fixed part, and the fixed part(s) must not extend ahead of the leading edge or behind the trailing edge of the flapping parts. If the model has more than one wing, these restrictions apply independently to each wing, and the wings shall be substantially identical in size, shape, relative areas of fixed and flapping parts, and excursion of the flapping parts. The projected area of a flapping part is to be determined at a position midway between its extreme positions. Horizontal stabilizing surfaces must be at the extreme front or rear of the model, and the total projected area of such surfaces shall not exceed 50% of the total.
