  • Submit reports to the MACA newsletter and website regarding standings at least quarterly; and
  • Submit the year's totals for publication no later than January 31 of the following year.

Section 2: Method of Rating: The rating system is calculated on points:

  • Placement Points: Points are awarded for placing in sanctioned contests, and the sanction must specify the events (as to type and number of events) that will be flown at that contest. Winner's points will be calculated by multiplying the number of entries ($N$) in an event times the place:
    • 1st Place: $5 imes N$ points
    • 2nd Place: $4 imes N$ points
    • 3rd Place: $3 imes N$ points
    • 4th Place: $2 imes N$ points
    • 5th Place: $1 imes N$ points
    Example: In an event with 10 contestants, points awarded are 50 for first place, 40 for second, 30 for third, 20 for fourth, and 10 for fifth.
  • Participation Points: Points are also awarded for each participating contestant in an eligible event. One point times the number of participating contestants ($1.0 imes N$) is awarded to each entrant who flies at least one match in the event. To qualify as a participating contestant, the pilot must enter the contest and fly at least one match. For the AMA National Championships, 1.5 points times the number of contestants ($1.5 imes N$) is awarded to each entrant who flies at least one match in the event.
    Example: In a normal sanctioned event with 30 contestants, participation points awarded would be 30 for each participating contestant. At the NATS, entry points for a 30-entry event would be 45 points.

Section 3: Prior Membership Requirement: In order for a contestant to be included in the Top 20, they must be a member of MACA before the contest where the Top 20 points were earned. Non-members receive zero rating points.

The rating system provides for annual rankings in:

  • Top 20 Overall
  • Top 10 Fast
  • Top 10 F2D
  • Top 10 1/2A
  • Top 10 Speed Limited Combat

* Note: Non-rulebook events will be tabulated where most appropriate.

Section 4: Contest Season & Eligible Sanctions: Placing in unrestricted AMA, Canadian (MAAC), or WAM sanctioned contests will be considered for rating purposes. The contest season shall run strictly from January 1 to December 31.

Section 5: Seven-Day Reporting Deadline: Only those reports available to the MACA Vice President for the Top 20 shall be considered for rating purposes. The reports must include: Contest Name, Location, Sanction Number, Date, Event Number or Event Name, Number of Entries for each event, Names of 1st, 2nd, 3rd, 4th, and 5th place finishers, Names of all who entered and flew at least one match, and the CD's Name along with the CD's AMA Number. The report should be sent to the Vice President for the Top 20 within seven (7) days after the contest.

Section 6: Recognition: The Board shall provide suitable recognition for those on the final standings lists.

Section 1: Skill Class Designations. The MACA skill classes are Sportsman, Advanced, and Expert. The distinction between classes is based on the contestant's current proficiency level as a Control Line Combat pilot.

  • Sportsman is the beginning class. Competitors in the Sportsman class may be proficient in other events and may have entered Combat events, but should not be accomplished Combat pilots. In and of itself, winning one Sportsman event may not indicate the need for a move. However, the combination of a win (or wins) and obvious skills beyond those of a beginner should qualify a pilot for a move to a higher skill level.
  • Advanced competitors have some proficiency or experience flying Combat. They may be fairly new fliers who have competed at the Sportsman level and developed their skills to a point that indicates they are ready to move to a higher level. Advanced is intended to provide both an intermediate skill level for pilots who have developed past beginner levels, and a venue for folks who might otherwise never win and thus lose interest. Advanced provides a place for the competitor who wants to fly, and occasionally win, combat matches, but does not care to compete with the furor and dedication necessary to win against competitors aiming for a World or National Championship. Advanced is also intended for former competitors returning to the sport after an extended layoff. These fliers may quickly move to the Expert class; however, flying for a time in Advanced while their former skills and equipment return increases the probability of success beyond that likely experienced flying against the Experts.
  • Expert is the premier competitive class representing the highest level of combat proficiency.

Section 2: Pairing & Class Movement: Generally, Sportsman contestants may be matched against Sportsman, and Advanced against Advanced, in the first matches of a contest. When the Sportsmen have flown each other, those still in the contest continue against Advanced fliers, and so on. Prizes may be awarded for the highest-placing contestant in each class as well as the overall winner. Contest Directors may also choose to completely separate the classes.

Movement from Sportsman to Advanced, or Advanced to Expert, is not based on a set number of match or contest wins, but rather on more subjective criteria. If a Sportsman begins winning against and finishing ahead of Advanced pilots, it is appropriate to move up; likewise with Advanced moving to Expert. A voluntary move to a higher skill level can be made by the individual and is the customary method of movement. Movement down should be rare, but may be granted with the permission of a Contest Director. A contestant may fly in a higher skill class at a contest where their regular skill level is not being flown without permanent commitment to the higher class.

Section 3: Pilot Responsibility: In MACA Skill Classes, it is the responsibility of each individual to track their own skill class level and declare it when entering contests with skill class divisions. If a skill class is not declared, that pilot will be placed in the Expert class for that contest.

Section 1: Every person who is, will be, or has been an elected or appointed Officer of MACA and their personal representatives shall be indemnified by the corporation against all costs and expenses reasonably incurred by or imposed upon them in connection with or arising in whole or in part from any action, suit, or proceeding to which they may be made a party by reason of being a past, present, or prospective Officer of the Corporation or any subsidiary, affiliate, committee, or other subpart thereof, except in relation to such matters as they shall be adjudicated in such action, suit, or proceeding to have acted in bad faith, and to have been liable by reason of willful misconduct in the performance of duty on behalf of the corporation. Costs and expenses as used herein shall include, but not be limited to, attorney's fees, expert witness fees, and other attendant expenses of litigation or arbitration, damages awarded, or amounts paid in settlement.

Section 1: Any active member or any Officer may propose amendments to these Bylaws by submitting the proposed amendment to the President at any time. Upon such submission, the President must present the proposed amendment to the Board within 7 days, and the Board shall determine if the proposed amendment should be presented to the membership, and if so, the exact wording thereof and time of presentation.

Section 2: If a proposed amendment is rejected by the Board, a written letter of rejection is to be sent to the proposer within 7 days of the Board's final vote on the proposal.

Section 3: All proposed amendments and action taken thereon shall be reported to the membership in the next issue of the newsletter following receipt of the proposal.

Section 4: Presentation of a proposed amendment to the membership shall be made in the newsletter, and adoption thereof shall occur only upon a favorable vote of a two-thirds majority of those members responding.

Section 5: After an amendment has passed, a complete updated copy of the Bylaws will be printed in the following month's newsletter.

Section 1: Gender Case: The use of any gender case in these Bylaws is in no way restrictive and applies equally to all genders.

Section 2: Non-Discrimination: MACA will conform with all federal ADA rules and regulations and will not knowingly discriminate on the basis of race, creed, color, religion, or disabilities.

Section 1: These Bylaws shall become effective upon an affirmative vote of a majority of the votes received by the Newsletter Editor within one month of publication.
