1) Four attempts (total) will be allowed for two official flights.   Note: this is not the same as four attempts for each of two officials.   Be sure you understand the difference.

2) Score will be based on the best speed/lowest time of the two official flights.

3) The slower of the two official flights will be used as the first tiebreaker. The most laps completed in an attempt is the next tiebreaker.   A fly off will be used as the final tiebreaker.

4) The contestant has three minutes to enter the circle, start the engine, and launch.

5) Models may be hand launched or ROG from prepared surface at the competitor’s discretion.

6) Models will be timed from the first pass over the start line until completion of 12 laps (1/2) mile.

7) Maximum flying height is 20 ft.

8) Electric starters may be used.

9) AMA CL Speed and CL general attempt definitions apply except as listed here.   Failure to launch in 3 minutes is an attempt.   Failure to complete required laps is an attempt.   Failure to get or remain airborne after launch is an attempt regardless of how little distance traversed/flown and/or regardless of whether or not the 3 minutes is up.

10) Successful launching and completing the 12 laps constitutes an official flight.   Flying high may, at the discretion of the Event Director, constitute a no-score official.   Note: a no-score official is not as severe as disqualification. (Disqualification, as a minimum, throws you out of the event as commonly interpreted by AMA CDs, and a literal reading of the AMA rulebook requires throwing the entrant out of the contest.)

11) Deliberate crashing, in the opinion of the event director, to avoid an official flight, will constitute a no-score official.

1) Models will be flown in a series of heat races leading to a final race

2) Races will consist of two or three models.

3) Each contestant will fly two heat races.   The best (lowest) time from the two heat races will determine each contestant’s score.

4) The three entrants with the best heat scores will fly a final race.   If there are eight or more entrants, the four with the best heat scores will go into the finals.

5) Ties will be broken, if necessary to get into the finals, by using the other heat scores, else most laps completed for the other heat, else a flyoff heat.

6) Final standing will be determined by the time required to complete the main event final race, then laps completed if not everyone completes the finals.   Finals ties will be broken by best heat scores.   Best heat score ties will be resolved as described in item 5 above.

7) Races will begin with all engines stopped.   At the starting signal, engines will be started, and the models may be launched as soon as the models/pit crew/pilots are ready.

8) Timing will begin at the starting signal and continue until the model has completed the required number of laps, and pit stops, for the race being flown.

9) In the heat races, 30 laps (1.25 miles) and one pit stop is required.   In the final race, 60 laps (2.5 miles) and two pit stops are required.

10) Landings, or crashes, with the engine running will not be counted as a pit stop.

11) At each pit stop, the model will land, be refueled, the engine restarted, and the model launched to continue the race.

12) Models may be hand launched or ROG

13) If the required pit stops have not been accomplished before the required number of laps is completed, timing will continue until the model has completed one full lap following the last required pit stop.

14) Each contestant may act as either the pilot or as the pit crew who starts the engine and launches the plane.   Points scored will go to the individual who entered the plane in the event.

15) Specific requirements for conduct of pilot and pit crew will be discussed on the day of the race.   All requirements are as specified in the CL Racing Unified Rules in the AMA rulebook except as otherwise modified here.

16) A person who causes a line tangle/midair/crash of someone else’s plane is to forfeit the heat or final.   The CD or ED is to determine to the best of their ability the responsible person. The remaining persons in the heat or final get to refly the heat or final.   If it was a final, the next best person from the heats gets to advance to the final for the refly.  If it was a heat the CD or ED may replace the person who forfeited the heat and reschedule the heat.   A forfeited heat has no score, counts as a heat, and does not qualify for participation points.   The CD’s or ED’s opinion is final and is not subject to appeal.   (Per the AMA rules)

17) The ED may require any entrant to prove he is capable of flying in a multi flyer event before being permitted to do so.   The ED is expected to require such demonstrations to ensure the safety of all when he suspects such inability.   An ED should not allow persons who have demonstrated (either in a requested demonstration or in an actual heat) that they are incapable of flying in a multi person event to do so.   Such persons may still serve as the pit crew for their entry.   The ED’s opinion is final and is not subject to appeal.   (Per the AMA rules)

18) Fast fills, hot gloves, hot fingers, pressurized refueling systems, and similar devices intended to decrease pit stop times are prohibited.   Electric starters and 1/2A spring starters, mounted on the engine, are permitted.

19) Two timers/lap counters will be used for each plane flown in a race unless the CD determines there are only enough people available for one each.

20) Attempts, in the usual sense, do not apply to racing events.   Each contestant gets one chance to complete each heat or the finals.   If completed a time will be recorded, else a "DNF" and the number of laps will be recorded.   "DNF - 0 laps" is a possible score.

21) If an entry is not started and launched within 2 minutes after the race starts for the heats, and within 4 minutes after the race starts for the finals, a "DNF - 0 laps" is scored for that entry.

Scoring, attempts, conduct, rules, responsibilities, everything, will be exactly like AMA precision aerobatics except as is otherwise defined here.   As these planes are old designs, the maneuvers are somewhat like old time stunt.   There are also a couple of optional "tiebreaker" maneuvers.

1) One level lap will be flown between maneuvers.

2) There is no penalty for running out of fuel once.   Simply refuel and continue where you left off.   The CD may, at his discretion, allow running out of fuel twice or three times provided that time permits.   This decision will be made and announced prior to the start of the event.

3) Launch will be ROG from prepared takeoff area, or hand launched, at the competitor’s discretion.

4) Electric starters may be used.

5) Three attempts (total) will be allowed for two official flights.   Note: this is not the same as three attempts for each of two officials.   Be sure you understand the difference

6) Stunt scoring is by maneuver.   Higher is better.   Your score for each official flight is based on the sum of your points for each maneuver.   Your placing for the stunt event is based on your best offic1al flight.   The maneuvers and their point ranges are listed below:

Starting and launch within three minutes      0 or 5 points

Launch and level flight (2 laps)      10 - 40 points

Wingover (not reverse)      10 - 40 points

Climb and dive (Like old time stunt - steep climb, one lap high, dive back to level at same place climb was initiated)      10 - 40 points

Two inside loops      10 - 40 points

Approach and landing      10 - 40 points

Optional Maneuvers

If modeler wants to attempt to gain additional points, tell the judges before you fly and include these after the inside loops.

One outside loop      10 - 40 points

Two lazy 8’s      10 - 40 points

(These rules were created by the Northern Virginia Control Line club and are presented here in a slightly modified version.   A big thank you to this great group for creating this idea and bringing it to reality – RJK)
