C. RACING COURSE AND PROCEDURE

1. COURSE DIMENSIONS
2 pylons will be setup on the competition date, in the interest of safety to suit existing field conditions. The method of flying the course will be anti clockwise. It is the responsibility of the contest director to ensure the accurate positioning of the base pylon marshals relative to the flight path of the models.

2. STARTING PROCEDURES
a. The race will consist of 4 competitors minimum and ten laps of the course will be flown per flight.
b. Models will be hand launch from behind the start line.
c. Model will be launched only upon the launch signal given by the contest/line director.
d. One minute will be allowed for starting engines although the starter may commence the race if he is satisfied that all competitors are ready to launch before the one minute start time has elapsed.
e. A total of five minutes will be allowed for the race, any entrant who does not land his model within this time will be disqualified.
f. A model must not be launched or re launch after a period of 30 seconds from the start of the start of the race has elapsed. If a competitors model has not taken off within 1 minute of the start of the race the competitor is disqualified from the race and re run of that race.
g. A competitor may only retrieve his model after the race has finished and all other models in that race have landed.Pilots and their callers must stand behind the start line at all times during a race.

3. DANGEROUS FLYING
Low flying is consistent flying below pylon height which endangers officials or other competitors. The contest Director may give a competitor a warning for low flying, if the competitor continues to fly the Contest Director shall disqualify him/her from that heat. At the contest Director’s discretion he may disqualify that competitor from the heat or the event if he thinks the competitor is flying dangerously.

4. SCORING
a. There will be a minimum of 2 flights per participants, will be decided by the contest director on the competition date. The best of N-1 heats will be taken into consideration (N being the number of heats completed in the competition).

b. Points shall be awarded after each race as follows: The competitor’s score is his corrected time in seconds to the first decimal place. A pilot cutting a pylon (flying inside) will have 1/10 of the ten laps’ time added to the ten lap time. Two cuts in any race will cause the pilot to be disqualified from that race.
c. If the competitor fails to complete his flight or is disqualified the score shall be 200.
d. The winner of the event is the competitor who has accumulated the lowest score after the conclusion of all races.
e. If the time permits, and there is no frequency conflict, ties shall be broken by a fly off race. Otherwise, the best single race score shall be considered in resolving a tie.

D. ENFORCEMENT OF RULES
Enforcement of announced race rules is the responsibility of the Contest Director, whose authority is absolute.
