2009 ARF Sport Class Rules and Regulations

PILOT:

This class is intended to introduce pylon racing to experienced pilots wanting to race.  This class is a stepping-stone for learning two pylon racing with the same trainer used for learning to fly, and moving on to faster aircraft.

AIRCRAFT:

The aircraft must be a high wing tricycle gear “STOCK” ARF trainer intended for .40 size engines. The following modifications may be made:

1. The wing may be bolted on.
2. Trainer may be recovered so long as it is still recognizable as an ARF trainer.
3. The engine mount and the hardware used to attach the engine mount may be non-stock.
4. An antenna tube may be used.
5. Repair of previous crash damage is allowed.

     REQUIRED EQUIPMENT:

1. The fuel tank need not be stock, but must have at least the fuel capacity of the original tank.
2. Three wheels at least as large as the original wheels.  No tire modification is allowed.
3. Any .40-.49 size two cycle engine may be used.  A muffler must be attached.
4. Propeller APC 10 X 6 must be used for the race.
5. Spinner or AMA safety nut must be installed.
6. Be able to stop the engine by radio or demonstrate an idle slow enough that an unrestrained aircraft does not move.
7. Have separate controls of all three axes and engine of the aircraft.
8. Pilots AMA number must be on the right wing minimum 1 in. high, or on an AMA sticker affixed to the inside of the aircraft. 

RACING:

1. The racing will be conducted on the same course and generally in the same manner as Two Pylon Racing.
2. All aircraft will be checked for construction, and radio equipment installation during the safety check prior to racing.  Bring your aircraft to the safety check with the wing off.
3. The start of each race will be a fixed start. The CD (Contest Director) will advise when to start your engines. You will have 2 minutes to get you plane started and in the air. The CD will then start a 1 minute count down. At the count of zero, you must behind the start finish line. Any plane that is over the start finish line will be down 1 lap. In the event of all planes crossing the start finish before the count of “0” the race will be re started.
4. If a pylon is cut, the pilot will be down 1 lap. If the same pilot cuts a pylon twice, he will be given 0 points for that race and receive a DQ.
5. Winning aircraft of each heat will be required to restart at the fight line. The engine at high throttle, high throttle trim, with carburetor at full open, and the needle valve setting used for the race, the RPM will be checked.  Any engine that turns more then 13,500 RPM will be disqualified from that heat and receive “0” points.
6. You may use any fuel of your choice.  (No fuel will be supplied)
7. There will be 3-4 pilots per heat. Each race will be 10 laps.
8. 3 points for 1^st. 2 points for 2^nd. 1 point for 3^rd. 0 points for DQ & DNS.
9. Each pilot shall have a holder/caller.
10. Heats may be filled to assure that the most number of racers are in each heat, without regard to a previously determined matrix.
11. Different pilots may fly the same aircraft.

ANY AIRCRAFT NOT COMPLYING WITH ABOVE REQUIREMENTS MAY BE ALLOWED TO COMPETE AT THE DISCRETION OF THE CONTEST DIRECTOR, IF HE DETERMINES THAT THE NON-COMPLYING AIRCRAFT HAS NO SPEED ADVANTAGE OVER COMPLYING AIRCRAFT.
