Racing Rules for Electric Pylon Race
(Preliminary, to be modified if necessary)

Model specification

  • Wingspan less than 1 meter (38”)

  • Battery: 2-cell LiPo (7.4V) or 7-cell NiCD/NiMH (8.4V)

  •  Motor: limited to S400 (brushed or brushless)

  • Each contestant can register a maximum of two planes

 Course

  • 100m course with two poles (base A and base B)

  • 10 legs of a total of 1km, i.e., 5 circles, counterclockwise track (top view).

  • 3 planes race simultaneously.

  • Racing planes must fly below the top point of a pole (10m height) when they are passing the judges.

  • Pilots stand at base A, one or two judges in base A for monitoring the passing of all planes

  • 3 judges in base B, each monitoring the passing of the corresponding plane in base B. Indication of passing is by turning on the corresponding LED (RGB), pass is ON, cut remains OFF.

  • This is not a timing event. The plane who first completed the course won the race.

  • Pilots will be given 10 seconds count down time to launch, to prepare and to stabilize the planes before passing the Start point. The start point and end point is in Base A. As similar to F3F, planes are not allowed to cross Base A in this initial 10s period, otherwise it will be a false start and result in disqualification (DNF).

  • If a pilot has two cuts, he can continue on the track but he got a DNF score at the end.

  • The race is organized according to a race matrix, all participants will be divided into groups of equal number, groups will race according to the matrix in consecutive (alternative) order to minimize the waiting time of each pilot (see the arrangement below). The top pilot(s) of a race group will be promoted to next level of competition. A draw will be conducted before the contest to decide the groupings.

  • Scoring is similar to MOM, the first finished gets one mark, second gets 2 marks and DNF get N+1 marks, where N is the total number of pilots in a group. The total marks for all races in a group will determine the position of pilots in that group.

The following picture shows the actual arrangement for the Lamma Island flying site:

  • If  an extra set of lights is available and with sufficient manpower to man the lights, the pilot positions may be located at the center of the track instead of being biased towards Base A.
  • The contest is conducted according to a tree structure with elimination as shown:
