The competition is basically based on the FAI F9 rules. The qualifying order will be determined by the best three consecutive lap times. The format of the competition will be TOP32 DKO. The final races will be CTA based up to 2 winning rounds. The results of the 2-4 finishers will be determined by the scores they receive for their positions in the CTA. In the event of a tie on points in any of the placings, the last round placing will decide.

Supplementary rules:

Only aircraft equipped with a circular polarised VTX antenna may fly

Re-run:
In the event of a mid-air before the 2nd obstacle on the course, if any aircraft is grounded, the race will automatically restart. If no aircraft is on the ground, but one of the aircraft is clearly at a disadvantage (the pilot knows this, the organiser may not be able to see it from the outside), he can request a rerun if he does not continue the flight, but lands after the mid-air and signals the organisers. All other cases will be dealt with on an individual basis.

Early start:
Attention! Early start during the DKO stage means automatic disqualification from the round. (F9U 2023/02)
