There were made a separate starting line for F1B, F1Q and F1S

Number of competitors per pole

Not required

Local rules or deviations from Sporting Code

Competitors were timing each other (1-2 timekeepers). Timing check was randomly performed on the starting line by the contest organisation.
The Contest Directors decision of flight time in all fly-off’s, as deviations from Sporting Code, were discussed and accepted by all competitors.
A change of wind direction to come from west immediately after first fly-off in F1A, had the consequence, that the distance to the border of the field were reduced to 6-700 meters. For this reason, the contest director decided, and announced, to held the second fly-off round as a “dt fly-off”, where dt-time was measured after 60 sec. flight. One of the two competitors announced that he would not to participate in the second fly-off, for which reason, it then was decided to held the second fly-off as set in sporting code.

Observations on timekeeping

Random check of timekeeping from organisation-members.
Generally no problems and good visibility.
During a lack of qualified timekeepers for fly-off, the organizer accepted the use of only 1 timekeeper per competitor.

Any incident or accident

At morning breefing, all F1Q pilots were invited to use the official SET (Joule-Tester) for self-control.
Prior to flyoff (which was agreed with 2 joules / grams and a maximum of 20 seconds engine time) voluntary tests were conducted on 4 flyoff pilots. The 3 Danish participants were all tested OK. Including Per Grunnet, which uses standard SIDUS limiter. Several of the other participants also used SIDUS limiter. In the 4. model tested the SIDUS limiter was also set to the correct value (equivalent to 2J / g) - but SET showed that 61 Joule was used more than allowed.?? Participants became aware of the reason - which was that in that model, SIDUS limiter delivered the stop-signal to the model's Timer that were connected to the ESC. BUT the timer responded slowly to this stop-signal - resulting in the measured overuse. The pilot immediately reduced the SIDUS limiter setting with the 61 joules so that the flight-off flight was settled according to current FAI rules.
