First two rounds 240 seconds, then 3 rounds of 180 seconds followed by two rounds of 150 seconds due to wind direction and thermal activity carrying models into the town of Kozlany.
Interruptions and delays
None. Free lunch was served for the contestants.

Any incident or accident
The contest director and jury decided for a late 8 minute fly off with altimeter as back up should the max be attained by more than one pilot. In all classes all models landed on the field except for the top 2 flyers in F1A. The runner-up model landed in a tree at the edge of the village and the eventual winner landed also in a tree some 3.2 km downwind behind the village as the model glided in a straight line downwind. Both these pilots could not present their altimeters to the jury and got the altimeter data via radio link from the model up in the tree. As it was clear to the jury the models did in fact perform the claimed time, these results were accepted (albeit not according to the sporting code which states the altimeter itself must be presented and read within one hour after the fly off).
Several contestants used their certified altimeter to contest the time keeper’s recorded time. All altimeters could be read and most times were upwardly corrected as models disappeared behind an elevation in the field. The winner eventually landed some 30 meters lower than the launch elevation, which explains the substantially higher flight time in the dead air conditions.
