Model processing was carried out on the day before the first competition. In contrast to the requirements of the CIAM Sporting Code, models were marked with one sticker on the fuselage and one sticker on the wings. A towline check was provided but there were no scales for competitors to check the weight of models or rubber motors. A scale was provided during the competition days and competitors were able to check model and rubber motor weights. Random processing was carried out on each competition day on at least 20% of the competitors. The competitions were scheduled to start at 7.00 with seven rounds of 55 minutes and a 5 minute break. On the first day F1A started a few minutes late since here were not two timekeepers at each starting position. In order not to have a lengthy delay, the Jury allowed team members to act as second timekeepers at the poles with only one timekeeper. This did not last for long and soon there were two timekeepers at every position and this continued for the remainder of the championships. F1A was flown to a maximum of 240 seconds in rounds 1 and 2 and 180 seconds for the remaining five rounds. 6 competitors had a full score and, after an afternoon break, these assembled in the evening for the first flyoff at 18.45 to a maximum of 360 seconds. This eliminated two flyers and the remaining four attempted 480 seconds in the second flyoff at 19.30. This gave a clear winner, with all models clearly visible for the flights. F1B started at 7.00 as scheduled and followed the same maximum flights times used for F1A. The same number (6) reached the flyoffs which were held to the same schedule. Two flyers took part in the second flyoff and the winner achieved the 480 second maximum. F1P started at 7.00 and followed the class rules of having seven flights all to a 180 second maximum. The winner was the only person to achieve all seven maximum times and no flyoff was necessary. The models of the winners were checked each day and all passed the checks.
