The Swedish indoor championships 1998


The 1998 Swedish indoor championships took place in Örebro, and was organized by the Nimbus modelflying club, this year celebrating its 50th anniversary. The duration classes showed an increase in entries compared to previous years, while in peanut numbers were down somewhat.

Manhattan Cabin

This class has never before been flown in Sweden, so it came as a surprise when it was included in the competition invitation. Lennart Lilienberg built a model which was ready just in time for the competition, I built a model which was not. We both found it difficult to come anywhere near the minimum weight. Ingvar Persson and Ove Carlsson from Skåne had models covered in ordinary japanese tissue, which were probably even heavier. All the models were flyable, but the gap between the winner Anders Sjöberg and the others was large.

F4F Peanut

The entries in peanut were a bit lower than they have been previously in Örebro, and most of the models had been seen before. One person on whom one can rely on to bring something new is Lennart Lilienberg. This year he had a biplane racer built in mixed foam/balsa, and a Miss Los Angeles racer built in traditional stick & tissue technique. The biplane racer needed more trimming and had to be put aside, but the Miss Los Angeles flew very well from the beginning, and in addition got the highest static score. Another new model was Gustav Enebog's Sukhoi. At 18 grams it is rather heavy for a peanut, and must be difficult to trim. In spite of that it proved stable enough, but would have needed more space. It flew better the next day; outdoor this time. The winner was my Drzewiecki Canard, which got the highest duration.

This class has only had 3 competitors for the last few years, but this year the number of entries was almost doubled. Jonas Romblad and Tomas Leijon flew EZB:s, but were not far behind the "proper" F1D:s. Sven Pontan had bad luck with his flights, while Lars Lindén did a couple of safe flights with his quite old model to win the competition.

This class was dominated by the Haninge club, with both Romblad, Hultgren and Pontan making flights over 10 minutes. A newcomer to EZB was Tomas Leijon, who had built an original asymmetric model with a quite short tailboom length compared to usual practice, and got good results from it.

This is a Swedish equivalent to the continental F1D-beginner class. Since some years Jonas Romblad have had the habit of winning every 50-öres competition he enters, and no one was surprised when he yet again emerged as the winner. His model has a very large chord to take full advantage of the rules, the covering is on the underside of the wing, and wing tip end plates are fitted. Read Romblad's own account of his experiments, and the merits of upper/underside covering,.

The winner of this class was Birgit Törnkvist, whose Wittman Racer flew about half a minute longer than anyone else. Especially worth mentioning are also Lennart Lilienberg's gigantic Mongster racing biplane, and Lars Tolkstam's de Havilland Hornet (a derivative of the Mosquito). The Mongster weighs about 12 grams if I remember correctly. Nontheless, it made flights over 2 minutes. Tolkstam's DH Hornet was especially well finished, and despite having two rather short motors it flew without problem for a duration of about 1 minute.

Miniflyg is a competition for Delta Dart (Flugan in Swedish) and other similair models.
Daniel Brånn knows how to get the most out of a Delta Dart. He got the best single flight, 80 sec, and won the junior competition. His total result was actually one second ahead of Olle Blomberg, the senior winner.
