CIAM Flyer (1-2021) - Coaching in Aeromodelling
In recent years, sports coaching has become increasingly important. In competitive sport, a significant proportion of success - or failure - is accredited to coaching. As it's not just physical performance that is important in aeromodelling, but particularly precision and the ability to concentrate, coaching methods vary.
CIAM Flyer (6-2020): György Benedek, the pioneer of airfoils for low Reynolds numbers
Once model aircraft design had progressed beyond single-surface wings covered with oiled silk in the mid-1920s, almost all model wings used airfoils developed for manned aircraft, which operated at much higher Reynolds numbers than any model. Sections like RAF 32, NACA 6409 and Clark Y were typical, often 12 or 14% thick.
The person who did the most then to produce airfoils suited to flight at low Reynolds numbers was the Hungarian György Benedek.
CIAM Plenary Meeting completed online
The Plenary Meeting of the FAI Aeromodelling Commission (CIAM) took place online on 14 November 2020.
Traditionally, this event is held in March or April at the FAI Secretariat; previously in Paris, France, and now in Lausanne, Switzerland. This year was to be no different, but the COVID-19 outbreak decided otherwise.
