F1A
F1A gliders - projected surface area 32-34 dm2, minimum weight 410g, towline 50m. Historically also known as A/2 Nordic gliders. The gliders are launched with 50m towlines, the tow hook allowing models to be flown in circles while searching for thermals during towing. The highest performance models are accelerated to high speed before release from the towline, resulting in a climb and bunt which can gain an additional 50m above the towline height.

B.4.22 Surface area
The surface area includes the total surface of the wings and that of the horizontal or oblique stabilising surface or surfaces. The surfaces taken for calculation are the orthogonal projection on to a horizontal plane of the surfaces in question with each surface at zero incidences. When wings or stabilising surfaces are built into the fuselage of the model aircraft the surface taken into account shall include that area contained within the normal contours of the flight surfaces extended so as to meet at the plane of symmetry of the model.
