All gliders must have marking on the nose, the leading edge of the wings, the undercarriage doors and other suitable spots. When putting the marking on, have in mind that as much as possible of the markings on the wings are on the leading edge, not over and under the wings. See picture on the right for some well marked gliders.
The markings we provide is MACtac 8054 by MACtac Scandinavia AB in Malmö (phone +46 40 680 31 30, http://www.mactac.com). Local dealer in Oslo is Basberg Papir.
The reason for putting on the markings is of course to be seen. There will be many white gliders, lots of white clouds and white mountains as far as you can see.
