I hear on the grapevine that Graupner have fallen out with Ripmax big-style. Gliders have been importers of Graupner stuff for a long time now, although their main thing is RC model aircraft. You may well find that they start to offer more Graupner stuff at sub-Ripmax prices, so it would be worthwhile sticking this website on your Favourites list.
Suit yourselves, but you heard it here first!
