Inter-Ex is the name of a number of events with a long tradition. These gatherings of lateral thinkers are held under the headline: It flies, which no-one believed! It is not very important to show high class performances, although these are presented almost each year. Inter-Ex is pan-european. In the future the events will be held rotational in France, Netherlands and Germany. Maybe Suisse will be added to the list in future. I participate in Inter-Ex since 2004. So i'am one of the new addicts. Most participants know each other for many years and build a strong group of knowledge and common sense, but newbies like me get a warm welcome. A wonderful documentation of the history and idea behind these events is on the official site of Inter-Ex. Welcome to Inter-Ex. It is impossible to show it all, therefore i show you just a small selection of pictures.

The Boomerang was my entry for Inter-Ex 2004. It is basically a flat circle wing with ailerons. The whole construction is built as transparent as possible, except the boomerang, which turns inside the structure. Motor is a homebuilt Doubleconrad. The Boomerang itself is driven by a micro brushed motor which acted in his first life as a door-opener in a CD-rom drive. I was inspired to build this by a poem from Joachim Ringelnatz, which is well known in Germany.

Pegasus was planned as my entry for Inter-Ex 05, but i didn't manage to get the build finished, because it shows an enormous need for power and i was lacking time to wind a hotter motor. Pegasus is mainly build from foam-bathing-noodles for children with a rogallo-wing from carbon-rods and kiter-nylon. Rudders are made of 6mm Depron. I will try to get Pegasus ready for Inter-Ex 06 in the Netherlands.

After Inter-Ex 2007 i was really amazed by Peter Löhnerts experiments with thrust-vector-steering and as well impressed by the beauty of Gerard Jumelins new Mobil'Air models. It was a only a short step to combine both ideas, but a longer way to make it a good flyer. Needed some consultations with Peter and Gerard. Now it flies perfect, if it's calm. Wind is a no-no for this plane, because you need much thrust to keep it against the wind at windy conditions, but then it climbs strongly.. :-)Phantasie has some major modifications with respect to Gerards outstanding design. So i decided to use another name, because it is not a Mobil'Air anymore.Visit my slowfly-subpage for more of Gerards work or my links-subpage to find a link to Peters homepage crazyplanes.de .

The big Rumpelstoss is my model for Inter-Ex 2008 and is just a bigger version of the small Rumpelstoss, plan here: Slowfly. The big Rumpelstoss has 226 cm span and weighs 2780 Gramm. Big Rumpelstoss is made from Depron, a little bit of spruce and a few homemade thermo-vacuum-formed plastic-parts. Motor is a Dualsky Outrunner 4240-10T with 3S 3200 Saehan lipo. There's a nice german thread with a short, just slightly faked backgroundstory :-) : Rumpelstoss bei RC-Network

The Flying squirrel is a real eyecatcher. It's a design by my friend Lutz Näkel. After having seen his prototype i was completely hooked. He made another one and i got it as a present. Thanks, Lutz! :-) The Flying squirrel spans 35 centimetre and weight is 60 gramm with a 10 gramm brushless and 2s-300 lipo. It's ok indoor and outdoor and can even stand wind. Flighttimes are around 10 minutes. Have fun with the build and flying. Please note, that this is not for absolute beginners, some advanced piloting-skills required.
