Hans-Jurgen Unverferth found a love for flying wings after watching a friend struggle with a tailless model on a slope long ago. He has since with John Yost and Reinhard Sielemann designed a large number of wings which have been gradually more successful. Be aware that some flying wings are attributed to them which they have had nothing to do with. Here are some of the many that I KNOW that Hans-Jurgen has had a hand in the development of.
Pirx, Just in Time 1, Just in Time 2, The CO2, The C02 Actor, The C02 mini, CO3, CO4, CO5, CO5 mini CO6, C07, CO7 hlg, C08, CO8 1/2, The X-stase electric pylon racer, The joined 1 and 2 speed models.
More of these models will be added to these pages as the information becomes available
Here is the full translation of the article written by Hans-Jurgen about the development of the CO2. Thanks to Klaus Mittendorf for the translation.
This model uses the mh45 section and is the best all around model that Hans-Jurgen thinks he has made so far. At home on the slope and the flat.If you are going to build a first wing that works well, with simple construction, this is the one to go for.
The CO6 marked a new era in design direction with the use of Reinhart Seilemann's new Airfoils.
The RS series are designed specifically for Tailless models and these helped greatly in new levels of performance.

THE CO7This model did away with the center boom and has been met with considerable success. It launches hard and thermals easily. It has outlaunched Ellipses and V-Ultras and has won F3j events against conventional models. It also has a movable c.g in a later modification.

So you want a fast slope plane? Just HOW fast did you want to go?
THE CO7 HLG
The Co7 hlg came about from the development of a hlg out of the components that were available at the time. On the table were two Volz servos and a 500 mah battery pack. The result is also an outstanding slope model with a wide wind range. It is also quite at home being catapult launched.
The Co8 is a smaller lighter wing. Calculations say it is to be something special! Here are the first and second evolutions of the type.
