1 Model description

My interest in flying wing aircraft was aroused many years ago. The MODEL book "Flying wing 
sailors remote controlled" by Reinhard H. Werner and something later showed the FMT specialist 
book “Fascination Nurflügel” by Hans-Jürgen Unverferth Paths and wrong turns and helped me to 
design flying wings that fly well. Much has developed since then, but just as much had already 
proven itself back then and has been incorporated into the Res-Dart construction. A rectangular 
wing with a relatively large wing depth as with the CEOZWO, much set as with the free-flight 
arrows in the middle of the 20th century. Century, sufficient sweep and rearwardly offset winglets, 
as they were already Curt Weller in the 1980s with his Elfe 2, formed the basis. Has been completed
the concept with a specially designed profile and through the use of DSA Marginal arches. I can do 
it for anyone who wants to take a closer look at DSA pipes Homepage www.zanonia-flyers.de by 
Reinhard Sielemann and Dr. Hans-Jürgen Unverferth recommend. Research work was carried out 
by them with great effort and also published (e.g. AUFWIND magazine 5/2016). 

RES-Dart is a dart wing that complies with the German F3B-Res regulations and with Res 
competitions can be used. It was specially designed for this purpose designed and constructed. The 
high starts should be done with a Res high start set under consideration of the typical rubber tension
and the class-specific one wind conditions. The profile used was specially designed. In the profile 
construction value was placed on a very high maximum lift and good buildability. The thickness of 
approx. 9.5% enables light spars and offers good torsional strength. Only in the area of the front 
panelling, the profile contour is a curve. On the rest of the profile Similar to the AG35, flat 
segments prevent the covering from collapsing between the ribs. The chosen wing geometry and set
were already practically checked and flown during the design phase. An important design goal were
good rubber rope high starts. The flight tests showed problem-free take-off behaviour and the 
attainable starting altitudes proved to be very competitive. The RES dart has due to its wing profile, 
the low wing loading and the DSA winglets extremely good-natured flight characteristics that 
enable experienced RES pilots to get close crank out floor thermal systems and sometimes even 
close the thermal connection by hand find. Have fun building the RES-Dart and wish you all the 
best for your first flight.
