RES Dart Flying Wing (1920mm) Kit

The RES Dart is a superb 2m flying wing that incorporates very advanced aerodynamics to provide astounding performance. The RES-Dart is unusually stable for a flying wing, has good thermal performance and a wide speed range. The model impresses with its balanced flight characteristics, the enormous performance potential and the extraordinary manoeuvrability (see following video). The large 2 piece spoilers enable steep descents, allowing safe exits from thermals and accurate landings. The wing is two part and the winglets can be detachable, making for a very transportable model. Like our other F3-RES models this is a high quality build-it-yourself kit constructed from hand selected CNC cut balsa and plywood

RES-Dart is a flying wing which complies with the German F3-RES regulations and can be used in these competitions - in fact it has been specially designed to be competitive in these events. The wing profile has been optimised to give a very high launch while at the same time being easy to build. The thickness of approx. 9.5% allows for a lightweight structure and provides good torsional strength. The contour of the profile is only curved in the region of the front Dbox. To the rear of this, similar to the AG35, planar facets prevent covering sag between the ribs and thus ensure an accurate section is maintained. The wing geometry and sweep have been practically tested and flown many times while optimising the model's structure and aerodynamics. One important design goal was good launching. The flight test showed a smooth launch behaviour and very competitive launch heights. Thanks to its wing profile, low surface load and DSA winglets, the RES-Dart has extremely good-natured flying characteristics, which enable practiced pilots to crank up the RES-Dart into the tightest thermal turn and sometimes even get away from a hand launch.

The winglet mount incorporates a Druck-Sog-Ableitung (DSA) tube. DSA means pressure-suction discharge and improves the flow conditions in the wing-winglet transition area. This is a major cause of the very good-natured behaviour and the controllability in slow flight. The DSA tube was originally a light carbon fibre tube but this was decreed to exceed the limited amount of carbon fibre allowed in the German version of the F3-RES rules. Consequently the model is offered with a carbon or a plywood tube which is nearly as light and complies with all interpretations of the rules.
