About CAD+Modelltechnik Jung
CAD+Modelltechnik Jung is a CAD service company in the Rhine-Main region headquartered in Hünstetten-Limbach. Owner Dipl.-Ing. Volker Jung offers product development from individual components to complex assemblies, the creation of standard-compliant drawings, and prototype construction from the first idea or sketch — all from a single source. Design work is carried out with SolidWorks and SolidEdge; experience exists in the fields of plant and mechanical engineering, apparatus engineering, model making, aerospace engineering, and UAV systems. In addition, the company distributes in its online shop self-manufactured rotor blades made of aluminium (VIPER-X76) and carbon (VIPER-C80) for model helicopters, rotor heads, swashplates, helicopter mechanics, as well as construction plans for model engines and its own CNC milling machine. Manufacturing licenses for industrial helicopter drones (including Koax X-252, Koax X-342, Dragonfly M35/T50, Dragon-50 V2) and the distribution of Jakadofsky turbines complete the portfolio. For in-house production, a CNC milling machine CNC-Rev3 with travels of X=745 mm, Y=275 mm, Z=100 mm is available.
