Besides the center of gravity, the EWD (setting angle difference) must be correct if the model is to fly well. Inaccurate settings quickly lead to countless test flights or immediate crashes. With the EWD scale, this uncertainty can be avoided during the first flight. EWD measurement with prism or plug gauge:

Features:

• strongly curved profiles (no measuring error due to plug gauge)
• T-tail, cross tail unit
• V-tail (by swivelling prisms)

The following useful measurements continue to be possible:

• Rotor blade adjustment for helicopters
• Engine camber measurement for combustion engines and electric drives
• Testing of settling or distortion of wings
• Adjusting the model at the start (position of the wheels)

Since their founding in 1958, Multiplex has developed top RC Radio Systems for the RC Industry! With the current 2,4 GHz Technology M-LINK and telemetry system, Multiplex has put itself in front of the RC Industry in Germany. Since the early 2000s Multiplex began producing finished models made from Elapor, a high-tech particle foam, which setted a milestone im the RC Airplane, as well as in the Helicopter (Funcopter) sectors. Since 2002, Multiplex has been owned by the south korean HiTEC group and has become one of the leading RC manufacturers in the world!
