More information

The system is equipped with a rubber "wide belt" and a vertical support/pylon that allows the scale model to be supported, up to 40% model scale. At the lower end of the pylon, which can be adjusted vertically, and inside the model itself, there is a 7-component aerodynamic balance scale and a trim variator to adjust the pitching angle. The rotating wheels can be connected directly to the model or supported externally by instrumented arms.
