Your ideal Rotational Drive Solution up to FFS Level D.



The BRUNNER CLS-P Direct Drive Solution meets the highest demands of professional flight simulation. As an element of our Control Loading System portfolio we have developed a very compact and powerful Direct Drive Rotational Solution which is able to meet the high requirements of FFS Level D Simulators, but also perfectly enable smaller scale training devices like FTDs and FNPTs.

The high dynamic direct drive brushless AC Servo motor has 20 Bit resolution per rotation and offers a very smooth response with highest force in a compact design.

The BRUNNER Direct Drive Solution is supporting single as well as dual pilot applications. A unique real-time synchronization logic enables unmatched and automatic pilot/co- pilot take-over functionality.
Targeting professional applications where type specific interfaces are required, the Direct Drive Solutions comes without any linkage but is prepared for easy mounting and connection of user specific mechanics.

Additionally to the internal Force Measurement, an external Force Sensor can be connected directly via the CAN Interface.

Enabled by our CLS2Sim software-environment, the Direct Drive Solution communicates easily with commercially available simulation software such as X-Plane, M-FSX, and Prepar3D®. Any third party flight simulation solution connects via a  simple TCP/IP or UDP remote interface protocol.

– Operating system: Windows XP/7/8/10 needed for simulation interface software CLS2Sim

– Attention! Running X-plane (10/11) on a Linux operating system requires a separate windows installation (virtual machine or separate computer) for running CLS2sim software.
