JetCat SPT-H

Are deployed in the helicopter area. An ECU software specially developed for this application allows the free programming of up to three main rotor speeds, which can then be switched on the transmitter side by means of a 3-step switch. The electronic control of both shafts ensures that the rotor speed is kept constant even during load changes.
