The Buttkicker Simulation Kit has arrived. After being sold out for years it is finally available again. It’s a fine piece of hardware. Connecting is easy. I’ve screwed the Transducer under the original B737 seat and it makes a difference during flight.
What is needed now would be to add low frequency vibrations to individual flight systems such as landing gear, flaps or for environmental influences such as turbulence or ground contact. The low frequency vibrations are only partly realistic through the original X-Plane sounds.
