Buckle in! These unique motion simulators are capable of exposing the rider to an unparalleled multi-sensory experience. The Monster Truck rides are a combination of unrestrained racing and real monster truck feel, providing a fun and exhilarating off-road driving experience for the whole family. Burn tread, smash bumpers and best of all, feel the acceleration and terrain in your vehicle as you perform some wild stunts and try to avoid crashing. You'll feel the ground beneath you and every shake, shutter, climb and rollover like you've never imagined. The ride, featuring EnTCo's X-Vector Motion Base and high-end graphics systems, will enable two riders to race and participate in a virtual Monster Truck competition. The X-Vector features 360 degrees of continuous rotation on the pitch and roll axis and state-of-the-art sound system, providing an exhilarating multi-sensory experience. No other entertainment ride can provide the level of interaction and media quality that EnTCo delivers with the X-Vector.
