I wanted to upgrade the X truck with smaller, yet more capable power functions. To do this the axles and the body was rebuilt to make the new offroader shorter, lighter and more maneuverable. Now each axle has its own steering motor, which works independently. This allows the truck to drive in almost every direction, EVEN SIDEWAYS. Also the planetary gear train inside the turntables was found to be more efficient than a single tooth gear powering the turntable from inside. Suspesnion was soften up to allow better ariculation and the weight was lowered due usage of rechargable battery boxes (yes two of them). This in combination with IMO the best official offrading wheels reulsted in THE BEAST.

No terrain is too tough for this offroader, thanks to its total gear ratio of 1:6,25 from the XL motors.

I am quite impressed with this truck’s power agility and overall performance. It may be one of my slowerer and oddest trucks, but it sure can crawl!
