white remote-controlled truck

This is my new white truck. It has four motors and four leds and it is also remote-controlled.
It weighs 1,7kg and is 45cm long.You see the controller, too. I need about twelve hours to build it. One motor is for the steering, one for lock/unlock the trailer coupling, two for driving.

This is the better controller. It has a real steering wheel.

This is the truck from the back.
