Here are a few more images of my motorized and remote controlled 8053 Lego Technic Mobile Crane. You can watch the video here to see the lego crane controlled by an RC Radio.

Image below shows the front driver cabin. The the left is the circuit board for the Flashing Hazard and Warning Lights and in the middle is the Futaba Receiver for the drive, steering and crane turning control.

Image below shows crane operator seat with RC Servo in the background to control the crane arm up and down and hook up and down gears.

Image below shows 2 RC Servos for crane arm, extension and hook control, older Lego Mindstorm gear motor to power the crane unit, old Lego light and sound lights (red) to indicate power to the motor, as well as the 2nd Receiver, Battery pack (empty) and ESC (Electronic Speed Controller) for complete control via Radio over the Lego Mindstorms motor. The very rear show a yellow LED that will flash while operating the crane.
