It was the first kit to be made available to customers and is now used all over the world. It was developed for radio control and uses model airplane servos for 360-degree horizontal rotation (pan), vertical tilt and shutter control. However, the BBKK can also be used without radio control with an interval timer called an intervalometer.Assembly can be done with simple tools within three to six hours, depending on how complex you want to make it. This system is a customizable, expandable system.
