Crawler-type stone-ups remote controlling assembling kits (hand-assembled electronic motor car)
145mm (length), 105mm (width), 70mm (height). This is a strongly operational remote controlling assembling model that is composed of the remote controller, the motor, the power supply, the traveling gear, and the frame. After the assembling is completed, the model can travel across the obstacles set by the book, or across seven standing used batteries arranged in a random order under remote control. By assembling and operating this model, students can not only get some knowledge about the electronic circuit, but also achieve better coordination of the brain and hands.
