The assembly of mini 4WD is really a form of recreation. Every time I finish assebling a mini 4WD, kooing at the reation in my hands, I can't wait to let it hit the ground!
Now let's look at some breif history of mini 4WD and some basic knowledge of it (ref. Wikipedia):
Mini 4WD was first created by the Japanese company Tamiya in 1982. Since then racing and tuning up mini 4WD cars have become a hobby for people across the world.
Other companies have ventured into the Mini 4WD market, and they include Tokyo Marui, Kyosho, Academy, Auldey, Okami, Gokey, HJH, Twinkk, and AA. Many of them introduced their own lines of mini cars, while some produce replicas of Tamiya cars, i.e. "Tamiya clones". The clones were a more affordable alternative to the more expensive Tamiyas, which gained popularity in the Philippines in the early 2000s, as well as several Asian nations.
To feed on the high popularity of the cars, Tamiya commissioned Shogakukan, a Japanese publishing company, to produce two anime TV series based on the Mini 4WD cars: Dash! Yonkuro in 1989 by Zaurus Tokuda, Bakusou Kyoudai Let's & Go in 1996, Bakusou Kyoudai Let's & Go WGP, Bakusou Kyoudai Let's & Go MAX, and finally Let's & Go!! Tamiya, The Movie.
Since 1997, mini 4WD cars have been availed in the United States. Beginning with Racing, Tamiya's different Mini 4WD series include Super, Fully Cowled, Aero, and Mighty. Tamiya used to annually hold the Great Japan Cup, but the company stopped it in 1999 to promote their new product, "Dangun Racer", begun in year 2000. The latest Tamiya Mini 4WD model is the "Mini 4WD Pro", introduced in 2005. This is the fastest Mini 4WD product available out of the box, due to its super-efficient, completely redesigned internal layouts: polycarbonate body, double-shaft motor in the center, and the batteries on either side of the motor to allow low and balanced center of gravity.
