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.
Mini 4WD can be purchased in hobby stores or online. Few companies do not include an electric motor required for the car to function. The car can be powered by AA batteries, including rechargeable batteries. Its body frame has a frontal bumper extending sideways to hold the rollers for the tracks. An optional plastic bumper for the rollers comes for the rear of the body. For 4WD (four-wheel drive), traditional models conjoin the front and back wheels with an aluminum rod; as for the Mini 4WD PRO series, the motor located in the center of the body powers both the front and back wheels. The assembly package should come with a grease for the gears. Although the internal designs for the Mini 4WD's remain the same for the models of the same series, a plastic cover, which attaches with a lock at the back of the car, distinguishes one model from another; additionally, the wings on the plastic covers allow for improved down force and stability.
There are three specifications that characterize all motors: RPM, torque, and power-consumption. RPM is the speed the motor provides, and the torque its strength. Higher the RPM means higher maximum speed and acceleration rate; Higher torque allows the car to better withstand the difficulties of climbing slope or running through turns.
The mini car should have at least two sets of gears in the assembly package for the motor to spin on. Different types of gears have different ratios of rotation of the motor and the wheel, and they include "3.5:1", "4:1", "4.2:1", "5:1", and "6.4:1". Higher the ratio, better the acceleration rate and torque; lower the ratio, better the maximum speed.
There are four types of different wheels: normal plastic, one-way, aluminum, and lock-nut. Normal plastic wheels are fine, but they are not adequate for really fast cars. They become loose after disconnecting them from the axle several times. Additionally, they create drag when the car going through turns as the axle locks the two wheels at same speed, since the outer wheel must cover more distance than the inner wheel (relatively to the turn of the course). One-way wheels allow either side to roll faster than the other when turning, and minimize the speed loss in turns. Aluminum wheels are very light, sturdy, and best for speed. Some aluminum wheels have preventive measures against loosening with the axle. However, lock-nut wheels are the best in preventing the cars from losing the wheels during a run.
There are four types of tires: rubber, sponge, reston, and semi-pneumatic.. Rubber tires come as standard with the Mini 4WD, and, although it has good grip, it is heavy and is susceptible to slipping during rains. The alternate solution to the rubber tire are the reston or sponge tires, which are very light, have good grip, and are better suited for rainy days. Yet, these get dirty easily, and they tend to exhaust the motor.
