This time around, we take a look at my brother-in-law's growing collection of Q-steer RC cars as well as the tabletop race course he made. Q-Steer is a line of remote-controlled toy cars manufactured by Takara Tomy, based on the popular Choro-Q pullback line. First released in late 2006, Q-Steer incorporates micro infrared technology as opposed to the traditional radio control used by other micro R/C brands. It also uses the 40 mm long S-Tech chassis, which is an evolution of Tomy's Bit Char-G chassis. Much like their Choro-Q contemporaries, Q-Steer cars have a slot at the rear, where users can insert a coin to change the cars' handling characteristics, such as doing a wheelie. The slot also identifies the car model and the available frequencies. The car and the remote weigh 16 grams. Each Q-Steer car can be set to one of two IR channels, which contist of A-B and C-D bands, and up to four cars can race simultaneously. The controller is white with grey buttons and features
