This slot car race track set features multiple track configurations, including straight, S-shaped, circular, and a double-layer overpass design for varied racing experiences. The track includes an automatic lap counter to monitor race progress in real time. The 42-foot circuit is longer than standard tracks and assembles easily with a secure locking system, fitting within a 5x7-foot space. Safety latch locks and enhanced magnetic stability help keep cars on track, while replaceable bottom brushes simplify maintenance. The race cars reach speeds of 300-370 mph on the electric track, with two power options: a plug-in socket for home use and hand-crank generator remotes for portable racing. The set is constructed from durable ABS plastic and is suitable for ages 6 and up. Adult supervision is recommended for initial setup to assist with assembly and skill development. Customer support is available within 24 hours for any inquiries.
