Traxxas makes some of the coolest and most accurately detailed radio-controlled models you’ll find. One of the latest creations is the TRX-4, equipped with tracks instead of tires. As a result, with added traction and ground clearance, these 1/10-scale 4×4 vehicles can travel over sand, rocks, mud and water just as competently as a full-size version. The complete package with hand-held controller sells for $550, which includes a complete set of wheels and tires that you can swap out in place of the tracks.
