Designed for serious off-road action, the TRX-4 is a 1/10th scale radio-controlled Land Rover Defender. The life-like detail of the model is impressive and this thing is waterproof, too. Perfect for plowing through streams and mega mud puddles. It also has an advanced 2-speed transmission, and locking front & rear differentials for climbing the steep stuff. There’s even a fully functioning spare mounted on the back.
