The Traxxas TRX-4 Defender Limited Edition in tan is packed full of features right out of the box. It features remote differential locks, remote high and low gearing selectable via a switch, portal axles, inner fenders, waterproof electronics, a metal geared high-torque steering servo, and aluminium shocks. The TRX-4 uses three fully-waterproof micro servos to actuate the front and rear differentials as well as the high/low range selection on the transmission. Sleeved micro cables eliminate complicated linkages that would otherwise limit suspension articulation.

Top speed: 18 kph. Skill level: Intermediate.

T-Lock remote locking differentials

Portal axle front assembly

High/Low transmission assembly

The Traxxas TRX-4 features a high-speed gear to get to your next crawling challenge quickly, then flick the rocker switch to engage low range for exceptional torque.

Micro cable differential actuators

TRX-4 uses three fully-waterproof micro servos with sleeved micro cables to actuate the front and rear differentials, eliminating complicated linkages that would limit suspension articulation.
