LOCKING DIFFERENTIALS. Just as with your full-sized rig, the 1:10-scale Bronco’s front and rear differentials can be locked and unlocked, according to the terrain you drive it on. Leave them unlocked when the going is smooth, and lock them down when tackling tricky, technical trails.

TRANSMISSION. Moving from one crawling section to another? Select “high gear” to get there quickly. Once you’re ready to crawl, hit the rocker switch on your transmitter to engage “low gear” for extra torque and power to crawl the rocks.

PORTAL AXLES. To provide additional ground clearance, the TRX-4 is equipped with portal axles that lift the differential “pumpkin” up high. The axles not only give you better ground clearance over trail obstacles, they also improve axle geometry that reduces strain on the driveshafts.
