- TRX-4® Unassembled Kit: 4WD Chassis with TQi™ Traxxas Link™ Enabled 2.4GHz Radio System
This TRX-4 Unassembled Kit offers a versatile 4WD chassis with a TQi Traxxas Link Enabled 2.4GHz Radio System, providing enthusiasts with the thrill of building their own RC vehicle. The kit includes an easy-to-follow full-color assembly manual with true-to-scale part illustrations and helpful assembly tips. Notably, the body is sold separately. The kit features a Trail-tuned XL-5 HV Waterproof Electronic Speed Control with five drive profiles, along with a powerful Titan 550 Motor and Portal Axles for increased ground clearance and improved axle geometry. The transmission offers two-speed high/low range with remote shifting, while the TQi 2.4GHz Radio System ensures precise control with adjustable settings. The rigid steel frame allows for multiple wheelbase positions and adjustable shock tower positions, while the innovative battery compartment provides quick and easy battery access. The drivetrain features full-time shaft-driven 4-wheel drive, tough stub axles, and steel CV driveshafts. The steering system includes a chassis-mounted metal gear digital servo for superior control, and the suspension setup includes pre-assembled aluminum GTS Shocks for smooth damping on tough trails. The kit comes with 1.9″ Canyon Trail tires mounted on tough black scale wheels, offering excellent performance and durability. Additionally, the TRX-4 Unassembled Kit includes sealed ball bearings and requires a battery and charger (sold separately) for operation
