Technical Performance

The Traxxas TRX-4 1979 Chevrolet Blazer is engineered as a dedicated trail crawler rather than a speed machine, and every technical decision reflects that focused purpose. The XL-5 HV waterproof electronic speed control manages the Titan 21T reverse rotation brushed motor, delivering smooth, controllable throttle response essential for precise technical driving over rocks and obstacles. The motor's reverse rotation is specifically calibrated for crawling characteristics — providing excellent low-speed torque control rather than top-end velocity. The transmission system features a 2-speed high/low design with 32-pitch gearing and remote shifting capability, allowing instantaneous gear changes without stopping the vehicle. The differential system uses 4-gear construction with electronic remote-locking functionality across both axles, transforming traction characteristics on demand to suit varying terrain challenges. The chassis architecture employs a proven steel ladder frame with nylon composite crossmembers, combining rigidity with targeted weight distribution. Suspension geometry is meticulously balanced with front and rear shock lengths both measuring 3.54 inches (90 mm), ensuring consistent ride characteristics and predictable handling. Wheel fitment uses 12 mm hex hubs with 1.9-inch diameter wheels shod in 4.64-inch diameter tyres (118 x 48 mm front and rear), providing excellent ground contact and traction. The overall vehicle weighs 2.84 kilograms, striking a balance between stability and agility. Ground clearance of 3.14 inches combined with impressive angles (59° approach, 59° breakover, 47° departure) means this crawler tackles terrain that would stop ordinary RC vehicles. The waterproof XL-5 HV ESC accepts a wide variety of battery configurations including 4–7 cell NiMH batteries or 2S–3S LiPo batteries, giving you flexibility in power source selection depending on desired performance characteristics. The TQi 2.4 GHz radio system operates interference-free on a frequency band congested with many RC hobbyists, yet the system maintains reliable communication range through its advanced spread-spectrum technology. The 2075X metal gear servo ensures steering remains responsive and reliable throughout extended trail sessions, whilst the electronic hill hold brake prevents unwanted roll-back on steep terrain. This is a properly engineered trail tool, not a rushed compromise — every specification contributes to genuine off-road crawling performance.
