Sobre este artículo

• Powerful & Efficient Drivetrain: Features a 4282-2600KV Sensorless Brushless Motor (high-speed digital sensor, plug-and-play, no calibration needed) paired with a 140A FOC Vector Control ESC supporting 2-4S LiPo batteries. FOC technology saves 5%-20% energy compared to traditional square wave ESCs, significantly extending runtime for extended crawling adventures
• Smart Multi-Mode Switching: Instantly toggle between 4WD/2WD (FWD/RWD) to conquer different obstacles. Switch High/Low Gears On-The-Fly – high speed for flat terrain, low gear for maximum torque on rough trails. Independently lock/unlock Front/Rear Differentials – unlock for agile steering & tighter turns, lock for superior traction and obstacle clearance
• Extreme Durability & Chassis: Full CNC Chromium Steel Gears (1.0M motor pinion/spur, 0.8M transmission gears) ensure exceptional strength. Thickened 8mm Stainless Steel Suspension Links and Oversized Front/Rear Axles build a rugged chassis. Twin Friction Plate Slipper Clutch protects gears and motor under extreme conditions
• Superior Climbing Stability: Forward-Located Gearbox lowers the center of gravity, minimizes torque twist, and enhances hill-climbing stability. 3-Link Panhard Steering System reduces body roll for smoother handling on bumps and straighter tracking. 120mm Full Metal Hydraulic Shocks (37mm max travel) provide plush damping on rough surfaces
• Professional Control Experience: Includes a 2.4GHz 10-Channel Transmitter with a 350m (1148ft) control range. A powerful 45kg Waterproof Steering Servo delivers strong steering force, supported by 4x 25g Servos for precise control of gear shifts, diff locks, and drive modes
• Optimized Rock Crawler Design: Engineered for peak performance: Full-Time 4WD, Differential Lock System, Long-Travel Suspension, Low CG Layout, and Robust Construction empower you to easily conquer diverse terrain and challenging obstacles
