II. Product Performance Advantages

• Light configuration: Model A has no lights. Model B has a headlight.
• Chassis structure: The chassis is made of 2.5MM thick aluminum alloy, which is more durable than plastic materials. It provides more stable driving and is not easy to overturn. With hardcore metal reinforcement, the structure is stable and can withstand various impacts when the vehicle climbs.
• Power system:
  • The high-efficiency power motor adopts zinc alloy gears, which have higher strength and wear resistance than general plastic gears, and the durability is significantly improved. Equipped with a high-operating motor to supply excellent power. The 550 motor can be replaced without damage, and the 390 strong magnet motor is upgraded.
  • Real-time four-wheel drive power. The metal front and rear differentials cooperate with the metal drive shaft. The four-wheel drive linkage has strong power, making turns more natural and smooth.
  • The vehicle electronic speed controller is independently developed. The 35A 2S electronic speed controller has PX4 level splash-proof function. It integrates receiving and control. It has functions such as low voltage power-off, temperature control protection, and prevention of motor jamming. The waterproof coefficient is as high as IPX4.
• Control components: 17G 5-wire servo, accurate and flexible control.
• Shock absorption system: The oil-pressure serrated shock absorber has a maximum diameter of 17MM and a fast rebound speed. It increases tire grip. It effectively reduces vibrations during high-speed driving and makes driving stable. When encountering obstacles, it can effectively reduce impact. The hardness can be adjusted by rotation.
• Tire characteristics: Off-road large tires with unique treads have stronger grip and are suitable for various road conditions.
• Remote control system: 2.4G remote control, supports multiple players to play. Full proportional acceleration and accurate control of the steering angle. It can be controlled freely from low speed to high speed through the throttle trigger, just like the accelerator pedal of a real car.
