Features
1. Body Construction: The main body predominantly uses CNC and stainless steel sheet metal processing, with certain few decorative parts using ABS molds.
2. Upgradability: This model offers various upgrade options such as GPS, rubber track pads, and multiple attachments such as grippers, rippers, etc. to enhance playability.
3. Innovative Hydraulic Proportional Valve: First to use newly developed 1/14 mechanical model proportional hydraulic directional valve, with precision reaching the micron level, which makes the hydraulic functions of the excavator much more delicate, smooth and realistic.
4. Integrated Hydraulic Pump Station: The hydraulic pump station integrates an oil tank, pressure regulator, pressure gauge, oil fill port, balance valve, oil discharge port, oil level indicator, bringing incomparable stability, and thus, doesn??¡ê¡èt leak oil like other machines. The integrated hydraulic station block makes the appearance much neater and more convenient for subsequent maintenance.
5. Integrated Chassis: The one-piece CNC formed chassis increases body strength and looks much more realistic, two brushless motors provide stable torque output for drive.
6. Upgradable Tracks: There are four mounting holes pre-drilled on the track links to facilitate the installation of the rubber pads onto the tracks, enhancing friction while simultaneously reducing noise, allowing you to operate the excavator on smooth and delicate surfaces without leaving a scratch.
7. Swivel Hydraulic Slip Ring: Uses a star-shaped oil seal and flank design on the cylinder nozzle for excellent sealing performance, preventing oil leaks.
8. Optimized new Cylinder Design: Adopts a new flank design, with the sealing principle and structure of real vehicle cylinders, ensuring smooth operation.
9. CNC Stainless Steel Arms: The excavator's arm is made of stainless steel plates welded with steel sleeves, which not only enhances the overall texture and realism but also provides good strength. Multiple holes are pre-drilled allowing operators to easily modify and upgrade it themselves.
