Crawler Crane Building Blocks Set,RC Remote Control Crane Construction Vehicles Toy ,1322 PCS Engineering Truck

【Realistic Remote Control Crawler Crane Building Set】Crawler Crane Building Blocks precision replica crawler crane operation scenarios, supporting boom amplitude + 360° body rotation + hook lifting, and switching action mode through transfer box. The tracked chassis realizes front and rear movement and in-site steering, and is equipped with a simulated joystick design to deeply restore the heavy machinery operation process. Finished size: 19.96x2.56x20.98 inch, 1322 PCS 【Dual Support】 This crane building block model also supports Bluetooth remote control of mobile phone APP, which can accurately adjust the hook speed and the angle of the boom, and the remote control headlights enhance the immersion of night operation. The quick-removal battery design is ready to use 【STEM Education】 This crane construction set explores the principles of hydraulic transmission, center of gravity balance and gear linkage by building 1,322 components, and the movable structure accounts for more than 38% (boom/hook/rotary mechanism). 【Great Building Experience】This crane toy is made of high-quality and environmentally friendly ABS materials to ensure accurate color matching and a solid structure. Each piece is polished with exquisite finish, smooth feel and has a good fit. The package contains comprehensive and precise paper assembly instructions, which are simple and easy to understand
