Product Features:1. Ultra-realistic craftsmanship, scaled-down replica of the actual aircraft with authentic design. Opening cockpit doors, instrument panel, footrests, elevator, and throttle are all proportionally scaled. Primarily constructed from alloy materials with anodized + sandblasted finish. GPS positioning + self-stabilizing air cushion integrated with the new-generation H1 PRO intelligent flight control system.2. New-generation H1 PRO intelligent flight control system: features interference-resistant CAN bus, advanced intelligent functions, supports BeiDou positioning system. Combines BeiDou/GPS multi-mode positioning technology for rapid satellite acquisition, superior signal quality, and strong anti-interference capability. Enables precise positioning/altitude hold, automatic hovering, and movement/stopping upon stick release—eliminating the need for constant manual attitude adjustments. Releasing the remote control triggers automatic body stabilization, significantly enhancing the 300C's stability.3. Ultra-realistic tri-rotor head assembly paired with DFC aileron-less structure. Low center of gravity and low drag optimize flight dynamics, deliver precise handling, ensure stable flight, and reduce damage risk through structural refinement.4. Equipped with JCZK-470L professional brushless outrunner motors delivering high efficiency, substantial power, high torque, low current consumption, and low heat generation. The 4S 2000KV 1150W high-power configuration provides abundant torque output for flight.5. The tail boom employs a 700-grade large-diameter design, encapsulating the drive belt and tail linkage for enhanced integration. This creates a cleaner, more aesthetically pleasing appearance while strengthening the tail section for superior rigidity.6. Full-metal high-voltage servos deliver rapid response, low power consumption, and high efficiency. All-alloy output gears offer exceptional hardness and wear resistance, minimizing gear backlash. This ensures precise flight control, responsive handling, and extended service life.7. Features the Haoying Platinum 60A V4 brushless ESC with robust current handling capacity. Includes multiple protection functions: input voltage anomaly protection, low battery voltage protection, and overheat protection.8. Equipped with a Gres 4000mAh 30C 4S 14.8V battery. Offers high discharge rate and extended lifespan, providing approximately 10 minutes of flight time. Under normal use, it can withstand over 500 charge cycles.9. Spring-loaded landing gear made of high-strength alloy provides excellent shock absorption and durability. It reduces landing impact vibrations, offers protection to the airframe, minimizes structural wear, and extends service life. Features realistic aircraft design with left red and right green LED navigation lights.10. Ledi T12D PRO 12-channel full-function universal transmitter with R12DSM mini receiver. Compatible with all commercial helicopters, fixed-wing aircraft, FPV drones, multirotors, and RC cars. Features an LCD display with Chinese/English menus for intuitive operation. Supports digital parameter tuning and simulator functionality with optimized stick output for precise control.11. Gesi Charger, 80W high-power fast charging. Built-in power adapter compatible with global 110-240V wide voltage input. Intelligent display with automatic power-off upon full charge. Features a backlit dot-matrix LCD screen displaying operation menus and charging status for intuitive convenience.
