For DJI Mavic 4 Pro STARTRC Sled Anti-fall Anti-dirt Heightened Landing Gear Training Rack (Grey) 1. Specifically Designed for DJI Mavic 4 Pro: This foldable landing gear is tailor-made for Mavic 4 Pro. It does not block the aircrafta??s indicator lights, cooling vents, bottom sensors, or visual system. The sled-style shape helps reduce aerodynamic drag during flight, providing greater stability during takeoff and landing. 2. 30mm Height Extension: Increases the ground clearance by 30mm, reducing impact during takeoff and landing on uneven surfaces. It effectively protects the drone body, gimbal, and propellers from dirt, debris, and potential damage. 3. Durable & Lightweight: Made from high-strength plastic, the entire landing gear weighs only 40g. Its lightweight design does not burden the drones flight performance while maintaining strong load-bearing support. 4. Custom Fit with Foldable Quick-Release Design: Easy to install and remove, the landing gear stays securely attached during flight without wobbling or falling off. Battery replacement can be done quickly without removing the gear. 5. Compact and Portable: Foldable design allows for convenient storage and portability, offering extra protection for your drone wherever you go. Note: The landing gear must be installed with the drone arms unfolded. After installation, the arms cannot be folded back, and the drone may not fit into waterproof cases or all-in-one storage compartments.
