After installing the propeller guard on your Mini 4 Pro, obstacle avoidance and autonomous functions will be disabled. When the drone detects obstacles, it will not automatically reroute or brake, requiring manual control during flight. Do not use the Intelligent Flight Battery Plus with the Mini 4 Pro when the propeller guards are installed. The additional weight may exceed the drone's capacity, which could compromise flight safety and performance. Package includes one set of propeller guards designed specifically for the Mini 4 Pro. The guards are securely attached to prevent interference with propeller operation and ensure reliable protection during use. Comprehensive protection: fully encloses the drone's propellers, shielding them from impact damage. Ideal for indoor and outdoor flights, particularly in environments with obstacles. Due to manufacturing variations, there may be slight differences in product appearance and labeling, which do not affect functionality. Color: Black. Material: ABS. Package contents: 1 x propeller guard kit. Only the items listed are included; other accessories are not included. Note: Lighting conditions and display settings may cause slight color variations between the image and the actual product. Measurement tolerance: +/- 1-3 cm.
