Using these DalProp T5143.5 freestyle propellers is straightforward. First, make sure your device is turned off before installing the props. Align the hub of the propeller with the motor shaft and secure it tightly. When flying, keep in mind that these props are designed for a smooth experience, so fly in open areas away from obstacles. For maintenance, after each flight, check the props for any signs of damage such as cracks or chips. If you notice any issues, replace the prop immediately. Clean the props regularly with a soft cloth to remove dirt and debris. Store them in a safe place to prevent any accidental damage.
