Using these T - Motor T76s propellers is easy. First, make sure your cinewhoop is turned off. Then, carefully install the CW and CCW propellers according to the markings on your drone. When choosing a propeller, pick the right color to match your style. During use, avoid flying in extremely harsh conditions like strong winds or heavy rain. If you notice any signs of damage such as cracks or chips, stop using the propeller immediately. To maintain your propellers, clean them regularly with a soft cloth. Store them in a dry and safe place when not in use. This will keep them in good shape and ensure long - lasting performance.
