Using the TBS Folding Prop Set is easy. First, make sure your motor has a 6mm reverse - mount shaft. Then, attach the TBS propeller mount to the motor shaft using the provided screws and bolts. Next, install the Aeronaut CAM 10x6 Folding Prop onto the mount and secure it with the Delrin Prop Stop. When flying, the prop will spin as normal. When you stop the motor, it will fold back, allowing for smooth gliding. When landing, the folding feature protects the prop from damage. As for maintenance, regularly check the screws and bolts to ensure they are tight. Clean the propellers gently with a soft cloth to remove any dirt or debris. Avoid using harsh chemicals as they may damage the carbon - fiber material. If you notice any signs of wear or damage, replace the propellers or other parts as needed.
