Using the Tinyhawk III PLUS Spare Parts Pack B is easy. First, carefully install the Runcam Nano 6 Analog Camera on your drone. Make sure it's firmly attached so it won't move during flight. Then, connect the 32Bit 400mw VTX to the appropriate ports on the drone. When you're ready to fly, turn on your FPV goggles and the drone, and you should get a clear signal. For maintenance, after each flight, check the camera for any dirt or scratches. Clean it gently with a soft cloth. Keep the VTX in a dry place and check the connections regularly to ensure they're tight. Remember to store the spare parts in a safe and dry location when not in use.
