Using your iFlight BOB57 O3 Cinematic 6S HD BNF Drone is easy. First, make sure to charge the 3000mAh 6S battery fully. Then, bind the drone to your controller. When flying, keep in mind the max wind speed resistance of level 7 and the operating temperature range of -10° to 40° C. For video transmission, connect it to your DJI goggles as per the latency specifications. When it comes to maintenance, regularly check the propellers for any signs of damage and clean the gladiator shell to keep it protected from dust and water droplets. Also, make sure the ESC's built - in spike absorber is working properly. After each flight, discharge the battery safely and store it in a cool, dry place.
