Using your Emax Babyhawk II HD is a breeze. First, make sure you've chosen the right receiver as per your preference. Then, power on the drone and your controller, sync them up. When flying, start in an open area away from people and obstacles. Keep in mind that this drone is very responsive, so gentle movements on the controller will give you better control. For maintenance, after each flight, check the props for any signs of damage and replace them if needed. Clean the camera lens to ensure clear vision. Store the drone in a cool, dry place. Avoid flying in extreme weather conditions like heavy rain or strong winds. If you're not using the drone for a long time, charge the battery to around 50% and store it separately.
