Incidentally if you bought it a year ago and haven't looked at it since I would strongly suggest that for each battery you fly it through several flights from fully charged to 20% in a hover at the minimum height over a sofa cushion or pillow etc. at the launch point.
This is just incase the battery or batteries decide to die suddenly.
If low and at the launch point, over something soft, you are unlikely to do much damage if the drone falls.
It will be boring but better that than have the battery die at a height of 200ft and half a mile away,
