Hi there I'm new to drones and to this forum so nice to meet you! I've bought a used mavic pro with extras(fly more combo) for £360/$486.85 still haven't received it, it's with Royal mail but just want to know what the first thing to do in order to set up the mavic pro and is there any hacks I can do in order to get the best flying advice and also did I get ripped off or a very good bargain.
