Why did I buy a DJI F450 Quadcopter?

So apparently I jumped head first into the quadcopter world by building this weapon. It’s not a drone, if anything it’s a UAS (Unmanned Aircraft System) but that sounds bollocks too.  It’s a quadcopter, it’s got four rotors and is piloted by me, with a transmitter and sometimes I wear video goggles so I can fly it in first person view (FPV) depending on the situation. So the finished product, a DJI  (yes they make Phantoms) F450 on my walking backpack with RayBans for scale.
