Hi all i only just bought a solo and am fairly new to drones in general, but down near where i live there is a big sinkhole in Braidwood NSW Australia, and i have a vision to fly a drone into it at some stage, it is fairly thick bush so im not sure what kind of gps i would get, plus the sinkhole is obviously below the level i will launch it from. Does anyone have similar experience and how could i get this done? im nowhere near good enough at this stage, i guess maybe i will try it when my solo is bruised and battered and im due for an upgrade.
