If it's that dangerous, I would be standing at the bottom - or maybe investing in a drone parachute to get it down.
"The Bottom" is a bank to bank creek. And I will be first in line to get the WATERPROOF Evo. If I could land it on the water and not risk destroying it- that would simplify everything. Attached is a photo of the location I was in when I figured I needed some other sort of landing/take off system. Kinda steep.
