A friend of mine had his little drone land (crash) on the top of a neighbor's roof. I tried to retreve it with my Mavic Pro Platinum. I tied some fishline to the bottom rear support bracket of my drone and ran it forward underneath to in front of the two front arms close to the body and over the front of the body taping it there. From the middle of the drone underbelly I dropped a line about a meter (3 ft) downfrom the afore mentioned lines to a sturdy wire that had been made into a hook. It flew well except that the line was too thin and the down draft from the rotors caused it to swing quite a bit. On the second try to capture his drone the monofiliment lne got caught in one roter and down she went, but it's ok except for having to replace a blade set. Next time, if there is a next time I'm going to put some weight just above the hook to keep it more stable when flying. Does anyone know of a setup that would work better? Perhaps an addition that would better secure the line on the drone?
