Look at the release mechanism in this video:

I did this years ago and even had it published in QST. It was at least 4-5
years ago.
It was a basic Quad copter, a simple Wii flight controller and a dedicated
servo that pulled a pin out of a block to release the weight.
It worked very well. I should get the pick back on my QRZ page.
I bet I had less than $100 invested.

My problem when I miss is getting the weight to go back up without
tangling or coming right back at me. I made a Pipe cannon using bicycle
pump compressed air with a sprinkler valve opening with two 9v batts. The
same issue watch out for the weight. I use a pair of caps on smaller pipe,
but that can still be an issue. Now to find a use quad copter.

Subject: Re: [Elecraft] Using a quadcopter to hang an antenna
Interesting.
I have a 5 servo 8ft Helicopter, been flying them for years, but I've
always used an old 12ft fishing beach caster with 30lb line and 5oz fishing
weight..
I can zip it over a 100ft tree, tie on a light line, reel the fishing line
back in then you can haul up the dipole end.
Takes a few minutes to set a full 160m dipole between 2 suitable trees for
Field day.
Look out for one at your next boot / flea market sale!!

A few weeks ago several folks here were discussing the hanging of an
antenna line with a quadcopter and were wondering what's available to
allow a quad to drop a line over a tall tree or other structure.

I just finished putting my 80m dipole up at the 90-foot level and took
a few photos of what I use to do it. The key to the whole thing is the
payload release device since a quad cannot descend with the line still
attached.
