[Elecraft] Using a quadcopter to hang an antenna

[Bill Johnson]

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.

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!!
