[Elecraft] Using a quadcopter to hang an antenna

[Bill Johnson]

I don't have photos but my launcher is similar but the sprinkler valve is on the end and the "shooting" tube is on the end... not so compact. The overall length is 40" + and it is easy to aim.  The issue is how much air to use.  My air cavity is much shorter and I can do 70Lbs. with a bicycle pump.  I can do 90+ lbs. and agree with the spider wire.  

73,

I built my own and chose the spiderwire fishing line.  Works great.  The fishing line is hard as heck to see  but super strong.  Goes over 100ft trees with no effort.
