[Elecraft] Using a quadcopter to hang an antenna

[Michael Walker]

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.
