How many of us have lost a line reel clip at the field?
Here's MY answer to that.....
Prototype of my GPS locating line reel clip.  Shows promise. 3D printed of course!
The phone app is the hard part.
I envision different colors for different line diameters?
Green color for the foolish too.

One set of lines and one handle for each airplane. Crist may have a dozen airplanes😊.

As far as power Igor, I know Dave is working on a dark matter energy extraction device that weighs -3g.
