From an article by inventor Mr. Michael Moran (Peak of Flight Newsletter#531)

It’s as simple as a tube (plastic straw) around a mounted dowel and string (Kevlar in this case) and polyester fabric. Had everything laying around; dollhouse shop supplies, fishing tackle, Christmas ribbons, and miscellaneous eye hooks, etc.

Here’s the first incantation. flimsy plastic bulkheads for testing

Here it is with balsa bulkheads and all rolled up, just as the article describes: 14″ of fabric, then 50″ of streamer. Fits nicely in the QCC Explorer. Cant wait to test it (maybe in a coupe of weeks)
