A flyin' can o' spray paint!  Or at least that's t' intent - this is still a work-in-progress.  It turns out that BT-80 tubin' is almost exactly t' same diameter as a can o' spray paint, me bucko, and t' cap that Rustoleum uses fits well onto a BT-80 tube coupler.  What's more is that t' 2X-line use a vinyl wrap around t' can, me hearties, which is easily peeled off and reattached t' t' tubing.  T' rest is sort o' self-explanatory.  T' first flight was a bit squirrely, but t' second was better after revision t' CG location.  This may have t' be restricted t' calm winds.
