That's true Dan. But 1/4" rubber is often not available anymore and Supersport is way stretchier than the old Black FAI rubber. So a 6" loop is about the most that most people with normal length arms can stretch comfortably.

Two 1/8" loops are allowed now.
The rubber limit is there to limit the plane.

I, too, use double-loops of 1/8" rubber. My technique is to tie an overhand knot, for securing the loops together, and a lark's-head knot for securing the assembled loops to the launch stick.

I'm currently using old Estes rubber, but will switch to FAI tan when the old stuff breaks. I may be more thrifty than most!  Grin
