So I've launched it twice and am getting a feel for it, but I am curious about the internal trim strap (string) that comes out by the spar. I assume it is like the strap inside the charger I, but haven't really fiddled with it yet.

launching in super light winds is annoying, but doable

I've pulled the string about 4" on each side with mine. Agreed, light wind launching such a high AR is a pain but it's great once you get it in the air.
