...and that's the difficulty. As near as I can tell, terms like 2-wrap, 3-wrap, and 4-wrap are used by experienced flyers.
I looked Kitty Hawk and couldn't find parts. I really hate their site. I looked on GWTW and found parts, but when it comes to spars, I'm lost. Same goes for Into The Wind. Lots of rods, but I don't know what I should be looking for.
