RE: GP Shoestring
It will be several months before its maiden flight. -18F a day ago. Also a little reluctant to fly it as I have only 4 Gal of fuel under my belt, mostly with a Nexstar and GP Spacewalker, and a little with a twin star. I have a GP supersportster in a box that will get put together in the next few weeks. Once the season comes I will work a lot with that before I attempt the Shoestring.
Going to run a 13x6 with 10% when it is time.
