This wing started out as a set of cores cut in readiness for a powered glider. After a bagging disaster they languished unused for a few years.
I eventually threw them together as a rough and ready slope model. From the get go the wing flew really well in light to moderate conditions (4 to 20mph), and after a few flights I added pitch neutral flaps which were a complete sucess. A solid and stable flyer, but no aerobatics please (other than loops and stall turns).
below is a rather long, unedited movie of the wing in very light conditions.
