the Fling is sweet just got done building one and tossing it around inside and outside. if thrown in the wind just right, she'll cruise around for a short while, hard toss results in a loop. i added a little something to mine just to try. i poked a hole in the bottom of the lower wing and inserted an inch long peice of CF through it, then i glued the CF rod into the upper wing (canard?). added a little peice of heatshrink tubing to the CF and now i can adjust the angle of the little upper wing. it can make for big changes in flight. the thumb tack was the only thing i had within arms reach, but it seems to work well.

i didnt check to see how long it took to build it, but it wasnt very long, used two foam dinner plates and foam safe CA for contruction. these could work really well for AA or other equipment, quite stable for a flying wing!
