I had a Goldberg Wildstick 40 back several years ago. It too had a "thick" wing with a short moment between the wing and the horizontal stab.

This thing had flaps, ailerons, elevator, rudder.. the whole works. I had an OS 50 SX that was sitting around gathering dust, so it went on the Wildstick.

It was a blast to fly.. but when coming in for a landing, if I wasn't careful, as soon as I would pull elevator to flare, well, up it would go.. not just bumping up, but climbing for 20 - 30 feet, so I would add power and go around. I finally learned how to bring it in without the ballooning. The flaps were useful only for some pretty wierd "aerobatics" (full flaps and full up elevator and it would loop in pretty much it's own length).

It was indeed wild!!

If the Twist is anything like it, well, it ought to be fun to fly.
