The Kwatz was a free plan in one of the model magazines a couple of years ago. So Simon built one...to learn to power-fly with. He had done sopme gliding previously, but for his venture into the world of model planes with engines he couldn't have picked a more unsuitable plane. Basically a Fun Fly without a Tailplane, it at first was a struggle to fly...a dodgy rearwartd CG, MASSIVE control throws, and a piddly little engine. Oh Dear.
I eventually plucked up courage to have a look at the model and give it the once over, bung some lead in the front, reduce the movements, and tune the engine in to get as much power as possible. As it was, nearly everyine used to cower behind the benches on the site whenever simon flew. After all this set up work, I had to give it a try, then give Simon a few pointers as what and what not to do. I have never flown a plane so unpredictable. When doing looping manouvres, after letting go of te controls it would carry on looping as if the wing was just just tumbling end over end. Very strange. But with minimal movements it became more reasonable to fly, and became more fun than terror.
Flat spins are a doddle, and it will even prophang quite well. Thomas reckons it prophangs better / more easily than a Cougar...I don't think so, although it will do it better in a breeze due to the extra weight. Also, having such a fat wing does not help the glide, if you get a deadstick, the chances are that it will pretty much underneath the spot where it is when the engine quits. Simon has built a novel model with this Kwatz2, and I always look forward to giving it some stick when he lets me have a go.
