Default RE: performance of a Kaos

yes on the UFO. It flew okay but the Curare wins hands down. Just a better balance of properties overall. Zero coupling in any axis. Hans Prettner, Hanno's father, was an excellent designer as was Wolfgang Matt.

UFO had a very large stab and you know how I feel about overstabilized pattern models. The Escape was similar if I remember right. I had actually calculated the TVC of the Curare and it was somewhere around 0.75 if I remember right. In contrast UFO had a TVC of close to 1 which is excellent for a high wing trainer but too much for an aerobat. But then again, for the maneuvers we flew back then, it did just fine most of the time.

The Curare, built wih today's knowledge and materials would be around 6 1/4 lbs, maybe lighter, and would have very equivalent wing loading as today's models. A good 60 would be great, a OS90 overkill, and a YS 90 heli engine ridiculous. Let's do it

I'll run ya a copy, NP. I am probably going to build it when my big project is out of the way. Wanna see who can build a kooler one???? (I know you'll win, but it'll make for a couple of sweet planes!)

I've just never been a Kaos fan, and I love to tease the Kaos cultists I had a few, liked them ok at the time, but it just became clear there were better planes to do what I wanted to do. So the only real reasons I can see to have one is nostalgia, and simplicity. (at this time anyway). Same with the Curare, but personally I just love that plane! Ever flown a UFO, how do they compare?

I've got original Mach one plans too, but the straight LE freaks me out......
