RE: Second plane.
The Kaos is a very responsive plane will follow your stick movements closely. Thats why the Kaos isn't used as a trainer even though it is capable of very slow flight. Most 2nd/sport planes will be much faster at full throttle than any trainer and also be much more responsive. Thats why going from a trainer to a sport plane can be a shock and leave you panicking if you don't have the experience to go with a light touch on the sticks. The Kaos being a pattern plane is more responsive than most sport planes to be able to fly pattern so your buddys plane was probably setup properly. You just aren't ready for that kind of plane yet. Btw, a Decathlon is a high wing but its as responsive or more so than a Kaos so that wouldn't be a good choice right now either! [X(]
