I've been running a Bavarian Demon Cortex for several years now in one of my 50cc airplanes and love it! I've let a few others fly it and they've all like it as well. What I like is if you didn't tell someone it was there, they most likely wouldn't know. The way I have the gain set it just smooths the airplane out and makes it fly much bigger. I fly in the normal mode, but as a circus trick you can put it in hold and it will hover hands off. I've only done it a few times for pure entertainment.
One thing I've noticed is that I can do a better slow roll with it turned off for some reason. Since it's on a three position switch you can turn it off or switch modes whenever you like.
My favorite part of it is the crisp stop at the end of a roll. I love to make knife edge passes across the field and roll fast and hard the same direction as the rudder input. One fast roll that stops crisp right back at knife edge. It's awesome on point rolls.
One of the downfalls of a gyro, at my field anyway, is they are looked down on for a lack of a better way to put it. Some people seem to believe it's an autopilot and that the only reason you can fly like you do is that you use a gyro. And it even has the magical properties to make every other plane you fly without a gyro, fly better too!
