Alrighty, as far as stunts go I'd check this out,
http://www.blaineaustin.com/3d_tips.htm it gives you a basic idea of what needs to happen, you'll have to try it over and over again to get it to work out alright but it's a start. If you're having trouble actually flying I'm guessing it's because it's quite a bit more touchy than your slow stick, just remember to go real light on the controller, you don't have to go full left to make a slight bank roll, just a little touch, my reccomendation would to be to touch the sticks as little as you can to keep from over doing it. Another thing, if your having trouble taking off, and your trying a ROG (roll on ground) take off, that's alot harder than a hand launch. I'm not sure about the best way to launch that particular plane, but all if mine you grab by the canopy, and give it and easy underhanded toss up at about a 30 degree angle with full throttle. I hope that helps get you started, if your having specific problems go ahead and post them, I'll see if I can help.
