Use the Cap 2x, or the 3D Ultimate PERSO. They both t-roll extremely easy. Although I did learn to do it in the real world before I bought the sim. It will take some practice, get em' vertical and then practice keeping it vertical. It will roll on it's own once vertical. Use trim if you have to to keep it from falling on it's back, once you get it down you can start moving the trim lever back into the original position and practise doing it from there. Good luck, and don't give up. It's so much fun.
