This one amazes most new people in the hobby, but every trainer on that list can do quite a bit of aerobatics. Some just have to work a bit harder, but they'll all do it. IMHO everybody needs to keep their trainers and take them back out every now and then to fly aerobatics on. I still take mine out. For me, it actually helps me to fly them on the trainer because you have to technically correct for the maneuvers to work on it. It's all pilot skill on the trainer, not a fantastic plane making up for poor technique!!!
