I have mastered my trainer and now have an ultra stick 40. In no way is that a trainer. I had a sensitive trainer, and this thing will roll with a tap of the stick, Also, trainers tend to survive crashes, rough landings and the general abuse they get from first time fliers. While the plane isn't weak it cannot compair to a sturdy bird or duraplane (what i learned on, and it taught me well, and the crashes i gave it would have destroyed any other plane and ended my modelling fun.) I don't care what other people say about those trainers there great. The ultra stick is a great second plane once you can do basic aerobatics and have had at least 20 flights without incident with your trainer, your good to go. But once you can fly, Ultra stick rules.
