I was flying my trainer (Avistar) at our club field one day and the owner of the LHS came up and asked me how many rubber bands I had on the wing. I thought he was testing me since I was relatively new. I told him 10 and he asked if he could fly it. The next 5-10 mins was the best display of aerobatics I have ever seen with a trainer. At the end, he handed me the radio back and said: "See I told you that trainers can handle more than most people believe." Just make sure you have plenty of them on.
