I had a tower trainer that I took the dihedral out the wing. I really liked the way it flew and the nimbleness of the trainer. I have flown a number of planes but I bought the trainer just for fun and in case some friends wanted to learn. I took it out this morning and started doing some basics like rolls and loops and stuff. Then I started showing off for my friend who purchased an Avistar but has yet to fly it. After some full speed manuevers the left side of the wing decided to go off and do its own thing. Here is the remains. The other half of the wing is about 200 feet away.
