After watching all the work on this thread, I could hardly believe my eyes when I saw those wings without their fences. I think your guardian angel must have been working overtime to blow the receiver!
At Abingdon yesterday, I spoke to no less than two former Hawk owners, whose models had turned turtle on take off. Each admitted to an absense of wing fence. Make them a bit oversize for safety.
