Mike, I have a Focus AM, and I think the problem may have started after a crash, but the plane will intermittently lose control, the come back. I am wondering if the x-tail might be hurt. As you know, this is a real inexpensive radio, and I don't really want to spend more on shipping and repair than it is worth. I was wondering if I should just buy a new x-tail and try it. I have only had this about 3 years, and broke it after about a year, and since then bought a Flash 4, and SEVERAL receivers (the best thing I ever did!) So, with several planes flying with one radio, this thing is not really needed, but I thought it might be good for a park flyer/sailplane....Thanks.
