My friend Zog built one of these and hated it for some reason.  He tried to fly it to death by stuffing a C6-5 in it and flying it at B6-4 Field.  It came down without issue both times and changed his opinion about it.  Then I almost treed mine on the A8-3 flight.  I lost it in the sun and was sure it was going to wind up in the trees, but it flew along the treeline, not toward it.
