Hey Bob, it is good to hear from you again. My Hawk has had it's third rebuild and is still going strong, hope yours is too. Last summer I has a chance to watch a friend fly the Motion RC OV-10 Bronco in a scale contest. The plane is amazing. I didn't get a chance to fly it. The plane managed to fly the required 10 maneuvers and at best that takes about six minutes, so it has the flying time for a reasonable flight. Although the wingspan is 10 inches smaller watching it didn't appear to be smaller than mine.
Don't worry about the FAA, buy the airplane and enjoy it.
