I've been flying my 4 Star 60 ARF for about 5 weeks now. It trully will make you a better pilot. I concur with the few problems the other guys ran across. It does have a weak main landing gear. I'm going to try a Hanger Nine heavy duty .60 size and see if it is any better. I was told to get a Kletts fiberglass, but can't seem ti find a .60 size anywhere. Defineately replace the stock tail wheel bracket with a sullivan! Other than that, a great plane. I put an O.S. .61 FX on mine, and it will run for over twenty minutes, with fuel to spare! Another great plane I recently put together and flew was a Graupner Super Air. Unfortunately, due to a radio problem, it augered. I will be replacing it, however, as it was an awesome .40 size plane!
