RE: Parkzone f4U Corsair Rtf
I bought the PNP version since I already had a DX7 for my helicopters. The Corsair is my first and only airplane so I'm not well versed in airplanes but I can tell you that it flys very well with almost no adjustments out of the box. I would bend the landing gears slightly forward closer to the leading edge of the wing to help it from going nose over on landings. I heard from others that the wing servos may stick on you. I was flying with another person who's servo did in fact stick. I for one have not (so far) had that problem. I don't like the stock wheels (small and mushy). So I replaced the mains with lite weight 2 1/2" wheels. I also replaced the tail wheel but I don't recall what size.
I think you are making an excellent choice in this airplane. Welcome and have fun.
