If I decided to buy that electrastar what other types of airplanes could I fly with the Futaba radio that comes with it ? Would that radio fly say the J-3 piper cub ? And you say I could fly 6 different airplanes with that radio ? I have a large area to fly at my home as I live in the country in Washington State, thats why I would like to get a larger scale plane . I really want the J-3 cub but thats a lot of money and I could get the Electricstar for a lot less and its the same size !! I wonder what the difference would be in the way they fly ??
