RE: Tri Gear versus Tail Dragger
It has always been my experience that tricycle geared planes are easier to take off but more difficult to land and taildraggers are more difficult to take off bet easier to land. Choose you option.
If you wanted a trainer plane with ailerons then you probably should not have bought that one. I would recommend just learning to fly that plane the way it is and save any mods and ailerons for the next plane.
