RE: Is it hard to fly a Cub?
The only thing I'll add to the above is after the tail has lifted - WAIT - Let it stay on the ground and build up some more speed. Then gently lift off. If you try to lift off just when the tail breaks gound, I'll guarantee a ground loop! Cubs sometimes have a reputation of being hard to take off. Let the tail come up - build up some more ground speed and they are gentle.
Great flying planes. They need some rudder in the turns as JWN mentions but what great flyers. It's really easy to get hooked on flying Cubs.
