The biggest difference will be going from tricycle gear to a tail dragger. The 4-Star especially can be a handful on the ground. Be ready to add GENTLE right rudder as you slowly advance the throttle for take off. In flight, the 4-star will be a little more responsive and aerobatic but still stable and fairly gentle. When it is time to land, the 4-star loves to float so you can easily overshoot your landing until you are used to it. You can also bounce a 4-star like a basketball on landing if you aren't careful. Be sure to release the elevator just before the main wheels touch or it may decide to bounce back up and fly a little more.

I would have an instructor or someone experienced around for at least the first 1-2 flights.
