If the airplane has a short tail, the airplane may ground loop on take off. Poor correction can lead to problems in a cross wind. You have to switch from taxi to flight during take off and not after lift off. The rudder is less effective than the wheel below it, you have to use it after you touch the ground and roll to a taxi. I train students, all the planes I train with are tail draggers. Its always easier to go back to a nose wheel.

A great intermediate plane .40 and .60 is the sig fourstar. It is a very stable tail dragging platform. I don't Recommend the 1.20 version.
