I may Be a beginner but i have already found out that the harder of the two is the tail dragger, i have three planes myself and all three are tail draggers, one is a superchipmunk with a O.S. FS-91, a dragon lady also with a O.S. FS-91, and one big trainer that i am trying to find out the make of as i type this it has a ASP 120 two stroke, the ground charcteritics of a tail dragger is harder to control on take off and landing, i have heard that sig makes a good type of "trainer" that is a tail dragger, the question is are you comfortable enought to solo with a tail dragger after getting used to whatever you have preveiously flown.
