You better stop while you are ahead. You realize of course, that if you have that cute lady with the nice smile teach you to fly in that cool little slice of history, that its all downhill after that, most other planes are going to lack something. Its kind of like after a years as a school boy eating at your cafeteria, going to a 4 star restaurant!
I have a J3 Cub, great trainer and all around fun plane.
There are a few simple concepts to learning tailwheel flying, please send me a P M if you'd like to talk about it with me. Good luck,. and once you master the Cub, go look for a Stearman to get some dual in, that is advanced training.
