The Cub is a forgiving taildragger.
It is indeed and this is a long thread, slightly done to death, but FWIW...
Harvey S. Plourde, he of 'The Compleat Taildragger', advocates one of the lower powered cubs -- i.e. 65HP -- as ideal for learning taildragging on. He reckons the Super Cubs (I presume he means 135hp up) have too much power and don't give you a really good feel and understanding for the various torque / gyropscopic forces etc. as it's all over too quickly.
I can see his point. In a 150HP Super Cub you're off the ground pretty much before you know what's happened and in the early days it's just a question of lots of frantic footwork and then a desperate leap into the air. Lower power would give you more time to suss things out.
Like I say, just a thought. Anyway, at the risk of getting flamed about it (again) -- buy his book!
