This the first place I’ll send anyone wanting to fly taildraggers. There’s a lot of books out there – this one is my favorite intro. Harvey Plourde does a great job – and I end up teaching with a lot of the same terminology.
A lot of tailwheel is about waking those feet up. But, that’s not nearly enough. The Flying Fiddler (Dustin) does an outstanding job of addressing one of the biggest deficiencies (and sources of ground loops) that I see in taildragger pilots.
