FWIW my ex-Zlin owning friend with Chipmunk experience raised his eyebrows a little at the idea of a no-tailwheel time pilot transitioning quickly into something that might resemble a Spitfire. He also waived off the Zlin versus Chipmunk question as relatively unimportant. His thought was step (1) lots of tailwheel time in *anything* with a small wheel in the rear followed by (2) Harvard (AT6) time. That is assuming the scaled Spitfire flies like a full scale version. He was a US Navy test pilot so I think not a bad guy for questions of this type.
