Duncan et al,
Kind of interesting, that. The Mark 4 Harvard (plus the T -6G
model) had the tailwheel swivel slanted somewhat forward at the bottom! I
asked why as we transitted to the machine, and the Big Boss said it made it
easier to land because the tailwheel became self-steering and fought the
tendency to groundloop early into the touchdown and stoogents had less
trouble with it. It was restricted in this travel each side. I concur it
worked, but the apparent relaxation from primal fear was the undoing of
some. One can see both sides of the topic............
Cheers, ferg
