Bill's pdf shows something completely different. The pilot is holding
the stick too far back in the early stages of launch & the elevator is
pushing the tailwheel down on to the ground even after the
mainwheel has taken off. That's just poor technique & usually
happens because the pilot is behind the aircraft & blindly pulling
back after the glider starts moving.

A Discus is a "taildrager" which normally sits tailwheel-down.


Of course it is.

If a Discus pilot follows the technique recommended in the flight
manual then the tailplane will raise the tailwheel off the ground before
the glider takes off. Having the tailwheel rolling along the ground with
the mainwheel several feet in the air is not, and never should be,
considered a normal winch launch.
