While discussing tailwheel weight I wondered why we need a tail dolly?
Why do most modern sailplanes have fixed tailwheels yet SGS gliders
have castering tailwheels. Shouldn't we have a caster instead?

Schweizers are 'nose draggers'. The CG is ahead of the main, so they
tend to follow the rope on the runway. A CG hook tail dragger with a
castering tailwheel would be .... very exciting on the ground, but not
in a good way.
