Hi,

I have noticed that most if not all modern gliders are built with a
T-Tail (not sure about the term, I am talking about the elevator being
located at the top of the tailfin). While most power-aircraft I know
right up to the airliners have it at the bottom.

It gets the elevator/ horizontal stabilizer up into cleaner air with fewer
flow blanking problems from the wing and fuze. Perhaps the biggest advantage is
that it gets the stabilizer up high away from damaging obstructions. I have
seen one low-down elevator get damaged in ground handling and it was not a
pretty sight.

What are the aerodynamic or constructive reasons for that?

Ciao, MM
