I once saw a glider loose its horizontal stabiliser (hit just below at
the top of the T tail).
The glider bunted ,ie negative nose down ,that would throw you
out.
to do inside loops the stick would have to be hard back but I didn't
think the duo had sufficient elevator authority to loop in 3 seconds.

If the front drag pin failed and changed the angle of attack of the
main wing it might, but why would it.
Saddend and baffled .
