Exactly.

Do late model sailplanes actually have a "factory" grounding point?

Certainly not when they are in the air!

OK, that's a joke, but it does bring into sharp
relief that the "ground" concept is a fiction
(except under limited circumstances that are not
relevant here). It is also a fiction on the ground
as well, particularly where RF is concerned (see
any book on antenna design).


Am I correct to assume the best grounding point
would be the heaviest metal frame work closest
to the instrument panel such as the control yoke
or the adjustable rudder pedal track?

I doubt it, but read the service manual and contact
a competent engineer/technician. I would be
very reluctant to allow electricity to be conducted
through any part of the airframe.
