The RCS of glass gliders is quite large because of all the metal push
rods. Tests with local radar (Luke Air Force base) showed no
significant improvement in primary target return if a corner reflector
was added.

I have been easily tracked by approach control in my ASW19 and had
them vector traffic round me as I climbed. They do have to want to
see you though and, as others have pointed out, it's likely that the
radar display will be set to filter out a slow moving primary target.
