Jim,
Thanks for that - I'll go with the Loctite and cement the central (main
drive) coupling too.
If you haven't fitted the top yet, it's still possible to disassemble the
tail plane tube, slide along the fittings and clean up the areas of
contact. I'm a bit loath to bond while it's exposed for fear of the
Loctite going off before it's finally located.
