HOLDING ON THE TAIL
Removeable h-stabs are common. Glue sitck ( at your office supply store) Commonly used to stick pieces of paper together for "paste-up" boards or foam core display boards. Plenty strong for paper, but it won't form a strong bond to wood or carbon or metal. Just enough.
The goal is create some friction or adheasion, not to bond the tail to the rod. Well known to experienced glider pilots.
bees wax, it is sticky, not slippery like parafin wax. You would not use this to lubricate your wooden drawer slides.
On my Sagitta 600 I just bent the metal rods slightly so they were not perfectly parallel. Flew it that way for years with nothing else to hold it on.
