Here's my problem:

The tailfeathers of my Kyosho GeeBee-Z is set up so that the right and left must be installed separately. The connection for the push rod is on the left stabilizer only. In order to get the right stabilizer move up and down together with the left, a " [ " shaped piece of metal is used to connect the left with the right. It does not, however, serve as a hinge. CA hinges are used on each stabilizer. I had a few questions regarding this setup:

1. The " [ " metal piece fits INTO the balsa wood of each stabilizer half. Yes, I had to drill holes into the narrow side of the stabs for the metal piece to fit into! Over time and use, the metal piece will open up the holes and create play between the two halves of the stablizer. What can I do to prevent this? Should I glue the metal piece in there to ensure that it doesn't move? Again, it is not a hinge. It is only a connector between left and right.

2. OR....would it be better to find some kind of Y-shaped pushrod that attaches to each stabilizer, thus eliminating the need for a connection between the right and left side? When I say "better", I mean less potential for developing play between the two stab halves.
