Gents,

Maybe interesting for you, my own design method to couple two elevators on the pushrod, as by my Taurus. So with central and intern connection!

Try to make a bras bearing with grease because after mounting it is not servicable animore.
This picture is taken before lowering and glueing the horizontal tailplane in position.

The Taurus do make nearly 400 flights now without problems on this detail.
Second picture Orion, about 150 flights, same linking.
These linking is used by Ed Kazmirski in the kits from Top Flite models Orion (1960) an Taurus (1963).
