Default RE: Building a full flying stab for my SU-27

Flying stabs are very common with sailplanes. On most, the "axle" rod and "actuator" rod both slide into a metal tubing or other materialed receiver which is epoxied into the stab itself. This allows the stabs to be easily removed for transport. A slight bend in the rod (friction) holds the stab on. Sometimes beeswax or other material is applied to the rod to "sticky" them up, and even set screws have been used. So long as your stab is aerodynamically balanced, the stab should be less likely to flutter.

Also, don't deceive yourself and think this setup will not work for a powered plane also. Most full house thermal and slope sailplanes have very wide speed envelopes (a DS sailplane has set a speed record of over 300 MPH). Take a look at a sailplane setup too, before you commit to your design.
