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

Make sure your pivot tube is at 23-25% MAC (Mean Aerodynamic Chord). That drawing looks close (it actually looks a tad forward) but if you don't have it in the right spot it can cause issues like excess servo strain or worse yet flutter or control lock out.
