I agree that very little rudder torque is required for most jets and you could get away with less. With the Euro, the fin is large and you do not want flutter on this surface as it would cause possible loss of the aircraft. I have also seen flutter on a Rafale rudder which is very similar in shape to the Euro. I have also seen terminal flutter on a very small elevator suface with very short linkages, so I don't know if we appriciate the loads that these aircraft go through. For me, I would err on the side of safety! I as said earlier, if it is a T33 with a very small rudder, you could consider a less powerful servo.

I was hoping that some of the other more experienced jetjocks would pipe up and give thier opinions. Once again, please don't put anything less on a Euro! Mechanical advantage can also be gained from linkages, etc.
