yep my rudder servo was way up front in the nose connected by some flex rod through out the aircraft. thought that was stupid so I took the thrust tube out and stuffed a little hs-81mg servo back there.
Works great!!
I figured it would not be a problem with that tiny servo as it's metal geared and has plently of torque plus it's only going to have minimal deflection for short 4 point rolls.

My elevator and throttle servoes are in the tail as well under a pannel on the left side of the virtical fin
