ORIGINAL: GSR
I'm with Hyperdyne on this one. I do not know the math behind the workings but I do know from empirical data that every time I have placed a gyro towards the nose of the aircraft they dont work well at all-when I have moved the gyro to the center of yaw (which is close to the CG) they magically work wonderfully.

Exaclty the same happened to me. Although I have not yet moved the gyro close to the C.G., I noticed that I needed to increase the gain with respect to the ailerons gyro that is positioned in front of the rudder/nose wheel gyro but in the center of the roll axis.
Although in flight, the first time I tested it, without gyros, my turbine jet (Skymaster F-16 1/8) under cross wind flight, she had wagging tail and wagging wings.
In the next pass, I turned on the ailerons gyro and wing wagging stopped but tail wagging continued.
In the next pass I turned on the rudder/nose wheel gyro and the jet flew like a rock.
My gyros are ACT Fuzzy Pro airplane gyro.
My problem moving the rudder/Nose wheel gyro back close to C.G. is that the cables are not long enough so I would need Heavy Duty (and maybe amplified) servo extensions.
For now, I think it is working and this jet is easily handled on ground while in take off.... I have nose wheel expo at -40% for each side (Futaba expo is negative while JR is positive I guess).

Sorry for the 0.57 minute censored video (some guy was yelling bad words....) and for the landing censored (hard landing that broke the legs suports and made the guy on the camera run away. He was too close to the runway side line), but anyway, watch minute 2.15 to 2.20 aprox. and you can see the wings and tail wagging and in minute 3.18 to 3.24 you can see that in flew like a rock.....
