Hi Peso,
Another 2 cents worth>
Would believe right turn problem is mechanical, something is altering,
possible push rod, linkage or servo.
There is a servo developed especially for Gyro control and it is a jewel;
If desired take a look at it> FMA Direct model # PS905MBB
Stability>lateral area is important. You have an "open" work pylon? Try
enclosing the thing so that area wise it would be same as a"solid" pylon
Not mentioned is size and power of your gyro?
Good luck,
