Gosh, I cannot make anything out of your language translation to English.

Sounds like the tail rotor only swings one way or perhaps full on an input. More than likely need to set the gyro sensibility channel, I got the same effect until I set the gyro sensibility when trying to setup a FBL100 from nothing just trial and error.
