After a long inspection and some test I found the problem, the servo input is well reversed in the TX and all work very fine exept that the axis gyro in the receiver are not reversed and still make their correction in the wrong direction.

Is there a way to reverse the axis gyro movement, or I will have to change the motor polarity in both servo?
Have you try to diminish balance pot near minimum? ele & ail near center? eems that digital servos are too fast for RX to control.
