YU XIANG EC-135 RC Helicopter Malfunction

This heli is full of huge potential, maybe even a game changer for new heli pilots. Having flown brilliant little helis like the k110, eachine 130, 150 ,160 & 180, even the super capable OMP HOBBY M1, This type of model -including the eachine E 135, could make the introduction to flying RC Helis so much more enjoyable, mainly because of optical flow stabilisation.
However despite prepping the flight properly, gyro calibration, joystick calibration etc. I encountered this big problem, hopefully ill have a solution to this soon.

Tail rotor axis gyro failure.
