when i bought mine it was advertised to include the x3 gimbal lock. i didnt get it in the package so messaged them and they sent one and i got it a few days laterThe gimbal lock they include is for the X3 not the X5, that's why I had to get the X5 lock
also purchased this for my Z3 and works much better
