Before paying for an order you may need to triple check what your getting. Their product is awesome, but their conduct of business is slightly on the shady side.
The X-3D Gyro is a professional substitute of the mechanical gyro that came with your X-UFO. It is a three-axial Heading-Lock gyro. That means, your X-UFO will always try to keep its actual orientation at neutral control commands. It will change its orientation in the axis corresponding to a stick moved, respectively. You will have to get used to this new control system if you are used to flying with the mechanical gyro. However, after a while you will be able to concentrate on flying - not only hovering - your X-UFO. With some more experience even loops are possible! Temperature compensation enables your X-3D to work in summer as well as in winter. It is pretty shock-resistant due to the use of very modern Piezo-sensors. With the three axial Heading-Lock function the pilot is able to return to a stable flight position after fast turns with ease. In addition, flying forward with high speed is very easy, as well. The X-3D gyro offers four different modes, which can be selected by jumpers. The pilot can always adopt the behavior of his X-UFO to his skill level. Furthermore, the best flight parameters for other tuning measures can be selected. Using the USB-interface, all parameters determining flight and control behavior can be changed. Thus, the pilot can adopt his X-UFO to his very own preferences and needs. The USB-interface can be purchased separately
