This is the brains of your CX10, if you have been rough and damaged your main board the quad may behave erratically or drift excessively. If  you have already checked the blades motors and controller for issues then you likely will need to replace this main board to restore normal flight.

Things to remember:

• This is the standard PCB board and does not include motors or the battery, you will need a basic understanding of electrical soldering as in order to install this you will need to dismantle and solider the motors and battery to this board and then reassemble the quad.
• If you do require any repairs contact us as we can fix them up for you (at a cost).
