I have a phantom 3 4K that the gimbal stopped working.. I can't get no video so I want to replace the gimbal but I don't want to pay $500 for it ..if anyone has a used gimbal they want to sell or a gimbal main board let me know. I just got it back from DJI repair and all they wanted to do was sell me a new camera /gimbal for $500.. for that much I just buy a mavic 2..thx
