Ok so I purchased a broken radio from someone. Actually they tried to do the DBS mod themselves and cut through the #2 and #4 ribbons inside the radio. Everything works but the gimbal knob and the video record button. I bought it for 25 dollars. I have tried emailing DJI about parts for a week now with no response. Has anyone on here had any dealings with them on buying parts, or know of someone with a broken radio as well willing to sell some parts?
