DJI
I need this mainboard cable to my transmitter can you tell me how to purchase it from your store? The cable was broken during a antenna upgrade (not by me) the transmitter is out of warrenty, their is no reason to send it in for a repair so simple.

check ebay, now and then remote parts pop up online.

Would suggest you to contact local retailers/repairs, they may be able to source the part for you from DJI

Anna, this accessory is not for sale in our website and I don't think we can send one to you directly from facility, please send in the RC for repair or contact local retailer/repair center for assistance.
