Hello. Sorry for bothering you. Im David, im from Croatia, thats a small country near Italy, so as you can see im very far away. Here is only 2 services for dji drones, and they are very expensive. I bought a cheap dji phantom 3 advanced, i have never flown it because it shows esc error, but the seller said everything works, so he cheated me. I would like to have an advice from you. As i was looking online, if there is esc error , i need to desolder esc (mosfet) on a main board on a phantom, and resolder another esc. Is that correct? Im in need of help so im contacting you for a free advice. Thanks for taking the time to read this. Have a pleasant day. David.
