Hello nihao, I not post in long time, lol happy new year. Ok so mavic pro I have crash and body on side pry open just little but I use knife so I close it, but back left motor on end of leg broke off, I never get insurance because at time I not know how, but I want know is possible just buy part and treat as normal broken electronic and just replace broken motor and see it if work. But plan I have, I want see if I fix it then if it have sensor issue, then I send to dji so they fix error, this is ok for me do or? I just not want pay price they give for leg, motor ect when I get it cheap in amazon. But what you think I need do, or plan I have good?

I guess that is a good idea, if you can fix it, it would save some money, but there will be some fine soldering which if you get wrong could cause damage to the ESC circuit board and cost more to repair
