The drone was in freshwater for about 5 mins. I removed the battery as soon as I recovered drone, dried it off completely, and stored in rice to help remove any moisture. Everything moves freely. I tested the battery that was submerged, with another drone and it worked fine. After 2 weeks, I tried powering up the drone and does not power up. I've done several repairs myself and wouldn't mind doing it myself, I'd just need to know what to replace. That's what I need help with. Any help will be helpful. Thanks
