First post on dronetrest. I flashed an RSSI mod firmware on an FS-X14S then on my first test I smoked the FC. To be honest I don’t think it had anything to do with the receiver firmware but whatever happened I see a relatively large component on the FC is discolored and swollen up and it is roughly where I saw the smoke. See photo below. I actually don’t know what the component in, maybe someone can help me identify it and what’s its purpose is?
The FC is still working when connected to a computer and the ESC is talking to the FC fine. I am planning to desolder and resolder everything on the FC and try flying it again while I wait for a new F7 controller.
Just want to know if anyone knows what that component is (the Kakute manual shows a “coil-like” symbol) and what impact it will have to the function of the FC.
