Hi,
As many of you requested I finally managed to do a How-To diagnose a Flight Controller video. I explain the basic diagram of an FC, usual faults and what to look for. Hope I made it simple and easy to understand and if you have any questions please leave them in the comment section or follow me on social media.
If this is well received I will make more how-to's on other components(ESC, VTX, PDB, etc)
