Hi guys,
I bought a second hand nazgul 5(the v1) and started flying it, eventually I crashed hard enough for the flight controller to be ruined(pads broke off). So I bought the speedybee f405 v3 fc and have set it up with the XM+ receiver and configured all my settings. However I added it into my frame today and plugged it into ESC for first time. I plug the battery in and hear 5 beeps, however the fc only has a faint red light and neither vtx or Rx have power. When I checked the pads with a multimeter they were -0.3v or 1.6v. I'm not great at soldering and don't have flux or a very good iron, but when I checked for continuity there were no shorts anywhere.
Anyone know what might be going wrong?
