Important Notes: 

  • Before soldering or mounting any flight controller, connect it to your PC and verify operation
  • Incorrect soldering techniques will damage this board and void warranty. Please use the correct sized tip, temperature and technique. Temp controlled soldering irons (such as the TS100) are available for under $100 and will make soldering much easier.
  • Lifted pads are a result of incorrect soldering techniques or excess mechanical pressure and will not be covered under warranty. 
  • USB ports must be handled with care, breakage of usb ports are not covered under warranty
  • Always use a smoke stopper before powering your build for the first time.
