  10. thank you for all the information. I'm about to start building my first quad, and I bought a CC3D board with openpilot only to figure out they split the company. I want to use cleanflight/betaflight or raceflight on the CC3D so do I need to use an ftdi adapter to flash the correct fw? thanks if you get this

  17. When I was in college, the bootloader was explained that the first part of starting your day was to pull your boots on by the bootstraps. And cache was a storage for trappers or hunters. You are becoming the goto guy for any and all problems RC and other related. You SIR are an absolute genius of how you present your tutorials, if not for you I would be doing a lot more surfing for the correct way to approach a problem. Please keep up your excellent work for the RC enthusiast.
