Drone: Flight Controller (Revolt v3)

This entry is part 2 of 6 in the series Quadcopter
Hey. This page is more than 6 years old! The content here is probably outdated, so bear that in mind. If this post is part of a series, there may be a more recent post that supersedes this one.

So my wife got me a drone – it came as a ton of bits. I Googled around but did not really find an all-in tutorial on how to put all the bits together to make something that might fly, so I decided to wing it (hahahaaa). I started with half building the frame then got sidetracked by the flight controller.

The flight controller I have is a Revolt v3, by RaceFlight. On the package, it says ‘Get documentation at www.revoltfc.com‘, so that’s where I went. The website has a series of videos but rather throws you in the deep end at the get-go @DFU Flash Revolt.

My version of ‘DFU Flash Revolt’

  1. Stick the Revolt v3 in DFU mode as per the official video, by “jumpering the two jumpers” and plugging into USB on your PC. I actually think there’s just one jumper – you…or your tweezers. I have no idea what the things you are jumping are called. Contacts? Jumpees?  The (blue) light ought to come onto indicate DFU mode. Incidentally, DFU stands for Device Firmware Upgrade…I think it’s an iPhone thing.
  2. I’m running Windows (win10). It installed some drivers when I plugged in (in DFU mode) and then told me my ‘STM32 Bootloader’ device was ready‘. The Official video tells you to need to change this to Win32 drivers.
    • Head off to here and download Zadig. Its an EXE file so it just runs out of the box. This is the missing step in the official instructions 😉
    • Do what it says in the official video, switching STM bootloader to Win32.
  3. Download the FlightOne control software from flightone.us/download and the most up to date firmware from the same place (a *.bin file). ‘Install’ the software. I use quotes as there’s no installer – you need to unzip the file to a folder and run FlightOne.exe

    Run me! I’m in the ZIP file

  4. Your Revolt v3 flight controller module should still be plugged in (I never told you to unplug it) and still in DFU mode (with the blue light). When you load FlightOne following the careful instructions above it’ll detect DFU mode (now you have the driver set as WinUSB – would not have worked if you tried with STM32 Bootloader driver). FlightOne will now give you the opportunity to upgrade the firmware.
  5. I chose ‘upgrade from file’ and selected the firmware file (the *.bin one) I downloaded in step (3). It’ll do its thing for a bit – you can watch the progress bar, or watch this video about progress bars 😉
  6. When done, close the FlightOne software, unplug the Flight controller from USB, restart FlightOne and plug back in the USB.
  7. Now you should be into the FlightOne software proper (it’ll detect your Revolt) and you’ll proceed with a bit of setup.
  8. I was asked what receiver I had – I choose Taranis as I recognised the word from the box inventory. That’s as far as I’ve got…

Taranis. I recognised the word, and the green one looks like the one I have. Incidentally, Taranis was a Celtic/ Gaul god: the god of thunder. apparently, when the when Romans they rolled the hordes Taranis came to be syncretised with Jupiter…the big guy on Mt Olympus.
