  1. Remove Props and pull apart Falcon 250
  2. Download OpenPilot GCS 15.02.02, You may also need the STM32 Virtual Com Port driver.
  3. Install the Cleanflight Configurator from the Chrome Web Store.
  4. Download Cleanflight 1.10 firmware .bin or Latest Betaflight CC3D BIN File from here
    NOTE: You need .bin file – so thats why we have put Cleanflight 1.10 ONLY, versions after this do not have .bin file.
    For difference on Cleanflight vs Betaflight view this article.
  5.  On openpilot and open the firmware tab. Click rescue then plug in your Racer to computer via USB (no power)
  6. Click open and select .bin that you downloaded.
  7. Click the checkbox, I know what I’m doing!
  8. Click Flash
  9. WAIT TILL 100%
  10. MPORTANT! Leave usb plugged in and power the board via esc input
  11. Click boot (in same firmware window), motors will beep and wait till blue light on the cc3d is steadily blinking
  12. Close openpilot
  13. Unplug everything
  14. Open cleanflight
  15. Power your copter and plug usb back in now.
  16. Click connect. (if it fails, try changing the port)
  17. Congrats! You now are on Cleanflight. To connect your Falcon to Cleanflight you always need to use power now, plug in your battery!
  18. Place Copter on flat surface and under setup, click calibrate accelerometer.
  19. Change minimum throttle to 1050
  20. Change maximum throttle to 2000
  21. Click Save and reboot
  22. Now goto your PID tuning. Change your settings to the screenshot below. You need to Click Show all PIDs
    MAKE SURE YOU CHANGE TO LUXFLOAT AT THE TOP FIRST before you change all the values.

  23. Now goto receiver tab, and check all your transmitter channels are correct, they usually are different and you will need to reconfigure.If you have the Falcon RTF and have the I6 receiver, THIS IN THE MONEY PHOTO! This will save you so MUCH time by copying below cables.
  24. IMG_20160229_181507 IMG_20160229_181453You may want to try the following changes as well if you do not have the above, or you can look on google images
    Ch 1 moved to Ch3
    Ch 3moved to Ch 5
    Ch 4 moved to Ch 1
    Ch 5 moved to Ch 4
    (You may need to swap Ch 2 and Ch 4 around if your pitch and roll is incorrect.
  25. Now on the right (still receiver tab) change throttle to 0.50, throttle EXPO to 0.00, RC rate to 1.00, RC expo 0.00 – Save
  26. Now you want to set up your AUX Switches, open the Modes Tab.
    No mode selected = ACRO+ / Rate mode by default.
    Altitude mode = Angle Mode
    Rattitude  mode = Horizon Mode
    If you your switch only has two positions it would look something like this.
    2016-03-03 16_43_16-Cleanflight - Configurator
    0 = Horizon Mode
    1 = Acro/RateIf you have a switch that has 3 positions it may look like this.
    2016-03-03 17_07_58-Cleanflight - Configurator
    0
     = Angle
    1 = Acro/rate
    2=Horizon
  27. Now save your settings. By moving your switches you should be able to test the setup. Green = mode activated, grey means Acro/Rate mode.
  28. Now we need to calibrate ESC,  go to the motor tab. remember, you should have removed props at the start, if you didn’t, DO THIS NOW.
  29. Unplug battery
  30. Slide Master to MAX
  31. Plug in battery, wait for beeps.
  32. Slide Master to MIN
  33. ESC Calibration is now complete,however you must test that it has worked corectly.
    Arm copter, and all motors should spin at 0 throttle. If only some do, you need to redo the above steps until they are all spinning correctly.
  34. You now need to swap motor configuration as clean flight configuration is different as per below.
    LEFT is openpilot RIGHT is Cleanflight
    54da3c8a6ab4457e8f1b5df20ab563714_rotor_quad
    cleanflight-motor-direction
  35. Copy and paste the below into the CLI tab.
    mixer custom
    mmix reset
    mmix 0 1.0, 1.0, -0.93, -1.0
    mmix 1 1.0, -1.0, -0.93, 1.0
    mmix 2 1.0, -1.0, 0.93, -1.0
    mmix 3 1.0, 1.0, 0.93, 1.0
    save
  36. Your cc3d will reboot. Give it a test flight! Make sure you are open space in case you missed a step and it crashes.

  1. Thanks for this great tutorial. It’s been really helpful. I have a small problem though. I have the Falcon 250 and I cannot get any kind of response from copter when using my flysky fs-i6 transmitter. I have connected everything as showed on the images and done the esc calibration. The motors spin correctly as well.

    Do you have any idea what the problem can be?

  2. Wow, thank you so much for writing this and updating the links. My quad felt unstable and gave me heart attacks before switching to clean flight. If I used a past version of betaflight would that be similar to a stable version of cleanflight, or should I still expect some bugs?

      1. Thanks for the reply. I’ll give 2.5.3 a try, and maybe later on if I feel lucky I’ll try the newest release, hard to fly with my fingers crossed though, thanks again for the great how to!

  3. I have been using these settings for my Falcon 250, everything was working fine until I installed the 3 blade rotors 50×3.5×3, now I have a bumpy ride when hovering is this normal? How can I fix it?

    1. You need to follow a youtube tuning guide to retune your quad. search for PID tuning on youtube.

      You can also try Betaflight 3.0

    1. after 10 seconds of beeps you can move to next step. Some escs dont “finish” the calibration beep and just keep beeping

  4. Hi there, quick question, when I open up my pid tuning page it wont let me put in any decimals as stated by the pictures. I also noticed that when I downloaded cleanflight my configurator read 1.2.4 and not 2.5.3? I’m not totally sure on how to download any older versions? help?
    Thanks

  5. Hi, it is a very good guide. But i have some questions. I have a Falcon 250 Pro with a SPracing F3 fc and i was on cleanflight. Now i have flashed the newest version of Betaflight and i’m not sur if i must also do the CLI mmix? i need some help?? Quad is hovering but when i pitch foward the quad returns itself and comes down.
    So i asume that i have to enter the given CLI mix command on my F3 ?
    I am new to the hobby and a little confused

    Thanks
