Firmware for Naze32 rev6 using Cleanflight on Mac OS X

Update (25-Apr-2016): Check out the video on Flite Test. If their instructions don't work, feel free to try what I did listed below.

Here's a short guide for anyone using a Mac to install the latest Cleanflight firmware in a new Naze32 rev6 flight controller. At the time of this writing, Cleanflight Configurator is version 1.1.0 and the Naze32 firmware is version 1.11.0.

  • Solder a bridge across the two pads marked "boot" on the board. See Figure 1. I did this simply using a bare wire; very easy to remove later.
  • Figure 1. Solder bridge across Naze32 boot pads.


  • Do not attach the Naze32 to your Mac. Be patient.
  • Download and install the USB to UART Bridge VCP Driver.
  • Download and install the Cleanflight Configurator at the Google Play store.
  • Restart your Mac.
  • Open the Cleanflight Configurator app in Chrome.
  • Do not make any changes to the Welcome screen. Switch to the Firmware Flasher by clicking the tab in the sidebar.
  • Figure 2. Switch to Firmware Flasher.


  • Choose the most recent, stable NAZE firmware from the drop down menu.
  • Switch on the options for "No reboot sequence", "Flash on connect", and "Full chip erase."
  • At the bottom of the window, click "Load Firmware [Online]".
  • Figure 3. Options in Configurator.


  • Connect a USB cable to the Mac and then the Naze32. The flight controller should only illuminate the blue LED.
  • Click "Connect" at the top of the window. The firmware will now transfer to your Naze32. An orange progress bar appears at the top of the window (sorry; no screen capture). LEDs on the Naze32 will not flash to indicate a file transfer. Instead, expect the LED to remain a solid blue.
  • Once transfer is complete (requires less than a minute), close Cleanflight Configurator and then disconnect the Naze32 from your Mac.
  • Remove solder bridge that connected boot pads in the first step. Desoldering braid works well for these small pads.
  • Re-open Cleanflight Configurator.
  • Connect a USB cable to the Mac and then the Naze32 rev6 board. The board should illuminate blue, gree, and red LEDs. Once the Mac has recognized the Naze32 (within a few seconds), the red LED will stop flashing and you will see a solid blue LED and a flashing green LED.
  • Click "Connect" at the top of the window and have access to the many configuration screens for the Naze32.
  • Since your Naze32 now has Cleanflight installed, you will not need to solder a bridge again in the future. If you choose to later install a new version of the firmware, do not choose "No reboot sequence" from the Firmware Flasher.

    Good luck!

    Team Durango DEX210: My complaints while building

    For the past several weeks, I've been assembling a Team Durango DEX210 2WD buggy for my son. I have built quite a few RC cars in the past but I must say that this kit has been a real challenge. Although the parts fit together quite well, both the kit's organization and mislabeled instructions have made construction pretty rough.

    Finding Parts

    So far I've spent more time trying to find the parts than actually putting them together. I'll openly admit my complaint is rather petty but this really is annoying. Most manufacturers label parts trees alphabetically (i.e., A, B, C) but Team Durango uses a non-sequential 6 digit code. I had no idea that such a small thing like this could be so frustrating. Since there is no diagram of the trees within the manual (Tamiya's kits have clearly spoiled me), it can take several minutes to find each part. Bagging plastic and metal parts together (like Team Associated) would have also made things so much easier. If you have a lot of space to lay out the trees - like a dining room table - take advantage of it.

    Poor Manual

    Perhaps even more frustrating is the poor manual. On several occasions I found incorrect part numbers. While I'd much rather have a paper manual to guide construction, you can download an updated file from Team Durango. I would've appreciated a list of errors so folks like me could update the manual - well, manually!

    Even with the updated file, you'll still be at a loss to find any meaningful description of the numerous choices you must make during assembly. One of the biggest selling points of the DEX210 is the amazing amount of adjustments you can make to suit your driving style and track conditions. However, some of the ways Team Durango offers these adjustments are unique and difficult to figure out on your own. I found myself spending a lot of time in online forums and various web sites to learn what I believe should be in the manual.

    Aftermarket Shock Caps

    Stay away! I learned my lesson the hard way on this. I bought a set of STRC Aluminum Upper Shock Caps but quickly learned that they did not fit the stock plastic pivot balls in the kit. After scratching me head, I realized that the pivot balls on the base of the rear shocks would fit. But this is a metal-on-metal connection and there's a lot of play in the joint; a properly sized bushing would be a better choice. I found some others online have tried the metal pivot ball solution with mixed results. After all that time I spent loading the shock oil, I decided to go back to the stock plastic parts.

    Steering Plate

    It sure didn't take much force to break the stock part. While I was connecting the steering turnbuckles, I snapped the plastic steering plate. I guess I should be happy this occurred during construction rather than seeing my son break the part while driving on the track. As soon as I did a search for a new part, I discovered Team Durango makes a metal replacement. Gee, I guess even the manufacturer realized this was a weak point.
