Upgrading your 350 QX to Firmware 3.0 - Using PC interface

We've heard that some of you are having issues updating your 350 QX to use the new PC interface. Its important to remember that if you are using older firmware (Original release or 2.0) you will need to upgrade to the 350 QX3 release firmware that is now available on our website here:

We made this easy to follow guide to help you with installing the firmware so you can start using the PC interface immediately.


Step 1: Download New Firmware

Once you've downloaded and installed the PC interface  HERE and the FTDI drivers HERE for your multirotor programmer (BLH7840) you will need to select the "download new firmware" link on the first screen that pops up on the PC interface. See photo.

 Step 2:

Install the firmware that you just downloaded but clicking the "install it" button highlighted in the picture below. Make sure you save it to a place that you can easily access such as your desktop.

 Step 3: Selecting the firmware file and USB port

The next screen you will see is the firmware update installer screen. Here you will need to select the firmware file. Its likely that the program will automatically find the file for you, but you may have to select the "..." button to choose the firmware file you just downloaded. After that, you need to select the correct COM port that your USB multirotor programmer cable is plugged into. Here you see that ours was defaulted on COM 3 but needed to be on COM 14.

Once you have these two things selected, go ahead and hit update.

 Step 4:

You will now see this screen. Make sure your 350 QX is plugged into the multirotor programmer cable and is not powered up. After you have it plugged in and you see this screen, you can now power on the model to begin the update.

Step 5:

This is the screen you will see when you fire up your 350 QX by turning on the switch. The firmware file should automatically start downloading. Make sure not to turn off your PC or the 350 QX during this process. If you don't see this screen pop up, its likely that you have the wrong COM port selected and should go back the the previous screen to correct that.

Step 6:

When the firmware update completes, you will see this screen. You can now restart the 350 QX by cycling the switch.

 Step: 7

Once you cycle power, you will see the PC interface working properly! You've just completed the update! Make sure that you've adjusted your radio program to the new QX3 settings as some of the functions have changed.

Congrats, you did it!

How to Calibrate Your DX4 Gimbals

If you own a DX4 or received one when you purchased your 350 QX2, you may want to calibrate your sticks every so often to keep your radio running in tip-top shape. If you also have noticed that your 350 QX2 is making a beeping tone without any input in Smart Mode, a calibration is required. 

Step 1: In order to get into the stick calibration mode, you first need to make sure your flight mode switch (front left switch) is in position "2" (lowest position) and the Return Home switch (front right switch) is in the "Home" position.

Now, hold both sticks in the lower left corners and simultaneously hold the bind button while turning on the radio. Once you hear a series of beeps, you can then release the sticks and bind button. The far right green LED will flash indicating the radio is in calibration mode.

Step 2:  Start with left Gimbal. Move and hold in the lower left corner and press BIND button one time, “beep beep” will be heard.

Step 3: Move left Gimbal to center and press the BIND button one time, “beep beep” will be heard.

Step 4: Move and hold the left Gimbal to the upper right corner and press the BIND button one time, “beep beep” will be heard.

Step 5: Move and hold the right Gimbal to the lower left corner and press the BIND button one time “beep beep” will be heard.

Step 6: Move right Gimbal to center and press the BIND button one time, “beep beep” will be heard.

Step 7: Move and hold the right Gimbal to the upper right corner and press the BIND button one time, “beep beep” will be heard.

A series of tones will be heard and the LED will go solid, calibration complete 

We hope this helps!
