Orqa FPV Headtracker setup guide

In this guide we are going to use a Taranis QX7 to set up the headtracker.

The procedure should be similar on all radios that are running OPENTX firmware.

To use the headtracker you are going to need your goggles, radio and one AUX cable.

3.5mm male to 3.5mm male audio cable will work just fine, nothing special is required.

The procedure is simple and will take you around 10 minutes to complete.

The first step is to connect your goggles with the radio. 

Locate the trainer/head tracker port on your radio and connect one side of the AUX cable to it. 

Remove the rubber protector from the head tracker port on the goggles and plug the other end of the cable to it. 

Turn on your radio and go to the model setup. 

Scroll down until you see the “Trainer” option and set the trainer mode to “Master/Jack”

Turn on the goggles and go to the menu. Navigate to the “Features” tab and select “Head Tracker”. Set the Head Tracker to ON. 

Place the goggles on a flat surface and set the zero point. 

The flat surface or a table will be used just for the set up. In future when you want to use the head tracker, you would set the zero point while the goggles are on your head.

You need to set the zero point every time before using the head tracker so that the goggles know which way you are facing.

At this point the goggles should be sending the head tracker PPM signal to the radio.

Next, on your radio, go to the “INPUTS'' tab. We need to create 3 inputs for each channel of the head tracker. We will start by creating each input first and naming them so we can recognize them later in the setup.

Head tracker has 3 axis which are pitch, roll and yaw. We named our inputs accordingly.

Select one of the inputs, long press the wheel and press edit. Go to “Source” and select the head tracker channel on which you get the desired axis. Repeat this step for the remaining 2.

In our case we had to set source to TR1 for yaw, TR2 for pitch, and TR3 for roll.

Once that is complete, the inputs are completed and now we can move to the “MIXES” tab so that we can tell the radio on what channels to send the head tracker data.

Go to the “MIXES” tab and now you have to decide on what channels you want your head tracker axis to be on. 

In our example, we are going to use CH5 for pitch, CH6 for roll, and CH7 for yaw.

Long press on the desired channel and press edit. We would recommend you to give each mix a name so you don’t get confused later. Scroll down to the “Source” option and match the input with the mix. Repeat for the remaining 2 mixes. 

After all of the above is done, the radio will send head tracker signals on the channels you assigned it to. 

When you set the zero point on your goggles, every channel of the head tracker should be at 50%. If that is not right, you will need to calibrate the inputs we created earlier. 

Go back to the INPUTS tab and adjust the graph by tweaking the Weight and Offset options. 

This is how our settings look when everything is configured.

Note that this doesn’t mean that it is going to be the same for you. It depends on the gimbal or servo motors that you are using.
