How to sync fpv goggles to your drone

Before you will be able to use your favorite fpv goggles, you will need to get the video transmitter and the goggles to work on the same frequency.

This is not hard. The video transmitter has a push button that you can use to change the frequency it transmits on. But what many people do while mounting the video transmitter onto the frame is this - they mount the video transmitter in a way that makes it extremely inconvenient to access the push button.

So if the frequency the VTX works on is clashing with some other frequency, it will cause problems - and they will not be able to easily change the frequency because they cannot access the push button.

So this is what you would want to do instead ...

You would want to get the VTX and the fpv goggles to work on the same frequency before you mount the VTX onto the frame.

Once you power on your quadcopter drone with the VTX connected - but not yet mounted onto the frame, the LED lights on the VTX should light up. There should be three LED lights on the VTX - red, blue and green. The green indicates whether the power is on or off.

The red and the blue LEDs let you know which channel and frequency the VTX is transmitting on. Consult your frequency chart to know which frequency the signal is being transmitted on.

Now, switch on your FPV goggles - or your fpv monitor - and see which frequency the receiver is tuned to.

Changing the channel on your fpv goggles

Your fpv goggles should be set to the same frequency as your VTX. You should have a list which specify the frequencies your goggles may be connected to. This should also be available online at the manufacturer's site.

Once you know which frequency the VTX is transmitting on, you can either change the channel on your goggles, or use the push button on the VTX.

You will want to have the frequency chart on hand while doing this. You can scan instead - but that takes longer.

If you are using a analog video transmitter and flying in the same area as other drone pilots, it's possible that someone else might be using a video transmitter that's way more powerful than yours. In that case, your fpv goggles will receive video feed from their drone and not yours. And you might crash.

So you would want to ensure you are not flying too close to others. Preferably, you should be the only one flying a drone in the vicinity.

Or else you could use a digital FPV system. Digital fpv sysems offer image quality that's immensely superior. And the latency is very low in comparison.

Either way, you would want both to be communicating on the same frequency.
