With the popularity of recreational drone different accessories also flooded the net. And one of the accessories that made an advance development on its technology is the remote control. Remote control allowed us to control the drone at will, every year new technology is being added to it, new devices is integrated or paired with the device. Controller for drone is not just anymore using a joystick to go up and down, right now flying drone becomes more enjoyable with additional accessories to it now it is much more enjoyable to use with the aide of FVP goggles.
Anyway what is an FPV Googgles? FPV short for First Person View, a device that allow a user to have a wider field of view and a live view of what the drone is seeing during flight. Flying a drone with FPV put the experience into a the next stage, having an FPV goggle give the user a birds eye view, with this user enjoy the beautiful scenery, experience the feeling of flying. Aside from these, it is also much safer to fly the drone with the help of FPV.
Anyways before you fly a drone and buy an FPV, it is a must to learn some basic concept about the commercial FPV that you can buy in the market today. Know the details and how the drone works, read the things that you must consider for getting one, the frequency, the brand, the resolution and other technical features that you must learn in order for you to get the best FPV goggle for your drone and provide you a great immersive flying experience.
Learn the following about the FPV for Drone
Video Resolution – video resolutions on FPV goggles ranges from 640 x 480 to 854 x 480, there are higher ones but not that common. Of course the higher the resolution the better and much better for your eyes. A 640 x 480 is good enough to give a decent quality resolution. There are some HD FPV available in the market but of course it comes with the price. Common resolutions are 640 x 480 VGA and 854 x 480 FWVGA.
FPV Field of View (FOV) – the FOV is the angle that you can observe in the display in the FVP screen. When it comes to the field of view, the higher the better. Most of the FOV in the market right now is in 35+ to 45 degree view. Head Play goggles claim to have a 70 degree field of view, which is much better. But we expect that in just a few years time a 180 degree field of view will be the standard FOV in the market.
Best Frequency of FPV – frequency is also one of the most important consideration in getting an FPV goggles. There are several frequencies that you can choose, frequencies ranges from 900 MHz, 1.2 GHz, 1.3 up to 5.8 GHz. Expert suggest that the lower the frequency the better when it comes to penetrating objects and obstacles such as trees, hills and walls. So far 900 MHz are illegal to used in drones in some other countries. The 2.8 – 5.8 GHz is becoming the standard/preferred frequency for FPV in drones. Before buying one, make it sure that it is legal in your country to operate FPV in the stated frequency.

Head Tracking Technology – the head tracking technology allow the pilot of drone to control the movement of the camera in the drone. When the pilot move its head the camera also moves in relation to the pilots movement. This makes flying the drone a much more fun and great experience, giving the user more control to the drone as well as the video. Most of the high end drone with a rotating camera has a head tracking technology built-in.
Compatibility – before buying one make it sure that it is compatible with your current drone. Check the specifications, it’s compatible drones. Usually popular brands do have a wide range of compatibility . Popular brands are Fatshark, Skyzone and Boscam.

Best On-screen Display for FPV – the on screen display makes flying the drone easy as well as safe. See the ground speed, the altitude, vertical velocity as well flight time as well as the battery voltage right on the screen. Some FPV screen do have cluttered display , overloading the user with too much information that is not necessary. Some have a good lay-out and clear crisp text that doesn’t block the view on the screen.
Other Things to Consider
Battery for FPV – if you want a longer flight time you might want to check for the battery capacity of the FPV. There are FPV with built-in battery and its not removable while others have an extra battery pack to switch just invade you run out of juice.
Price – of course it is one of the leading consideration that you have to look at, buy an FPV that it’s worth the price. Don’t buy it just because it cost less or buy it because of it has a brand. Buy the FPV because of features and specs that you need for your drone and of course the price is reasonable.
