GoPros are currently the most widely known and highest-quality action cameras on the market, and are generally the best option for recording FPV flights.
screen display options are distracting. Luckily, most cameras allow you to turn this off. Finally, action cams can
primarily used in security systems, they do have some video characteristics that are particularly helpful for FPV. Board cameras usually have good low-light performance and can see into shadows. Board cameras also sacrifice color accuracy for high-dynamic range, meaning more light gradients are let into the camera at the same time. For example, you can still see clouds and see details in shadows at the same time. Most cameras can only see one at a time, such as details in the shadows, but on a completely white, blown-out sky. High-dynamic range is incredibly important when you’re flying around an area with a lot of changing light consistencies, such as under trees then into an open field, and all below a bright, cloudy sky. Board cameras are perfect for just flying around. But what if you want
to record decent video? If you’re more concerned about image quality, go with an HD camera that records locally to an SD card. Many FPV pilots have adopted sport- action cameras to record and to see during flights. Action cameras such as the GoPro (

sony.com), Mobius (
mobius-actioncam.com),
and keychain cams are all good cameras to stream video from while recording. They usually have an onboard battery, so you wouldn’t need to power them with an external battery, which can help save weight. As I mentioned
earlier, there are some downsides to HD action cameras. The HD image can look fuzzy after being transmitted over standard definition. They need special cables to connect to video transmitters, which are sometimes hard to make or find. The transmitted image from an action cam is also darker and has more color than a board camera. The exposure also takes longer to adjust when going from shadows to bright light or vice versa. All of this can sometimes make it hard to pick out details in the surroundings. Action cameras also sometimes overlay information on the video feed such as camera mode, recording time, video settings, etc., and although some of these can be helpful, generally the stock on-
be hard to mount to an aircraft because of their size and weight. Although some are streamlined, GoPro is notorious for making cameras that have a large, un- aerodynamic format that can be hard to deal with. I primarily fly FPV looking through my GoPro. It is annoying at times, but for me, the image is clear enough, the colors and lighting are fixable in the brightness and contrast settings in my goggles, and I have the added bonus of having a wide field-of-view from the GoPro. Some cameras strive at
camera for recording video is becoming popular, even on smaller aircraft. This is great because the best mounting angle for flying might not be the same for recording video of what you want on the ground. A two-camera setup is
helpful when flying with a gimbal because you would never know your aircraft’s orientation if you flew FPV through the gimbal camera. If you still want to check in on your recording camera to see if you’re getting the shot you want, you can even get a video switch that plugs into a spare auxiliary port in your receiver and allows you to toggle between video feeds. FPV flying is a fantastic
way to experience RC flight

being both good for FPV and great at recording, such as the FoxTech HorizonHD (
foxtechfpv.com) camera, which is easy to mount and fly, but if you’re really concerned about seeing the clearest image when flying and still recording the best possible video, and if your aircraft is big enough, just use both.
Using a fixed-board camera for FPV and an action
in a much more immersive way. Having a view that makes it easy and clear to see your surroundings when flying, and being able to take away great footage that you can share with your friends, is important to every FPV pilot. I hope this article has
helped open up your perspective about camera setups for your next build. Maybe I’ll see you around in the sky sometime!
