FPV (FIRST PERSON VIEW) is a method used to control RC aircrafts from the  pilot point of view. The vehicle is driven remotely from a first-person perspective via an onboard camera fed wirelessly a video monitor,  a tablet  or  a  mobile  phone.  A basic FPV system consists of a camera and a video transmitter on the aircraft, with a video receiver on the ground. FPV aircraft are frequently used for aerial photography and videography. Many lightweight high-definition cameras  can be carried by Quads  and they are also able to connect via Wi-Fi. Go-Pro and Walkera Ilook are two examples. An upmarket aircraft can also carry a gimbaled camera and GPS navigation to create a truly immersive first-person experience, as if the pilot was really sitting in the cockpit of the RC aircraft. For that, its possible to use specific monitors (Ex.:Boscan) or immersion glasses like FatShark or Skyzone, among others. Using glasses, low cost 320×240 resolution goggles are not recommended because the higher resolution 640×480 or SVGA goggles provide a much better and secure flying experience.

VIDEO DOWNLINK sets for RC aircrafts are current available in the market. There are revolutionary Full HD digital video downlink equipment extremely powerful  and packed into small and lightweight cases. Some of them offer 1920 x 1080 (30fps) video data transmission from up to 1.0 km. Of course, there are less sophisticated systems that offer lower resolution video, for smaller distances at more affordable prices. It includes some small quads as Hubsan X4 H107D and small cameras as Walkera TX 5885 built in with a 5.8 GHz video transmitter. When controlling an aircraft with a 2.4GHz RC transmitter, the best option will be using a 5.8GHz for video downlink. This way, it’s possible to avoid interference between both systems.
