FPV - First Person View - IndroductionFPV is a relatively new branch of our hobby in which a video is mounted on the remote controlled plane. The video image is transmitted to the ground. On the ground the pilot looks at a screen or wears video-goggles. The pilot has the feeling he is sitting the the plane, hence the name: First Person View.
This is footage of some of my recent flights, this is what I see in my video goggles...
In addition to the a video camera, transmitter and receiver these other components are often used:
A head-tracker detects the movents of the pilot's head. Combined with a pan/tilt system, the camera on the plane mirrors the pilot's head movents. This way the pilot can look around.
OSD stands for On-Screen-Display. It is inserted between the camera and video transmitter and adds information to the screen. OSD's connected to a GPS receiver can display basic information like altitude and groundspeed but can often also calculate the position relative to the pilot or other points-of-interest. Some OSD's have a "return-home" functionality that can autonomiously return the plane to the pilot in case of a technical problem.
A Diversity Receiver consists of multiple receivers that are often equiped with different antennas. The system automatically selects the receiver that generates the best image.
A Recorder, it is great to have footage of your flights. One option is to use a laptop or a DVD recorder. A better option is to use a camcorder with an analog video input or another dedicated device.
1st FPV plane - EasyGliderMy first FPV plane was a modified EasyGlider, the same platform I used for aerial photography before. Part of the nose was cut away and another flat surface was created above the wings; plenty of room for all the components. The motor was placed on a pylon behind the wings so that prop does not obstruct the camera view.
Due to the pylon mounted motor, the plane has a tendency to plunge when power is suddeny applied. While flying low, and especially for FPV, this tendency is a nuisance.
2nd FPV plane - EasyStarMy second FPV plane is an EasyStar, a very popular choice for FPV. It provides plenty of room and is designed to have a motor behind the wing. It also has a light tendency to plunge but much less than the EasyGlider.
Later I decided to install the camera on the original canopy resulting in a cleaner and more aerodynamic installation.
New platform - Mikrokopter
GroundstationThe groundstation consists of two video receivers equiped with different antenna's. The Oracle Divercity Receiver automatically selects the receiver that generates the best image. The Canon MV960 records the received image.
