Basic FPV setup on a plane
A small and light-weight camera is mounted to the aircraft in order to have the FPV (First-Person-View) flight experince. This introduce a new experience in pilot control; in such a way that you are in the cockpit of the aircraft. The live aerial feed of the FPV camera is transmitted to the ground monitoring station. An AV transmitter which is connected to the FPV camera, sends the video signal from the FPV camera to the ground station. An AV receiver at the ground station will receive the video signal and the live aerial feed can be viewed from a monitor. To enhanced the system, implement a DVR recorder to record the video; in this case the AV receiver has a built-in DVR. To enhance the FPV experience, an OSD (On Screen Display) board can be introduced to the system. The OSD will overlay the aerial view with various parameters; such as compass / GPS heading, altitude, airspeed, distance from HOME position, travelled distance, current draws, power consumption, battery voltage, etc.
Please be aware that the antenna of both the transmitter and the receiver must be connected properly before powering up the system. DO NOT swap the antenna; use proper spec antenna for transmitter and receiver respectively. Make sure the frequency of the FPV system does not conflict with your radio transmitter system to minimize noise.
The ground monitoring station consists of the monitor, AV receiver, and a Li-Po batt as the power supply. These devices are mounted on a standard camera tripod for your convenience. FPV goggles can be used to substitute the monitor.
- Live Aerial View can be monitored from ground. You are able to see what you are recording.
Provide a real pilot control, FPV (First Person View). This enables you to pilot your aircraft at further distance and height beyond you viewing capability from the ground (providing the AV transmitter and receiver is high-power spec and LRS (Long Range System) for the radio transmitter is being implemented).
- The Aerial video is being recorded in a low SD quality; unless FULL HD camera, such as GoPro HERO camera is implemented as a substitute to the FPV camera and the GoPro HERO camera functions as the FPV camera and recording camera (using memory card in the camera) simultaneously.

Design review :
- Flaperons mixing is implemented, along with 3 position switch for take-off (overhead hand-launch), level flight, and landing.
- Wing loading is sufficient for carrying the FPV camera, the AV Transmitter and the extra Li-Po Batt for the transmitter.
- Recording Aerial feed by using the built-in DVR in the AV receiver of the ground station.
