Basic FPV Setup Option for DLE-TR01


There are 3 options for basic FPV setup which is possible for the design platform DLE-TR01.

FPV equipment and devices are obtained from Aerofly logo

FPV Setup with GoPro Camera as the recording camera.

 

The first FPV setup is to implement GoPro Camera as the recording aerial view camera. An EPP foam block is cut and shaped to fit in the aircraft’s nose and a GoPro flat adhesive mount is mounted and embedded to the EPP foam block. The GoPro camera is mounted to the flat adhesive mount by using the skeleton housing. This skeleton housing is heavy, but provide better protection compared to the frame (please refer to the GoPro accessories).

Note that the EPP foam block is shaped to fit the aircraft’s nose with little/no slip to fasten the camera properly during flight. Double-sided tape or Velcro implementation will secure and fasten the camera even better. The cockpit’s lid is required to be cut and adjusted to the length by which the lid can be closed properly.

GoPro 05 Rev0

Pros :

  • Aerial View is being recorded in high quality and Full HD.

 

Cons:

  • There is no ground monitoring with live aerial view from the camera. You are unable to know what you are recording, until you have landed and view the recordings from the camera’s memory card.

FPV Setup with FPV Camera and ground monitoring station.

 

The second option is to mount FPV camera to 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 enhance the system, implement a DVR recorder to record the video; in this case the AV receiver has a built-in DVR. For more advance 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 operational convenience. FPV goggles can be used to substitute the monitor (not recommended for the first FPV flight).

FPV 01 Rev0

Pros:

  • Live Aerial View can be monitored from ground. You are able to see what you are recording.
  • Lighter payload compared to the GoPro setup.
  • 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).

 

 

Cons:

  • The Aerial video is being recorded in a low SD quality.

FPV Setup with GoPro camera as the recording and FPV Camera simultaneously.

 

 

The third option is to mount the GoPro camera, functioning as the recording camera, as well as the FPV camera simultaneously. The GoPro camera is connected to the AV transmitter through a 90° USB to AV conversion cable. By using this setup, the live video signal is transmitted to the ground station, and the GoPro camera still able to record normally to the installed memory card. Make sure that the battery of the GoPro camera is fully charged to prevent the camera from turning off while piloting. This occurs because the AV transmitter is no longer supplying the power to the camera; only the video signal cable is connected.

In this setup, GoPro “The Frame” is being implemented instead of the skeleton housing in order to reduce weight. To further protect the camera’s lens, it is recommended to include the GoPro protective lens.

FPV GoPro 01

Some minor modification is required to be done to the frame in order to install the USB to AV conversion cable properly. The side opening of the frame is required to be enlarged to the dimension which will allow the cable header to be installed.

FPV GoPro 05

Finally, the camera is mounted to the aircraft’s cockpit and plug in the USB to AV conversion cable to the AV transmitter.

 

 

FPV GoPro 06

 

 

Pros : 

  • The best FPV experience and obtaining high quality recording with a moderate payload.

 

 

Cons :

  • The moderate amount of A.U.W (All Up Weight) reduces the battery efficiency and slight maneuverability, as well as the glide ratio.
