This is a good device, but it is needed for good quality video shooting, so its price is huge over $ 1000. For a hobby this is very expensive.

When you do not have a FPV model .........

This toy simulates a FPV aircraft. Her device does not allow you to fully control the model, the flight time is very short. The model is small, the video from its side will be terrible, the small models are not stable in the air.

Buddy, these antenna parameters are calculated for 2442 MHz frequency, for 5200 MHz they do not fit.

In the design of the antenna there is a closed connection of the elements, it should not deviate from this, since this changes the parameters of the antenna.

The engine on a flying wing is usually put from behind and is pushing. This makes it possible to get the correct center of gravity of the model. The center of gravity is regulated by the position of the battery. It also allows for the model to exclude the entry into the frame of the camera, the propeller of the propulsion system.

This is a high-speed model. It is designed for a fast flight. In front there is a running battery. It is connected via wires and a special connector with a speed regulator that controls the engine in accordance with the signal from the radio receiver with the antenna. A little behind the receiver is likely stabilization systems with a GPS module.

What exactly interests you in this?

What material can make the connection between the reflector and a vibrator?

All lovers of this hobby are looking forward to drawing, this outstanding antenna.

The video is not of the best quality Article on the construction, though in Russian.

My friend, the model in your photo is a wing made in the factory, it is on sale for a bangood. I did not see any drawings for self-construction.

This wing is sharpened with minimal reflection of the radio beam, the rest is not very. Under this link, the drawing is a small wing with a simple manufacture.

Friend of the wing about which you ask in the topic of homemade and not better quality. Here are some drawings for self-production. http://rcplans.ru/download.php?f=Vzhik.zip http://www.rcgroups.com/forums/showthread.php?t=1000670 http://www.jivaro-models.org/pyth700/page_pyth_700.html http://aviahobby.at.ua/load/chertezhi/baklan/1-1-0-166 http://rcplans.ru/download.php?f=zagi.zip

I cut a wing from a penoplex with a gravitational foam cutter built using video kompmen1, the cutting is smooth and correct, which was not possible to achieve by hand. The wing profiles were built and printed in the program Profili2 , only it was paid.

Thank you very much! But this is a gift not only for me, but for all fans of FPV.

This is a very popular and interesting wing! These are the main parameters: Specs(astro/blaze): Length：29.1in(740mm) Wing Span：31.9in / 31.1in(810 / 790mm) Wing Area：1.61 / 1.53ft²(15 / 14.2dm²) Flying Weight: 21oz(650g) Pusher: 2826 2350kv Brushless Outrunner ESC: 30A Servo: 9g x 2 ZETA FX-61 This is a link to the manual from the manufacturer: http://www.newzeta.com/pdf/3.pdf

Admin, could you explain the values in the graph in more detail? By the way, the transmitter was just an Vee antenna.

Hello friends! I with my friend Andrey managed to test the antenna made according to the drawings developed by the respected ADMIN. The antenna showed itself with the best hand, the video was transmitted from a carrier located at an altitude of 2 kilometers, at a frequency of 1160 MHz channel 6.Transmitter with power of 1 watt. The reception was on the Chinese 12 channel receiver to which the BILOOP antenna is connected by 20 cm cable. The transmitter is located 1.5 meters from the ground. The video was taken immediately from the distance of 55 kilometers and the plane lay down on the course with removal. At a distance of 104 kilometers had to return. Reception all the time was of good quality, the image began to deteriorate with a decrease of less than 1.5 km, interfered with the terrain. Conclusion: the antenna is excellent for FPV hobby, easy to manufacture, works without tuning with the help of instruments. Thank you very much author ADMIN. http://forum.rcdesign.ru/f90/thread142729-337.html

And if the vibrator is also made in the form of a cone. An even more flatness diagram will be?

Do I get it right? Is the antenna pattern with the cone much better than antennas with counterweights?

And how do the dimensions of the antenna elements change with this design? Or the sizes can be used from the calculator above specified? Thanks for the help!

Hello friends! I built the antenna according to calculations kindly provided by the respected ADMIN. For bending the wire, I made a pattern of metal, with the hands of the wire on the outer edge of the template, then pressing the pliers around the inner edge with pliers. Soldered the two rings through the half-grooved edges. Soldered strips, then the whole construction on the reflector. The rest can be seen in the photo.

Sorry, this should work link
