Eachine DVR03, mini test

Another mini test! Why mini? Because, you will see, it was not necessary to continue testing further with this DVR03. What is DVR03? It is a camera combo - video transmitter 5.8 GHz with alluring features, which also acts as a recorder. The promise is therefore to have a video feedback in real time and to be able to record the images in HD quality.

Tour of the owner

The DVR03 is an AIO (All In One) combo larger than its competitors. It weighs 7.61 grams on the scale with its Tiny Whoop connector cable, 8.08 grams with the Molex 2.0 cable extension. And 8.35 grams with a microSD memory card. Because yes, despite its Lilliputian size, the weight of a microSD card is not negligible. It measures 3 cm in width, 4 in height counting the antenna, and 3 cm in depth counting the objective and the antenna. It is therefore not compatible with the pedestals for combos intended for the Tiny Whoop. In any case, his weight would not allow him to be placed on board these aircraft. The same applies to brushed machines such as QX90, QX95, QC90, etc. He needs a more powerful device. The lens ensures a wide angle 120 ° FOV via a 520TVL sensor.

The 5.8 GHz transmission part

The camera is coupled to a 5.8 GHz video transmitter compatible with 72 channels! Friendly. The emitter can also choose the transmitter power: 25 mW (compatible with European regulations), 50 mW and 200 mW. As well as the 0 mW, which corresponds to zero emission. This makes it possible to make adjustments without interfering with the other transmitters in operation. This was already the case with the TX03 (see the test here for more complete explanations), a very similar combo since it was the first to offer 72 channels and 4 powers. The antenna is of the polarized type, with 4 lobes (RHCP). The power supply to the camera requires 3.2 to 5.5V. A LED is used to check the settings, it indicates alternately the frequency range, the frequency, and one or more "-" symbols to indicate the transmission power. A single button on the top allows you to manage these settings.

First try

If a memory card is inserted into the DVR03, recording starts automatically when it is turned on! Practical, and a stopwatch in red indicates the duration. But the result on the screen of a 5.8 GHz video receiver, is disappointing. Frames are very clearly missing, we are far from 25 or 30 frames per second. This results in a jerky video, with blurry effects. Can not drive properly under these conditions! At the back of the camera are 3 buttons, marked C1 to C3. Pressing the C2 stops recording. The image is instantaneously more fluid, the usual quality for camera combos - transmitter 5.8 GHz, and which allows to pilot in immersion. Pressing C2 restarts the recording. And the framerate slowed down again. Too bad, because the real-time video feedback function is still the most important of this accessory! Can we drive in a "cushy" way, as for example with an ultra-stabilized machine like the Mambo of Parrot? Yes. But then pépère from home pépère ...

And recorded videos?

They are stored in avi, in MJpeg format, in a resolution of 1280 x 720 pixels at 30 frames per second. Is the image beautiful? No. The compression is strong (the throughput is 16 Mbps), introducing a blur effect. There is a strong fringing effect throughout the image (not just on the edges), that is to say a halo often blue around the dark objects on a light background. There is a strong remanence that introduces a blur of motion. What's more, the image is blurry on the edges. Pfiou, that is not very engaging! Only the colors are pretty nice, with a respect of the red enough unusual to be mentioned. Note that the sound is recorded via a microphone. A long press on the C2 button allows access to menus, which can be in French. Long press C1 button to play the videos on the memory card, they are broadcast via the 5.8 GHz link.

But then ?

It was expected that this combo camera - video transmitter, which was hoped to be able both to transmit a real time image with very little latency to pilot in immersion, and to record the image on board to avoid parasites And the low resolution of videos shot with a ground recorder. But the promise is not kept. If it is used only as an FPV camera, the DVR03 works correctly. But its weight and its congestion are not justified, it is better to prefer a TX03 to him. If used with both FPV video feedback and recording, this video feedback is too mediocre to drive in immersion. Only then remains a third use, that of a 720p camera, without taking advantage of video feedback. The picture is not great, far from.

Fayee Smart Egg Wifi Review

This small multirotor is intended for indoor flights, and for beginner pilots. It is intended for use with a smartphone or a radio remote control (supplied). To facilitate the piloting, it is barded with sensors including an altimetric barometer to manage the height.

Special Beginners

To distinguish themselves from the competition, the conventional propeller shields are replaced by a structure that surrounds the aircraft. Is it effective? Hard to say before you tried! A camera is on board, a VGA model (0.3 megapixel) associated with a wifi video transmitter. The image is sent in real time to your smartphone. Do not plan to fly in immersion, the latency of the wifi is generally much too important for the control in FPV is possible. The Smart Egg Wifi from Fayee will be offered at a little more than 36 € at Banggood (with the port but without taxes), in white or in black.

Eachine X73S Review

Eachine's X73 had not left us an imperishable memory, much too fragile among other defects (see here). The X73S is the new version of this device, which proposes a radical change: brushed motors are replaced by brushless! It is 1103 to 10000KV driven by ESPs of 3.5A BLheli which drive quadruplical propellers, all driven by a Naze32 flight controller. The FPV camera is a 600TVL associated with a 5.8 GHz 25 mW and 32-channel video transmitter (compatibility with ImmersionRC Raceband is not indicated), and a dipole antenna.

And…

The 2.4 GHz radio receiver is either a DSMX, a FrSky or a Futaba. Note the DSMX, for compatibility with recent European Spektrum radios, Futaba (a format rarely used by nano multirotors) and the lack of compatibility with the Flysky AFHDS and AFHDS 2A protocols. The recommended battery is a 1S 450mAh 25C, not included in the box. Too bad that compatibility with a 2S battery is not assured. The data sheet indicates a take-off weight of 43 grams - which seems light, the battery is probably not counted in the weighing.

What do you think?

Difficult to erase the memory of the X73, especially as the protections of propellers seem very similar - they were brittle, from the first shocks, on the previous model. With brushless motors, so more power, we can fear damage if they have not been seriously reinforced. ESCs seem to be in the arms. In case of breakage, it is necessary to change the entire frame, including ESC. The fixation of the camera seems the same as that of the X73: it was disconnected regularly in case of shock. A nano multirotor of 10.5 cm of side with brushless motors, it is alluring ... but we ask to see! The X73S from Eachine will be offered from 93 € at Banggood (with the port but without taxes).

FPV-quadrocopters: description, features and reviews of the best models

Unmanned aerial vehicles, or quadrocopters are now used not only kinodela and paparazzi. Base models have become available to the average man in the street due to strong competition and market congestion. Cheap quadrocopters can be bought for less than $ 100, and a gadget with a good camera and an overview can be found in about a couple of hundred, while the really high-quality and more sophisticated models crossed the mark of $ 1,000. 

The complex and, therefore, expensive design allows you to adjust and reprogram almost all the basic functions to suit your needs, turning the drone in a truly stand-alone device that is able to make their own decisions and follow a particular character behavior in a given situation. 

Most fans of this kind of gadgets prefer models equipped with FPV (First Person View) function, ie the ability to see everything that happens in the first person. Moreover, the signal receiver can be anything: FPV-glasses, smartphone, laptop or desktop computer - it all depends on the particular model of the drone. 

The following will be presented to small surveys quadrocopters that contrast to the general public and experts in quality, independent work time and functionality, but somewhere simplicity and balance characteristics. Selection includes devices to perform different tasks and different budgets, so pick up something just for your needs can be without problems. 

UDI U818A 

One of the most popular (and for good reason) UAV models for beginners. The price tag starts at $ 50, so the line can be classified as "cheap quadrocopters". A check may vary depending on the bells and whistles drone, but suitable for a beginner is the simplest model without an extended functionality and unnecessary yet canopies. 

The first thing you have to read once bought quadrocopter - instruction. Once you learn the basic aspects of safety, you can begin to learn control drone. The only thing that is required at this stage of the beginner - is to try to prevent accidents that beset him at every step. 

The model has a solid set of benefits for its small price: chetyrёhpetelnaya frame protects the rotors from the collision, with the screws themselves are inexpensive (about $ 3 per set) and changed relatively easily and quickly.
