Eachine Flyingfrog Q90 Review

This flying frog looks like a toy, but it displays pretty seductive features! The fully enclosed aircraft is based on a F3 flight controller, which drives brushed 8520 engines of 14000KV (slightly less than the "fast" models of Micro Motor Warehouse) for 5.5 cm propellers fed with 2S, by a Lipo 7.4V of 350 mAh in 30C with a plug Molex 2.0. The weight of the Flyingfrog Q90 without battery but with protections of propellers is 41 grams. We can expect a good power / weight ratio! The 2.4 GHz radio receiver is either DSM2, FrSky or Flysky.

And…

On the video side, the camera is a 1000TVL with a FOV of 110 ° associated with a transmitter 5.8 GHz of 40 channels and 200 mW (this is more than allowed by the European regulation). The dimensions are 8.8 x 8.8 x 4 cm for a diagonal of motor motor of 9.8 cm. The device is supplied with removable propellers. Based on technical data, it is a small machine that can prove to be nice to fly indoor, with which one can also hope to venture outdoors. The manufacturer ensures that the device is wind resistant, probably by putting forward its engines and its fairing. This will be checked, of course! Eachine Flyingfrog Q90 is offered from 66 € at Banggood (with the port but without taxes).

Robots on the remote control, Interactive toys for boys

The world of toys is not standing still. And if even twenty years ago, children dreamed about dolls and realistic typewriters, then malyshni generation gadgets have conquered the robots on the remote control. It should of course be noted that they are addicted to not only children but also adults - everything depends on the proposed functional, yet manufacturers are increasingly oriented to young audiences. What is he - a robot on the radio, and whether it can be something more than just a toy? Could he not only entertain, but also something to teach the child? 

Automation of modern life 

Let's start with the fact that now more and more space in human life belongs to the automated devices. Today, few wipes hand, if there is a washing machine, and whether you'll be unlikely to rely on sunrise or cock cries to wake up in the morning, when it is possible to have an alarm clock. 

All our domestic gadgets - these are the same robots, just another level of complexity. The interactive robot has come already, and medicine (as an assistant in the operations) and in industry (construction machinery carried programmed for a specific task of devices), and in the defense industry (autonomous reconnaissance easily gather the information you need), what to speak of the various robot assistant who so actively promotes Japan - the world leader on the issue of robotics. You can not be afraid of these innovations, because progress is inevitable, and robots - an integral part of it. So, give your technophobe and still think about whether a robot on the remote control will be able to become the boys really terrific gift. 

Guided and self-guided robots 

Let's move on to the classification of robots. Let's start with the fact that they are managed and self-managed, in other words, subject only to the commands or make decisions for yourself. Most often the last type - a robot on the remote with the camera that captures the situation around so that artificial intelligence could make a decision. For example, appeared on the way an obstacle - controlled robot will stop in front of him, waiting for commands from the remote, while the self-governing, analyzing the situation and find a way to work around it. 

Naturally, self-managed robots cost more - because they are difficult in themselves, yet the process of choosing an action plan without any inclusion of human mesmerizing.

Vantac Q100 Review

The Chinese manufacturer Kingkong is master in the art of copying machines. But for once, it is he who gets copied! Or maybe it's an exchange of good practices? Its model Q100 (see here) is also called Q100 at Vantac. What are the differences ? The Vantac version is based on a camera combo - video transmitter of 700TVL instead of 600TVL for the Kingkong version. The Vantac version is exclusively available with a Frsky receiver, while the Kingkong is available either with a DSM2 receiver, Futaba receiver or without a receiver.

So ?

The choice simply depends on the radio control you have: Vantac for a Frsky, Kingkong for a DSM2 or a Futaba. What about a Flysky? Either you choose a Kingkong version without receiver and you install yours, or you turn to this version on eBay (note that I do not know if the seller is to recommend). The Vantac Q100 is available on Banggood for around 76 € (with port but without taxes), with a red or yellow fairing.

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).
