Testing the RunCam 3 by RCModelReviews

Tuesday 28th February 2017 8:41 AM


I rarely echo tests that I did not realize myself, but this review of RCModelReviews is very interesting: it concerns the RunCam 3 camera, which espouses the cube format of the GoPro Hero Session. Bruce Simpson, in preview, reviews all the positives and negatives with his delicious New Zealand accent, a nice work as for each of his videos.


What to remember


The positive points ? Good pricing, videos with a satisfactory dive, true-to-life colors and a WDR Dynamic Range (a kind of HDR), a GoPro Session format suitable for mini multi-rotors, a battery that offers 1 hour of d 'Autonomy, a solid lens protection in Gorilla glass. The negative points ? The camera "swallows" the microSD memory card if it is inserted incorrectly (and it is not easy to open), there is no (yet) application for smartphone, the sensitivity of the microphone is not Adjustable, and the battery is not removable. The entire test is to be found in Bruce Simpson's video ...

The drones regulations in the world?

Tuesday 28th February 2017 8:02 AM


If you plan on going on a multirotor vacation in suitcases, it is better to have a good idea of the regulations that await you upon arrival. It would be a shame to finish at the post and with a salted fine ... We had already presented Drone Law In ... (see here), but the data is not satisfactory. Those concerning France are not exploitable. It is preferable to turn to the Global Drone Regulations Database, an impressive database that documents the regulations of most countries on the planet.


The test ?


It is obviously to check what is indicated for France. The data are correct, enough for a foreign pilot to know what to fly to in France. Very good first impression, then. The same test with Belgium confirms the first impression, the data are accurate. What about Cuba? Drones are not allowed, there is confiscation at the customs. The same goes for Morocco. In Iceland, on the other hand, you can do almost anything you want. For some countries, the data are fragmented, as for Sweden, where the authorization to fly is mentioned at the same time as the complete ban adopted in October 2016 (see here). The basis should evolve rapidly, it is built on the principle of sharing information.


Who is behind the site?


Global Drone Regulations Database is an initiative of UAViators, a network specializing in drones for humanitarian actions. The Foundation has been in existence since 2014, supported by the Swiss De-mining Foundation (FSD), which has been enriched by several contributors. Parrot is one of them! There is still a sharper separation between recreational use and commercial activities, but the database appears to be the most comprehensive that can be found. The Global Drone Regulations Database site can be found here.

DJI Matrix 200, for professional missions

Monday 27th February 2017 2:02 PM


At the Mobile World Congress 2017 in Barcelona, DJI presented the Matrix 200, a drone destined to carry out professional missions. An impressive machine designed to accommodate equipment to conduct air inspections and data collection, including in harsh environments and when the weather is not cooperating. DJI for critical infrastructure inspections (bridges, telecommunication towers), inspections of energy-related installations (high voltage lines, wind turbines, oil platforms), site mapping and public safety ( Search & Rescue services, firefighters). Its dimensions? 71.6 x 22 x 23.6 cm for a weight of 3.80 kilos.


The equipment


The M200 is foldable for ease of transport and IP43 protection, ie protected against dust of more than 1 mm in diameter and against rainwater up to 60 ° from vertical. DJI has equipped it with more than 20 sensors for a redundancy of the components which makes it possible to improve the reliability, with double IMU, altimetric barometers, an electronic compass, a GPS system. Because it is capable of evolving in the presence of obstacles, it is equipped with two optical systems at the front and under the device, supplemented by an infrared sensor capable of detecting obstacles above it - an important tool for Facilitate flights under bridges, for example. It has two batteries that power the device in sequence for up to 38 minutes depending on the on-board load and battery type (a 95 Wh and a 174 Wh). At the front is a camera, as on the Inspire 2, which allows the pilot to fly in immersion. The M200 can be controlled by a driver, and its cameras operated by a camera equipped with a second radio control.


Inspection tools


"His" cameras? In addition to the front camera, the M200 can be equipped with an entry-level X4S camera, a 4x3 microphone X5S camera, a Z30 with mechanical zoom, or an XT that allows thermal imaging in conjunction with FLIR . The standard M200 is designed to carry a single camera, with a nacelle attachment on the underside of the camera. It is complemented by two other versions! The M210 is capable of accommodating two parallel nacelles under the aircraft, or a nacelle above. It can also be equipped with additional sensors and accessories developed by third-party manufacturers. Finally, the M210 RTK version is equipped with an RTK (Real Time Kinematic) module, which improves the satellite positioning to achieve a theoretical accuracy of the order of one centimeter.


Additional tools


All versions of the M200 are equipped with the AirSense DJI function, which is based on an ADS-B box. This system for receiving transponder signals makes it possible to obtain, in real time, the position, the altitude and the speed of apparatuses which evolve in the airspace. What to consider more serenely flights in an environment occupied by inhabited devices! Note that this is ADS-B reception, no transmission. The M200 is compatible with DJI GO 4 smartphone and tablet software, but it also takes advantage of the DJI Pilot application for industrial applications and DJI GS GO (GroundStation) to plan missions in a simple way. This is at least the promise of DJI, which also offers SDKs (development kits) for developers to realize their own software tools.




DJI Pilot can work with DJI FlightHub, a real-time DJI data sharing tool to facilitate data sharing between field teams and management centers. This system allows all of them to visualize in real time the position of the aircraft in flight, their trajectory, their state, the video flow, to intervene on the flight plans and to pilot the cameras on board. For real-time image transmission up to a resolution of 1920 x 1080 pixels, the M200 relies on Lightbridge 2 with a range of up to 7 kilometers (depending on country and regulation).

Tiny Whoop boosted: The BeeBrain and Insane engines

Wednesday 15th February 2017 12:08 PM


You might have read the test of Insane Motors from Micro Motor Warehouse installed on a Tiny Whoop. They give a nice fishing machine, but it trembles on all sides, making the flight very unpleasant. In the absence of the possibility of adjustments of the flight control, the solution is that is necessary ... it is to change flight controller! In the end, we get what? A nano machine to fly indoors with its protections of propellers, but powerful enough to fly also outdoors, with a little aerobatics ... The whole of the manipulation is very simple.


The proof ?


It's because I got there - and yet I'm not good at it. Just two soldering points is the most complicated step. Dsc_0009-1200I have opted for the NewBeeDrone BeeBrain v.1, a flight controller that measures pile-hair the same size as the Blade Inductrix. However, it relies on a Naze32 type electronics and Betaflight firmware rather than proprietary and non-adjustable Horizon Hobby software. It is proposed with an integrated receiver compatible with DMSX radios (Spektrum) or FrSky radios (like the Taranis). The video of some flights and a proposal of list of components can be found at the end of this post.


The base ?


Dsc_0114-1200The required to mount a Tiny Whoop Survived, is simply basic chassis of Inductrix. There are many other versions, plastic, 3D printing, aluminum ... No matter which one you choose, but the more the chassis is light the better it is. Shock resistance is not a fundamental criterion: all are repaired a number of times, then they must be changed when they are in too bad a condition. You can of course recycle an Inductrix from Horizon Hobby to give it a second life. Or an E10 from Eachine, to offer him a real life! That is the solution I have chosen. Simply adjust this step by step by removing the steps you do not need, especially by going directly to step 6 if you are starting from a bare chassis.

DJI Mavic Propeller Cage

Tuesday 14th February 2017 9:22 AM


Forget the simple propeller guards for the Mavic Pro, here are the Propellers Cages. These are grids that completely cover the propellers, for more effective protection. It will not avoid putting your fingers in it, nor to get a good lock of hair, but this accessory limits all the same well risks.


That said…


This makes it possible to fly in the presence of obstacles and to be able to touch them without the incident interrupting the flight. And in the audience? This reduces the risk, but be very careful about what the regulations say about it. The Propellers Cages for the Mavic Pro are available on the site of DJI to 179 € the 4 pieces, delivered to 3 pairs of propellers.

Cheerson Tiny CX-95S Review

Tuesday 14th February 2017 9:07 AM


This is at the same time a competitor of the Horizon Hobby Blade Inductrix FPV, Eachine E010S and the Makerfire Micro FPV. What sets it apart from its 3 competitors? This is not the look, it is similar to that of the Tiny Whoop with its propellers imprisoned in Duct type protections. These are its engines, brushed 7x20mm - those of its competitors are 6x15mm. The size and weight of the machine are similar, however, according to the data sheet: 8 cm diagonal and 4 cm propellers, for 43 grams on the balance with its 1S 400 mAh battery. The flight controller is an F3, probably under Cleanflight and flashable in Betaflight. There is no choice for the radio receiver: it is a DSM. There is no indication of the 5.8 GHz camera / video transmitter on board.




It's a seductive little machine, but we'll have to wait for tests to see if it's keeping its promises. The Tiny CX-95S by Cheerson will be offered as a self-assembly kit - attention, a bit of welding seems necessary - for a little more than 60 € at Banggood (with the port but without taxes), with a blue and orange fairing Or green. Note that there is also a version with a return video wifi, a little cheaper, and provided with a radio control, always at Banggood. Beware, the real time video feedback is essential to have fun really with this type of machine, and wifi does not allow it.

Eachine Flyingfrog Q90 Review

Monday 13th February 2017 11:15 AM


This flying frog looks like a toy, but it displays pretty seductive features! The aircraft is fully air-conditioned and rests on an F3 flight controller, which drives brushed 8520 engines of 14000KV (slightly less than the Micro Motor Warehouse fast models) 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.




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).

Educational toys for children 4-5 years: designers, sets scene for games, musical toys

Wednesday 8th February 2017 4:19 PM


Commodity abundance, including in children's products stores, sometimes baffling. Everything is bright and attractive! But the whole store can not buy, for the child wants to choose something really right: interesting and useful. All these criteria meet the educational toys for children 4-5 years.


Age Feature


Before we talk about what the children like to play in the 4-5 years, it is important to understand what features are typical for this age. Toddlers still pay attention to the bright objects, but their interests are becoming increasingly compartmentalized. In each of them there are their hobbies, favorite cartoons and fairy tales, characters and heroes. In addition, it is already possible to identify and priority direction for future development: is where parents should make their efforts. Maybe it's the music? Dancing? Painting? Or swimming? Or soccer?


The most useful educational toys for children 4-5 years


The perfect toy - is the one that teaches a child something new, not necessarily read or read the correct move, to play some scenes with their favorite characters is also important. The development comes at a time on several fronts: intellectual, creative, emotional and social. The child learns to dream, to communicate, to find a way out of different game situations. It can not be taught in the classroom. It is known only in the game.


Young architect


If your child is interested in creating figures from the designer, consider yourself lucky. Catching up with tiny Circuits, doshkolenok develops his fine motor skills. Thinking about how to create particles from disparate whole, develops synthetic and analytical thinking function. In the future, this hobby will help him to learn mathematics quickly, deal with writing easier. In addition, the ability to collect figures on the instructions trains skill patterned repetition, and the ability to come up with something of my own creativity sells.


Children's constructor can be anything: wood, metal, plastic or magnetic. Each variety has its own characteristics, but the above properties are inherent in all of them. Of special note is the block type designer "Lego". The kits may include from tens to thousands of parts. At the same time they are universal: a pair of ships, for example, can build a castle, and out of the car - a spaceship. The number of assembly options for such designer virtually unlimited. It is a whole world! In addition, Lego kits include characters: humans, animals, household items or weapons for them.


And it already gives the child the opportunity to use them for building plot, role-playing games. Peoples are divided into good and bad, perform some action, live their lives. Attentive parents watch the game of your baby, can make conclusions about what is going on in his mind, what he is interested in what is going through. Maybe this will help them to direct the child's development in a right direction.

The history of the tabla is unknown. Perhaps the features of the game on this instrument, and the details of its design have developed based on a combination of Indian, Persian, and other traditions.


The membrane of both parts of the tabla is made of leather and covered with a special compound that affects the timbre. This coating creates a distinctive sound expressive drawing tool, makes it flexible in building, dynamic and technically. -

Multifaceted sitar


Perhaps the most well-known Indian stringed musical instrument - a sitar, or sitar. He belongs to the lute, and is able to create a unique sound palette, inaccessible to many similar tools.


At sitar seven main strings and 11 to 13 more or resonator. During the performance of a musician uses the basic strings, their sound respond the rest. As a result, the melody becomes more profound and multifaceted.


A sitar can be compared with the whole orchestra in this regard. To play on this stringed plucked instruments use a special mediator - mizrab. In form it resembles a long claw, and fastened on his right index finger. The main feature of the sitar - the resonator is made of pear-shaped pumpkin. Often, a tool is provided and an additional resonator, which is attached to the top of the neck. Structurally similar to the sitar is esraj, musical instrument with twenty strings.

Eachine Falcon 120, the test

Monday 23rd January 2017 11:35 AM


It is a very small racer in X, with brushless engines, which can fly indoors ... but by proceeding to a home-destroying session. More seriously, it is a machine intended for outdoor flights, a small perfect car for nervous flights without the need for vast spaces. Note that this device was given to us by the Banggood shop. As usual, tell us if you think the practice has influenced our judgment.


Tour of the owner


The Falcon 120 deserves its name, it measures 12 cm diagonal of motor motor. It is made of a main carbon plate drawn in X, with a thickness of 2 millimeters. Under this plate is glued a thickness of foam. The central block has been thought to be compact, it is stackable, or "stackable" in English. It is made of 3 floors. The first is an ESC 4 in 1, a Racerstar RS20A model which as shown offers 4 ESC of 20A compatible in 2S, 3S and 4S, BLheli_S, Oneshot42, Multishot, DShot600. The top floor is the flight controller, a SP Racing F3 model on the Falcon 120 that I tested. The last stage is a carbon plate on which the camera is fixed, with the help of a hinge designed to tilt it. The camera is a 700TVL model with an angle of 127 °. Under the plate is housed the video transmitter, featuring a RP-SMA angled connector and a short base mushroom antenna. It is a transmitter with a power of 200 mW, so it is too powerful for French regulation. It transmits over 40 channels, including the ImmersionRC Raceband.


Continuation of tour


On the plate, on the outside, is the AFHDS 2A 2.4 GHz radio receiver for a Flysky radio control in the RTF version of the Falcon 120. The floors are held by metallic red aluminum spacers. At the rear of the machine is a bar of 6 LEDs centered around a buzzer. Under the device comes an XT60 plug for the battery. Which is to place under the device, without nacelle, with a scratch Velcro. The engines are Racerstar BR1306 to 3500KV delivered with 3-inch quadrilateral propellers (3030-4). The battery supplied with the Falcon 120 is a Lipo 3S 11.1V 850 mAh, with an XT60 plug. The weight of the Falcon 120, without its battery, is 149.32 grams. The supplied battery adds 83.11 grams. Or 232.5 grams in order of flight.


Before taking off


As always, it is prudent to go check the parameters of the device, taking the precaution to remove the propellers. A microUSB connector is located on the back right side of the center block. It is located just in front of the axis of an engine, which makes the insertion of a USB cable a bit difficult. The firmware of the flight controller is Betaflight, version 3.0.1. All settings were made at the factory: PIDs, spleens, channels, etc. All that remains is to choose the arming method and the switch for the choice of the flight modes. The Failsafe must also be adjusted. It is quite easy, on the side of the radio control, a Eachine i6 (a Flysky FS-i6), since the protocol is the AFHDS 2A which supports the Failsafe.


First take-off


It happens in direct sight flight, as usual. The behavior of the Falcon 120 in Angle (stabilized) mode is very bright, almost too much for novice pilots. But we do it quickly. The machine is generally stable, however there are some oscillations, probably PIDs which can be improved. In Horizon mode, the angle grip is fast, allowing barrels and looping in a pocket handkerchief. Visual flight is the opportunity to adjust the video frequency. The principle is simple, a button on the video transmitter, not super simple access, allows to pass the 40 channels of the 5.8 GHz sequentially. It is a bit painful, especially since there is no visual indicator of the frequency and band chosen.

Eachine Chaser88 Review

Friday 20th January 2017 4:10 PM


The Chaser88 is a 12 cm diagonal motor engine, barely bigger than the innumerable brushed racers from Eachine. But it stands out with brushless motors, from 1103 to 10 000 KV equipped with 2-inch propellers, the 2030, powered by a 4x6A ESP 4 in 1 Blade-S compatible 1S and 2S (and Dshot600). The whole is orchestrated by a flight controller F3 Mini under Betaflight 1.3.1. The FPV part is provided by a camera combo and video transmitter which looks very much like a Eachine EF-01 without its case.




The camera is an 800TVL with an angle of 150 ° protected by a plastic arch, combined with a 5.8 GHz transmitter of 40 channels (including the ImmersionRC Racenband) and a power of 25 mW. The unit is supplied without a battery. You need a Lipo 1S or a 2S with an XT30 plug, knowing that Eachine recommends a Lipo 2S of 450 mAh and 30C. The bonuses? A LED at the back and a buzzer ... The weight? 67 grams without the battery, about 90 grams with. It will be necessary to add a radio receiver to complete the machine and take off. The Eachine Chaser88 will be offered at just over € 115 at Banggood (with the port, without taxes).


Additionally, if you happen need to purchase some rc quad parts, you can choose Banggood, which is one of the wholesale platform to provide affordable prices, such as cc3d revolution flight controller, rc battery checker, etc.

Helicomicro Cup Indoor, January 22nd!

Thursday 5th January 2017 11:45 AM


Because the winter is still set for a while, and because it is itching to see pilots compete in the circuits, we have prepared an indoor event in the Paris region by the end of January 2017. It will be the Helicomicro Cup, It will happen in a volume of 40 x 20 x 8 meters which will host a double circuit for two categories of multirotors, those with brushed motors and those with brushless motorization.


The two categories?


The brushed multirotors will have to remain under the 120 mm diagonal of motor motor, and under the 80 grams in order of flight. The battery should be of 2S max, the video transmitter of the 25 mW max as required by the regulations and compatible Raceband to facilitate the flights to several. The brushless multirotors must not exceed 140 mm diagonal of motor motor, 220 grams in order of flight, a battery 4S max, propellers of 3 inches max, a transmitter of 25 mW and compatible Raceband. The races will be timed with Team BlackSheep's TBS Event Tracker.


Or ? When?


The Helicomicro Cup will be held in the Pierre et Marie Curie gymnasium in Meudon, near Paris. The circuits offer you some surprises! To keep up with the shock, you can count on Pizza Bell. It will be January 22, 2017 from 9:30 am to 6 pm. For who ? For all those who want to compete with other drivers, whether with nano machines like Tiny Whoop and their derivatives, Nano Racers, or much more frosted brushless devices that require sharp steering. The registration fee per category is set at € 10. Registration will soon be open on Rotormatch, here for brushed machines, there for brushless devices. The public is welcome, without prior registration!

Eachine X73S Review

Tuesday 3rd January 2017 3:08 PM


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.




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).

Children's electric vehicles - their types and key features

Tuesday 3rd January 2017 2:54 PM


So, you have decided to buy a children's electric. With all the richness of choice, it is necessary to determine the characteristics, it is suitable for your child. The main characteristics, different models of children's electric cars are their dimensions, weight, height and power. As a rule, all current models of these toys, if you buy them from a trusted seller with a warranty and a certificate for the goods, made of quality materials, have no sharp edges and are safe enough. However, buying children's electric vehicle "for growth" should think about additional options. Let us each individually. Electric cars for kids on the remote control.


Machines on the remote control several kinds: for children from 1 year to 3 years, and for the older kids from 3 to 8 years. From the aisles of 20-30 m from the child, it is permissible distance of the remote, you can not only control the speed of movement of your child, but also to participate in the commission of maneuvers. The main difference - the size. Models for adult children is higher, heavier and, consequently, longer. Have a shift lever, which is usually three: two forward speeds with different speed indicator and reverse gear. for the smallest models have one speed.


On the children's electric cars on the remote account for only 15% of the total number of models available on the market. In addition, this option is available only in jeeps and cars, other models of children's electric vehicles (ATVs, tractors, motorcycles) are not equipped with remote controls. Electric, whether it is a model for large or very young children, is a means of transport capable of speeds from 3 to 12 km / h. Child driving a similar technique may be tired, distracted or just lose control. Therefore, as in this car, he and his companion had better be strapped the seat belt. If your young driver rides over rough terrain, it is not superfluous to the helmet and a powerful bumper, to mitigate the effects of possible frontal collision.


The heart of any electric car - its battery. From its power depends on many things, for example, while the electric vehicle in stand-alone mode, the speed and the ability to move through the sand and gravel. Note that there are models as a single battery or dual. battery marking is defined by two parameters: voltage and capacity. The most important - first, it is responsible for the speed that children's electric car is capable of. Unfortunately, the capacity of the battery is not connected with the working time of children's electric car, as there are a number of parameters on which it depends on time.


Basically, while the electric vehicle on a single charge ranges from 1 to 2.5 hours, depending on the incline of the road, the child's weight and evenness of the pavement. The modern market of children's electric cars is quite diverse. Every year there are new models little different from our usual adult cars. The most reliable are considered children's electric vehicles Peg-Perego, which are made in Italy. These electric vehicles manufacturer provides a 1 year warranty as opposed to the Chinese models.


On sale there are replicas of modern and retro car brands famous corporations, with leather interior, opening doors, trunk and hood, with the ignition keys and a set of tools for the repair of the road. Manufacturers offer a spare wheel, interior mats, batteries and more. Nobody will be surprised with additional music and sound effects, issued Children electric, glowing lights and rear-view mirrors. Therefore, if you plan to drive, along with his precious child, just choose an appropriate model, you will not regret!


Additionally, if you need to purchase some rc cars, you can search via Banggood website, which is one of the wholesale platform to provide affordable prices, such as remote control excavator, 2wd rc truck, etc.
