DO YOU ACTUALLY NEED DJI MAVIC PROPELLER GUARDS??

Recently, DJI released the new Mavic Propeller Guards. The guards cost a surprisingly steep $159 USD, and there has been a lot of skepticism about them online. A couple of days ago, DJI made a demo post of their new pricey accessory on the Chinese message app/social media platform WeChat, and they don’t look half bad:


Some may think the Mavic Propeller guards make the drone look like a futuristic spaceship, others may think they make it look more a toy. Regardless, they definitely make the drone bigger.



Of course the Mavic propeller guards make it impossible to fold the drone and reduce flight time, but some people always put safety first. Safety is exactly where the Propeller Guards shine.
Check out these GIFs:

As you can see from these GIFs, flying close to people or obstacles with the Propeller Guards attached shouldn’t be a safety issue.


Hitting the obstacles is also not a big deal anymore. This might become handy when flying indoors and in other places with no much space to fly like this forest:


Additionally, your Mavic Pro will not fall to the ground after hitting a ceiling, thanks to the new propeller guards.


Do you need the new DJI Mavic Propeller guards? 

  • If you are first time drone pilot – Yes
  • If you only fly in open areas with no obstacles around – No
  • If you want to fly indoors – Yes
  • If you want to fly in the forest – Yes
  • If you want to fly longer – No
  • If you want to hand-catch your Mavic – Yes
  • If you want to fly close to people – Yes
What do you guys think about paying $159 for an accessory to save $999? Let us know in the comments.

DJI INTRODUCES M200 SERIES DRONES !!

DJI, the world leader in unmanned aerial technology, Sunday unveiled the new Matrice 200 drone series (M200), which is purpose-built for professional users to perform aerial inspections and collect data – making drone technology an affordable and easy-to-use tool for enterprises that recognize how aerial imaging can transform their operations.



The M200 series’ folding body is easy to carry and easy to set up, with a weather- and water-resistant body, ideal for field operations. It offers DJI’s first upward-facing gimbal mount, opening up the undersides of bridges, towers and other structures to inspection. It is compatible with DJI’s powerful X4S and X5S cameras, as well as the high-powered Z30 zoom camera and the XT camera for thermal imaging. It has a forward-facing first-person view camera, allowing a pilot and a camera operator to monitor separate images on dual controllers. Its safety features include obstacle avoidance sensors facing forward, up and down, as well as an ADS-B receiver for advisory traffic information from nearby manned aircraft. With a dual battery set-up, the M200 platform can fly for up to 35 minutes with a mounted camera.



“Drones have quickly become a standard part of the enterprise toolkit and industrial users have come to rely on DJI technology to efficiently collect aerial data,” said Paul Guo, Director Enterprise Solutions at DJI. “With the M200 series, DJI introduces a holistic solution designed specifically for these users. We are revolutionizing professional workflows by making it possible to use advanced sensors in various combinations to make sophisticated tasks such as bridge inspections, land surveying and search-and-rescue missions, easier, safer and more reliable than ever before.”
The M200 series is designed for professionals using drones for more precise, efficient and safe aerial data collection. Examples of industry applications include:

  • Critical Infrastructure Inspections – work near power lines, telecommunications towers and bridges puts inspectors at risk of falls and electric shock. DJI’s M200 improves safety as work can be done from a distance. The M200 can identify millimeter-sized faults in buildings, roads and bridges in real time, making those operations more safe, efficient and effective.
  • Energy Facility Inspections – maintenance planning can be costly and time-consuming. With the stable and weather-resistant M200 platform, extensive power line networks can be visualized with unparalleled detail and vertical infrastructure, such as wind turbines and offshore oil rigs, can be inspected from all angles.
  • Construction Site Mapping – surveying and mapping often need to be conducted regardless of weather conditions and other external factors. The M200 is a rugged platform designed to handle tough conditions. The M200 gives construction site managers an efficient tool to review progress and workflow, ensuring more efficient use of resources.
  • Public Safety – when time is of essence and weather conditions turn foul, first responders require a versatile and reliable aerial platform. Carrying visual and/or thermal sensors, the M200 provides situational awareness of potentially dangerous situations such as fires, searches and natural disasters. Incident commanders can use data collected by the M200 to make smarter and better decisions, protecting life and property while minimizing the safety risk to rescue personnel.

Standard and Pro versions

The M200 series comes in three versions. The standard M200 is equipped with one downward-facing gimbal mount. The M210 opens up for multiple payload configurations – one single downward facing gimbal mount, two parallel downward-facing gimbal mounts or one upward-facing gimbal mount. The M210 features additional connectivity ports to support third party sensors and accessories. The M210 has the capability to support additional sensors in the future and additional payload can be mounted on top of the aircraft. TheM210 RTK is available with D-RTK modules for centimeter-precision navigation.

Unrivaled Safety and Reliability

With an IP43 classification, the M200 series is built to endure adverse environments. The aircraft is equipped with more than 20 internal sensors for maximum redundancy and reliability, including compass, GPS system, dual inertial measurement units (IMUs) and three barometers. Gimbal controllers have been integrated in the aircraft body for protection and to prevent drift. The aircraft features two stereo-vision systems below and in front of the aircraft and has an upward facing infrared sensor for obstacle avoidance. A redundant battery system improves safety and also allows the craft to stay powered while batteries are swapped in sequence.
The M200 series features DJI AirSense, a built-in ADS-B receiver, enhancing airspace safety by automatically providing the operator with real-time information about the position, altitude, and velocity of nearby manned aircraft equipped with ADS-B transmitters. AirSense enables safer and more efficient use of airspace, particularly in locations where other manned aircraft may be operating.
The M200 series is also equipped with an integrated flight controller, featuring two IMUs and a GNSS unit, with additional analytical redundancy systems. Working together with advanced diagnostic algorithms, it can seamlessly switch from one IMU to the other to maintain reliability and precision.    .
                    

DJI Flight Management

In addition to the DJI GO 4 app, the M200 series supports the brand new DJI Pilot app, which is specifically designed for enterprise users, optimizing user experience and flight performance. Users can also plan flights through DJI’s GS Pro app, which uses a clear and concise interface to establish complex flight missions with just a few taps.
The M200 series is compatible with DJI’s Mobile and Onboard Software Development Kit (SDK), enabling programmers to build customized solutions for flight planning, data collection and analysis.
The DJI Pilot app is compatible with DJI FlightHub™, a web-based software package allowing teams to share real-time data with offsite parties over the Internet. This includes remote emergency situation control rooms keeping track of first response teams or asset management centers inspecting global infrastructure networks. In an easy-to-use control center, DJI FlightHub lets users plan flights with multiple drones and keep track of each aircraft’s status. An offsite control room can simultaneously monitor live feeds and can remotely control gimbal and camera. The software enables managers to plan flights in advance using waypoints and dynamic geofencing.

Intelligent Flight Features

The M200 series’ computer vision enables intelligent flight modes to help with data collection. These features are available for multiple DJI sensors, enabling advanced shots such as zooming while tracking an object:
  • Spotlight – to lock the camera onto a subject during flight while the aircraft moves freely
  • Point of Interest – to circle around an object for a smooth orbit
  • Tripod – to fine-tune position and angle for position framing and safe navigation in narrow environments
  • ActiveTrack – to follow a person or object while keeping it in frame

Accessories

The M200 series pairs with DJI Goggles, displaying an 85-degree view from the drone in full 1080p for a bird’s-eye view of the world below.
The M200 series uses DJI’s powerful Lightbridge 2 system, supporting a range up to 4.3 miles (7 km) where, allowed by local laws and regulations, at live view resolutions up to 1080p. The master and slave controller range extends to 328 feet and users can switch between 2.4 GHz and 5.8 GHz frequencies to cut through any noise for greater signal stability.
The M200 series offers two battery versions – a standard 95 Wh version and a more powerful version of 174 Wh with flight time of up to 38 minutes.

M200 payloads

The M200 series enables three different payload configurations – one downward-facing camera (M200), two downward-facing cameras (M210) and / or one upward-facing cameras (M210).
DJI’s updated series of Zenmuse cameras is optimized for aerial imaging and communicates directly with the aircraft’s gimbal and flight controllers. For situations that require a balance between weight and image quality, the Zenmuse X4S has a 1-inch, 20-megapixel sensor with 11.6 stops of dynamic range and a 24 mm equivalent focal length. The Zenmuse X4S offers aperture control (f2.8-11) and a mechanical shutter capable of 1/2000 shutter speeds, eliminating rolling shutter distortion when taking images of fast-moving subjects or when flying at high speed. The Zenmuse X5S has a larger Micro Four Thirds sensor with 20.8 megapixels and 12.8 stops of dynamic range, and supports eight lenses from wide angles to zooms.
DJI’s Zenmuse XT, powered by FLIR, provides high-sensitivity thermal imaging ideal for analytics and telemetry. DJI’s Zenmuse Z30 is the first integrated aerial camera with an optical zoom up to 30x and digital up to 6x, making image data collection significantly faster while greatly reducing the risk of harm to both personnel and equipment.

Price and Availability

The M200, the M210 and the M210 RTK are available for pre-order from official DJI Enterprise dealers and will start shipping in Q2 2017. Pricing details and information on where to buy the M200 series will be announced in due course. For more information about the M200 series,

GOPRO KARMA DRONE SMASHES THROUGH OLD LADY’S WINDOW IN NEW YORK !!

A GoPro Karma drone smashed though the window of a 66-year-old lady living on the 27th floor of 20 Waterside Plaza in Manhattan, New York. The woman was working on a computer when the drone smashed right though her window and fell within 4 feet of her. Currently, the Police and Federal Aviation Administration are investigating the accident. They are planning to use the drone’s serial number to locate the drone owner in the FAA’s database.

It could have been any other drone, but it was the GoPro Karma

Yes, it could have been any other drone. But let’s take a look at this issue from the technical point of view.
First of all, we know that GoPro Karma proved itself to be an unreliable drone when it started falling from the sky for no good reason in November 2016.
Second, GoPro Karma has no obstacle avoidance. Other drones like the Phantom and Mavic have obstacle avoidance. They can’t recognize transparent glass, but at at least those drones could recognize the window frame and stop automatically.
Lastly, the pilot probably didn’t fly into the poor lady’s window intentionally. We know that flying drones close to buildings can cause some magnetic interference that will influence the drone’s compass. Sometimes this leads the drones to get out of control and fly erratically. Most drones, such as the Mavic and Phantom, have 2 compasses and IMUs for better redundancy. Unfortunately, the Karma only has 1 compass, like the drones from 2-3 years ago, so that might have caused the incident.

We don’t have all the details yet, but we do know the specs and reliability record of GoPro’s Karma. From that, we can assume that the Karma is more likely to wind up in a situation like this.
But of course, the most important factor here is the irresponsible pilot. Please don’t be like that guy! Fly responsibly, and you’ll be less likely to end up in the news.

A MAVIC PRO KNOCKOFF – THE ZEROTECH HUNTER EXUDES UNORIGINALITY !

The Zerotech Hunter bears a strikingly strong resemblance to the well-known DJI Mavic Pro. Apparently, Zerotech’s design team was so “creative” they thought, “Why bother making something original when we can just copy the Mavic?” This is actually the second case of a competitor copying the DJI Mavic Pro. Walkera, well known for “borrowing” DJI’s designs, released the Vitus at CES 2017. That drone was some kind of Inspire 2 and Mavic Pro offspring.

Zerotech Hunter Hunts the Mavic?

Before we elaborate, check out this side-by-side comparison of the Hunter and the Mavic:



Not much else to say here. Zerotech might want to start preparing for a patent infringement lawsuit, like the one DJI filed against Yuneec.
According to SB-DJI, a Chinese drone blog, the Zerotech Hunter will have a fight time of about 15 minutes and flight range of 1.5km (4500ft). Unfortunately, we don’t yet know what this drone’s remote controller is going to look like or whether or not it will come with a gimbal camera. Obviously, if the Hunter relies on digital image stabilization and has no gimbal, this drone will be classified as an expensive toy. But if Zerotech adds a tiny 3-axis gimbal to it, it might become the first real Mavic competitor on the market.
What are your thoughts about the Hunter?

PHANTOM 4 PRO VS PHANTOM 4 – SHOULD I UPGRADE??

Time to compare the Phantom 4 Pro vs Phantom 4. It has been only 8 month since DJI announced their bestseller Phantom 4 and already we see the release of the Phantom 4 Pro. A lot of folks expected it to be Phantom 5 next March but DJI released the update on the middle of November which begs to ask, is it possible to make any reasonable upgrade in such a short time? Well, in DJI’s case, the answer is a resounding yes!
When there are a new generation of products coming out there is always that nagging question, “Should I upgrade?”  Here at We Talk UAV we like to clarify such questions by giving you a better idea of what are you getting from this upgrade. 
Now take a look at our colleague Alex explaining and showing all the differences between those 2 drones!

Phantom 4 Pro vs Phantom 4 Specs


That’s a major upgrade and really gives professional drone pilots something to think on. The upgrade to 20 MP camera and 360° Obstacle Avoidance are certainly a game changer.

Here are some things you need to know before you buy Phantom 4 Pro:

  • The batteries for Phantom 4 Pro are 5870 Mah, however for Phantom 4 it’s different: 5350 Mah which explains why the flight time of P4P is longer. However, what is surprising is that both kinds of batteries can be used on both drones.
  • You can buy Phantom 4 Pro without built in super bright 5.5 inch Full HD display for $1799 or get a version with standard RC and save $300.
  • Another bonus with this release is you don’t really need ND Filters for Phantom 4 Pro camera because you simply can change an aperture.
  • Some intelligent flight modes like Profile Active Track, Draw Mode and Gesture mode probably will be coming to Phantom 4 with firmware upgrades in upcoming 3-4 months.
  • Yes, Phantom 4 Pro will be cheaper one day in the same way that a release of a Phantom 5 or another drone will have more advanced technology by that time.
  • There is no other drone on a market that is more advanced that Phantom 4 Pro in this price range.
Case in point: if the iPhone 6s to iPhone 7 wasn’t a big step up, or Canon 70D to 80D did not really surprised you, the release of the Phantom 4 Pro may surprise you in terms of both hardware and software.
The Phantom 4 Pro vs Phantom 4… Should you upgrade? If you can afford it you definitely have to go for Phantom 4 Pro. You won’t be disappointed. Or you can wait and watch our review of Phantom 4 Pro that is coming soon and make a decision after that.

DJI INTRODUCES NEW SHAPES OF NO FLY ZONES FOR CHINESE AIRPORTS ,


DJI recently released new polygonal No Fly Zones in Mainland China that are not only safer, but also more logical. The newly-shaped No Fly Zones (NFZs) have only been implemented around airports. Other No Fly Zones, such as those around stadiums and government buildings, remain unchanged.

Here is what a new airport No Fly Zones looks like:

No Fly Zone (R1): The center consists of 2 circular NFZs combined into an oval. The circles are centered on each of the runway, and both have a radius of 4.5km.
Limited Altitude Zone (R2):  The trapezoidal zones (a) extends 15 km from each end of the runway. In “a” zones, flights are limited to 60 meters. All flights within R2 are limited to 30m.
120m Limited Altitude Zone (R3): This circular NFZ is centered on the middle of the runway and has a radius of 10km. Flights in this zone are limited to 120m.
You also can check out the video that explains how the new NFZ works in Chinese here.

Other No Fly Zones:

  • To guarantee public safety DJI has prohibited flights within 100 meters of government buildings, prisons, military bases, and other sensitive areas.
  • Temporary NFZs for the big events at stadiums and and public squares will continue to be used as well.

If these new NFZs work well in China, DJI may implement them all over the world.

PHANTOM 3 SE – DJI’S NEW OLD DRONE OFFERS POWER FOR A LOW PRICE 2017


DJI has released a somewhat brand new drone called the Phantom 3 SE, and it will cost only 2999 Chinese RMB (about 430 USD). You may be asking yourself, “Didn’t they stop the production of all Phantom 3s except Phantom 3 Standard?” That is right. The reason for this was the fact that DJI had too many Mavic orders, and they had a hard time satisfying demand.
Looking at DJI’s current pricing strategy, one can see that they have a lot of drones between $700-2000 USD, and there is only one entry-level drone: Phantom 3 Standard, that costs $399.

What is the Phantom 3 SE all about?

Unlike the regular P3S, the Phantom 3 SE has a 4K camera and 720P live view with a maximum RC range of 4000m (12000ft).  Think of it as an improved version of the short-lived Phantom 3 4K.
The main differences:
  • 4K Camera
  • Improved 720p, 30 fps Wi-Fi live view
  • 4000m (12000 ft) RC Range
  • Vision Positioning System
  • New name
According to an unofficial source, this product will only be sold in the Chinese market, at least for now. Maybe they want to see if people are actually going to buy it, and if it works, before they sell it in Western market as well.
Innovation? – Not at all! But for about $430 bucks this is arguably the best drone in this price range on the market right now.
