Exclusive! DJI will release faster and lighter new Mavic Air?

At the worldwide concerned CES, DJI released only two new hand-held PTZs, Osmo Mobile 2 and Ronin-S. Recently, the internet was reported that DJI will hold a news conference in New York this month (January 2018) on the 23rd. DJI will be launching the Mavic Air which is even faster and lighter than the star product Mavic Pro. DJI confirmed the conference news on the 16th but did not reveal the details. We also initially received DJI's invitation for a conference in Hong Kong on the 25th. Without any detailed information, we can say that the confidential work is done very well. This mysterious feeling makes it even more anticipated.

DroneDJ.com published an article on last Friday (12th), referring to the invitation by DJI to participate the activities this month, 23rd, in New York. In addition to the time and place of the invitation, the invitation was merely printed with the slogan "Adventure Unfolds," as well as the silhouette of a streamlined body, without revealing any other details. On the night of the 16th, DJI confirmed on its official website and Facebook page about a press conference in New York on the 23rd, stating that "a big surprise prepared by DJI will debut on January 23, so stay tuned" and attach a trailer.

Also, DJI will hold a conference in the Hong Kong flagship store on the 25th, which will also be one of the most important conferences of the year, but the details of the event is not clear either.

DJI Mavic Pro Platinum

DJI released an upgraded version of Mavic Pro in 2017, called Platinum. We estimate that DJI will release a smaller, lighter and faster new machine than the Mavic Pro, which we believe to be called "Mavic Air". Since DJI's Mavic Pro RC Drones still have some price gaps with Spark, Mavic Air might appear at an intermediate price between $600 and $900. However, there are netizens who estimate that it will be the Phantom 5 or a new, collapsible Spark to be released that day. We’ll see. 

Drone can save lives now

Australia time 10 a.m. on January 18, 16-year-old Monty Greenslade and 17-year-old Gabe Vidlerwere swimming by the coast of Lennox Head, New South Wales (NSW), and unfortunately washed away by the waves. Fortunately, two teenage girls found them struggling in the sea. The two boys were trapped by a 10-foot-high ocean wave, and the boats were unable to get near them, but eventually, a drone took off and sent them an inflatable life-saving device to save them.

FPV Quadcopter has recorded this whole scene - the remote drone flew to the top of two boys and dropped an inflatable life-saving device, and landed the inflatable rescue pod within their reach. The drone took the life-saving device to them in less than 35 seconds. They clutched the life-saving device and were washed back to the shore by the waves, and finally, the lifeguard saved them.

The two boys were completely safe now except for fatigue. Ben Trollope, chief search and rescue drone operating officer of Westpac Little Ripper, claimed: "Two teenage girls called the Coast Command and we sent a rescue squad. The device was inflated in seconds. "

Team CEO Eddie Bennet said: "UAS technology has been developed for three years to ensure the world's first rescue mission is completed and the rescue of two boys trapped in a 3-meter-high ocean wave clearly demonstrates the benefits of this cutting-edge technology in such a time-critical emergency, which can be said as a huge success of drone rescue and Australia is ahead of the world in this technology. "

In December 2017, the state government bought more than $ 430,000 to buy several drones. In addition to life-saving RC Quadcopter equipped with life-saving float, alarm system and loudspeaker, a part of the drones are specially designed to detect offshore sharks to ensure the safety of surfing people.

Ten ways to extend the UAV flight time - part 1

Like many tech geeks and drone lovers, you may also be disappointed with the drones' short flight times. The average flight time for an entry-level quadcopter is only seven minutes. Even the most expensive drone, the longest flight time does not exceed 30 minutes. Even so, you can still do something to extend the flight time of your quadcopter. Next, this article will share 10 ways to help you extend your drone's lifetime.

What are the factors that affect the UAV lifetime?

Today's entry-level quadcopter RC Drones will last for approximately 7 minutes for a flight, such as the Syma X5C and the UDI U818A. Obviously, there are many factors that can reduce the life of your UAV, including wind, weight, flight style, and video. For example, UAV life in windy weather will be shorter than usual. Flying UAVs with heavy payloads, such as a camera or paddle cover, or fierce flights can result in significantly reduced battery life.

Method 10: Use a larger battery

Today almost all UAVs use lithium-polymer batteries. Lithium-polymer batteries are light in weight and discharge at higher rates (more energy can be stored/released) than conventional batteries. As you might expect, lithium-polymer batteries come in many sizes: the Cheerson CX-10, the smallest quadrocopter in the world, uses a relatively small 100mAh battery, while the larger Syma X8C rc fpv uses a 2000mAh battery. In general, a larger battery can support longer battery life. Note: Sometimes, the battery's large capacity is not necessarily a good thing because larger batteries usually mean more weight. If the battery is too heavy, it may shorten the lifetime of the drone.

Method 9: Remove the camera (if detachable)

It is worth noting that camera and UAV lifetime are closely related. So when you record a video, you will need more battery power than usual (not available on the Hubsan X4 H107C since the camera is not detachable). This method can be only applied to the rc camera drone.

Method 8: Grasp the charging opportunity

The correct charging time can extend battery life. In order to ensure the best lifetime, before each use, you should be the right charge. If you do not intend to fly a drone in the near future, no need to charge. Just fully charge the battery before you decide to use it.

Method 7: Avoid flying in inclement weather

Flying drones under the strong wind weather is dangerous and can cause the drone to fall or even injure innocent people. When you fly a drone in strong winds, it is equivalent to forcing the motor to generate more momentum to keep hovering. This will result in more battery power consuming, and if you can, choose to fly indoors in windy weather.

Method 6: Choose a conservative flight mode

Almost all UAVs have multiple flight modes for you to choose. If you want to choose more intense flight mode, only need to increase the sensitivity of the remote control; otherwise, reduce the sensitivity of the remote control. Obviously more intense flight mode needs to consume more battery energy. You can purchase some high-quality rc model tools online.

Method 5: Avoid overcharging

Lithium polymer batteries are highly volatile. If the charging time is too long, it may cause an explosion or even cause a fire. Overcharging is not only dangerous but also shortens battery life.

Method 4: DIY yourself

Why not try DIY? With your own DIY quadcopter, you have better control over your battery life. Do not worry - it's not as difficult as you think. There are many online resources to teach you DIY step by step. if you plan to DIY, I suggest you read this article:

http://beginnerflyer.com/build-a-drone/. This article will at least teach you some quadcopter drone DIY foundation knowledge. You can also refer to these websites below:

RCGroups.com: RC Groups was founded in 1995 to help you meet like-minded four-rotor UAV enthusiasts. Here you can not only learn the knowledge of drones and how it works but also experienced flyers for you to answer questions.

DIYDrones.com: This online community is devoted to helping UAV novices learn how to DIY a Quadrotor UAV. As far as I know, the users on this site are friendly, open and helpful.

MultiRotorForums.com: This site is also a great resource for learning how to DIY a drone. Thousands of users are sharing their ideas and suggestions here every day, freely offering solutions. The site also has an "Activities" section where you can get the latest local drone information.

Method 3: Backup Battery

To date, one of the most common solutions to the problem of limited battery life for drone spaceflight is to purchase a backup battery. This method is suitable for UAVs that are easily replaced by batteries (such as X8C and X5SW) but not for UDI U839. In general, spare batteries are cheaper (about $ 5). You can buy at:

Amazon.com

Banggood.com (all kinds of rc drone parts at an affordable price)

Method 2: Remove the blade guard

Paddle guard is mainly used to protect the UAV propellers, but also has its drawbacks, they provide protection while increasing the weight of the UAV leading to shorter life. However, if you are not familiar with the UAV control method, I recommend not to remove the blade guard in a hurry. Because it is more important to protect the propeller than to fly for a few more minutes. We will recommend the Carbon Fiber Tube as it is super lightweight.

Method 1: Do not run out of battery

Our last advice is: Never run out of battery power during the flight as this will gradually shorten the battery life. We recommend flying with a battery charge greater than 20%. When the battery level drops below 20%, allow the battery to cool for a few minutes and then fully charge it. Such regular maintenance can help you extend battery life.

Key point

Keep in mind that these methods of extending the life of the drone have a limited effect and can not make your drone's duration soar from seven minutes to 14 minutes. Based on this premise, these methods are really useful and can help you get longer battery life. If you have other good ways or tips to prolong your drone's life, please feel free to share it in the comments section below.
