When Should You Replace / Upgrade Your Drone Propellers?

By the end of 2018, it is expected that the consumer drone market will grow to over $1 billion in sales. That number is not really a surprise since from farming to photography, the use of drones permeates a massive variety of industries. Not to mention, they are a great time to fly.

Whether you need to replace your propellers because they are damaged, or you’re just ready for an upgrade, the right propellers can enhance your drone game. From propellers to drone motor Xoar has the innovation to take your drone higher. You should replace your propellers with new (more enhanced) props if:

They’re damaged

Not only can having damaged props make flying noisier, but it can also increase the vibrations, which in turn can shorten the life of motor bearings due to a lack of balance. So, if you see any cracks, nicks, or deformations, it is time to replace your propellers. Never fly your drone if there are chunks or tips missing from your props.

You want it quieter

This can be particularly important if you fly in largely populated areas, as you’ll annoy fewer people with a quieter drone. The talented fellas over at Drone Gear reviewed Xoar’s beechwood drone propellers and found them to be almost 10 decibels quieter than their counterparts.

You need more agility

Updating your propellers can provide you with increased agility, if you upgrade to a stiffer material, your drone will be more responsive without added drift.

You fly in high altitude

If you want to take your drone to new heights, you should invest in stiffer propellers. The higher the altitude, the thinner the air, which means that to perform at the same ability as sea level, the thrust from the props must increase while in higher elevation. As such, performance degrades at approximately 3% per 1000 feet as you climb in altitude. Your drone has to work harder the higher it flies.

You want that new drone feeling again

Replacing your propellers can make it fly like it’s new again. If you’re upgrading from standard props to a more agile performance-based prop, you’ll see a drastic difference in performance.

The Many Ways Drones Are Becoming Invaluable for Scientific Research

05JanMarch 5, 2019 By Xoar Propeller

Anyone familiar with drones is no doubt aware of their military use and their burgeoning popularity among hobbyist unmanned aerial vehicle (UAV) pilots. While most are likely aware that they’re increasingly employed for commercial applications as well (cinematography, delivery, agriculture, etc.). However, less well-known is that drones are becoming an increasingly invaluable asset to scientific research. That value is proving to be an impressively prolific one, too.

In fact, drones are being taken advantage of by biologists (micro, marine, terrestrial, etc.), climatologists, geologists, ecologists, volcanologists, and meteorologists—so scientists in pretty much every branch of natural and life science are benefitting from the use of UAVs. Drones are demonstrating an ability to reach places with more agility, easier access, and (extremely important for virtually all scientific studies), far lower cost than other research media are capable. The following is a record of just a few of ways in which drones are emerging as a precious scientific aid, both above water and land.

Above Water

Drone technology is being deployed over bodies of water for a variety of reasons. Thermal imagery from above is revealing fascinating, and often daunting, data regarding the effect of climate change on coastal regions. It’s proven particularly beneficial in arctic and Antarctic ecosystems. Drone propellers, being safer to engage right over the surface of oceans, rivers, ponds, and lakes, allow UAVs to perform a more active role.

In a series of studies undertaken in the Arctic and tropical waters, drones have dropped pods the size of a soda can called “micro-drifters” that collect and analyze the atmosphere for temperature, pressure, and water vapor levels. Once in the water, a micro-drifter functions as a sort of micro-buoy capable of recording and transmitting data about salinity and temperature measurements at different depths back to the drone.

Biologists have also been using drones to collect a wealth of health and other biological information from the blowhole exhalations of whales. In fact, an analysis of just 19 whale blow samples revealed six new species of virus from five different families.

Above Land

It’s known that animal research is often influenced by the fact that observing the subjects can influence their behavior. Drones have been found to at least mitigate this. Scientists and citizen scientists alike have been able to observe populations of bears, flamingos, sea turtles, leopard seals, the earlier-mentioned whales, migratory seabirds, and many, many more, with drones. And apparently, they do so with significantly greater accuracy than more traditional means. This, along with the emergence of less intrusive drones, such as ones made to resemble small creatures like hummingbirds, means the observing can be done with even less stress to the studied populations.

In a practical application that could save farmers a good amount of money, drones have recently been used to identify diseased olive trees by temperature differentials, which allows the scientists to cull them before they show symptoms (which is long after they are contagious).

Additionally, a team in Costa Rica took advantage of the fact that a drone motor isn’t as at risk of having its engine clogged with ash to study the noxious, poisonous gasses being vented by volcanoes. On top of these examples, there are dozens of additional experiments being undertaken with drones, and seemingly, only more to come.

The United States Federal Regulations Surrounding Drone Ownership

05AugMarch 5, 2019 By Xoar Propeller

Gone are the days of free, unrestricted drone flying in the U.S. Since 2016, the Federal Aviation Administration (FAA) has been rolling out regulations and restrictions that maintain safety in the airspace above us. You must adhere to these restrictions whether you fly for fun or for your livelihood.

In addition to these restrictions, you should also respect your fellow flight enthusiasts and those around you. One way to do this is to spring for a quieter drone motor. It’s also a good practice to check the skies before you fly so you’re aware of any other drones already in the airspace.

If you fly for fun

Flying for recreation has a different set of guidelines than commercial drone flying. You will need to register your drone aircraft with the FAA. Registration costs $5 and is valid for a period of three years.

In addition to registering your drone, as a hobby flyer, you’ll have to keep your drone at or below 400 feet and in your line of sight. Your drone must weigh under 55 pounds unless certified by a community-based organization.

You will also have to adhere to temporary flight restrictions that occur during hazardous conditions such as a wildfire or chemical spill.

If you fly for work

Under the FAA’s Small Unmanned Aircraft System (UAS) rule, you can register your drone for commercial and recreational use. If you use your drone for any commercial operations, you’ll want to choose this option. You will still have to register your drone with the FAA, and the cost to do that is still $5 per aircraft, which is valid for three years. However, unlike a hobbyist, you’ll need to label your unmanned aircraft with your registration number.

You’ll also need to acquire a remote pilot certification from the FAA, fly a drone under 55 pounds, and maintain a visual line-of-sight while flying. You also can’t fly in controlled airspace or near other aircraft or over people. Fly only during daylight at or below 400 feet.

Some of these rules, like visual line-of-sight and flying over people, can be waived by completing a special request with the FAA.

Registering your drone

In order to register, you’ll need to visit faadronezone.faa.gov, meet the following criteria, and have these materials:

Be at least 13 years of age (if the owner is younger have an adult register)
Be a U.S. citizen or legal permanent resident
Email address
Credit or debit card
Physical address and mailing address (if different from physical address)
Make and model of your unmanned aircraft

Where you can’t fly

In addition to temporary flight restrictions, there are also restrictions that limit any flying of drones in a no drone zone, and you must never fly near any emergency response efforts. Also never fly near other aircraft. If you’re flying within 5 miles of an airport, you must notify air traffic control.

Where you shouldn’t fly

Maintain a respect for others when you fly. Don’t be a nuisance who disrupts others. Follow the FAA guidelines, and you’ll be having fun with your drone for years to come.

XOAR congratulates the VAMUdeS team once again for an amazing performance and crowning champion of of the international competition AUVSI SUAS 2018.

Check out the VAMUdeS team on facebook.

About the Competition
The AUVSI SUAS Competition is designed to foster interest in Unmanned Aerial Systems (UAS), stimulate interest in UAS technologies and careers, and to engage students in a challenging UAS mission. The competition requires students to design, integrate, report on, and demonstrate a UAS capable of autonomous flight and navigation, remote sensing via onboard payload sensors, and execution of a specific set of tasks. The competition has been held annually since 2002.

The competition is held at the Patuxent River Naval Air Station (NAS) Webster Field in St. Mary’s County, Maryland. This is the site of the UAS Test & Evaluation Directorate.

Autonomous Aerial Missions.
The competition focuses on Unmanned Aerial Systems (UAS) performing autonomous missions. Many of the tasks require autonomy to be eligible, and others receive more points for autonomy.

Competition Components.
The competition has 3 major graded components: a Technical Journal Paper which describes the systems engineering approach and the UAS design, a Flight Readiness Review (FRR) where teams describe their mission readiness and what testing gives them confidence, and a Mission Demonstration where the team is evaluated on performance.

Mission Tasks. The competition has a series of tasks that should be completed by the UAS system built. The competition changes these tasks year-to-year to reflect the forefront of the UAS industry. The tasks are joined to form a simulated real-world mission. The 2017 competition mission is search-and-rescue of a lost hiker. Example tasks:

Interoperability. The UAS downloads mission details, uploads aircraft telemetry in real time, and uploads mission deliverables to an external judge-provided system.
Autonomous Flight. The UAS autonomously takes off, flies within boundaries, navigates a series of waypoints, and lands.

Obstacle Avoidance. The UAS autonomously avoids obstacles, which can be stationary or moving.
Object Detection, Classification, Localization. The UAS takes pictures of a search area, detect objects of interest, classifies its characteristics, and provides a GPS position.

Air Delivery. The UAS autonomously drops a payload object so that it lands undamaged at a provided GPS position.

EHang184 – World’s First Human-size Autonomous Aerial Vehicle

08JanJanuary 18, 2016 By Xoar Propeller

World’s first electric human-size autonomous aerial vehicle (AAV), EHang184, was unveiled at CES 2016 at Las Vegas.

EHang184 is capable of carrying one passenger up to 220 pounds for up to 23 minutes at sea level with its 14.4-kWh battery pack, which takes four hours in triple mode or two hours in fast charge to a full charge. The whole vehicle weights 440 lb (200 kg), can carry up to 264 lb (120 kg), has a maximum speed of 62 mph (100 km/h) and can reach a maximum altitude of 11,480 ft (3,499 m).

It features a carbon fiber/epoxy composite body and an aerial aluminum alloy frame. Eight motors with eight carbon fiber propellers divided in four group of two, each pair mounted on the top and bottom of one of four foldable arms.

A 12-inch touchscreen tablet display is the main instrument in the cockpit which allows the passenger to select the flight destination. The drone has gull-wing doors and a trunk for small luggage.

Safety is key on EHang184 with its fail-safe system. Even with one propeller malfunctions, it can still land in the nearest possible area safely. EHang also claims a 24-7 flight control center monitors each flight and can intervene in emergency situations.

EHang184 is a great start to the future of autonomous aviation, but it will require the Government, FAA and the commercial manufacturers working together to set the future in the right direction.

Malloy Aeronautics Hoverbike

23JunFebruary 1, 2018 By Xoar Propeller

Latest news on Malloy Aeronautics’s Hoverbike at Paris Air Show 2015, it is partnering with a Maryland-based defense company to develop a hoverbike for the US military. Working with Survice Engineering Co., the UK aeronautics company will set up shop in Maryland as part of “an ongoing research and development contract.” The duo will also work with the US Army Research Laboratory on the project that aims to create “a new class of Tactical Reconnaissance Vehicle (TRV).”

While developing for the military will play a big role in the future of the technology, Malloy was keen to emphasize that there’s still a lot of potential for the use of the tech in humanitarian applications. For example, multiple Hoverbikes could be loaded into troop carrier aircraft (the vehicle is designed to fold up for easier transport), dispatched to disaster zones and tasked with delivering vital supplies, or even autonomously removing people from danger.

Mooney – An Aviation Legend Is Back

10MayFebruary 1, 2018 By Xoar Propeller

Mooney Aviation Company, Inc (formerly the Mooney Aircraft Company), founded by Albert Mooney and his brother Arthur in 1929, has gone through a very rich history. After going through many years of ups and downs, Mooney Aviation got acquired by Soaring America Corporation in 2013 headed by President Jerry Chen who is looking to lead the aviation industry for the legendary brand.

Mooney’s history of innovation includes designed and produced the first pressurized single-engine, piston-powered aircraft (M22 Mustang), first production aircraft M20J 201 to achieve 200 mph on 200 hp, first single-engine power-control certified (FADEC) aircraft M20L Porsche in the United States and much more.

Mooney also has great achievements in the aviation history by setting 132 world speed records, designed and produced the fastest transcontinental flight in a single-engine, piston-powered production aircraft, and routinely cruising at altitudes and speeds similar to a twin-engine turboprop.

Mooney now has a manufacturing facility in Kerrville, Texas, which occupies 270,000 square miles with a base of more than 100 employees. They also have a research and development facility in Chino, California is leading the development of the all-new Mooney M10 series aircraft. There are currently more than 70 employees which more than 50 of them are engineers. And a sales and marketing office based in Beijing China to coordinate overseas events.
