Commercial Delivery Drones Use

Architecture and construction

Architectural firms and construction contractors are also benefitting from the use of best drone for 4k video. Much like professionals in real estate, architects can use images and footage of a property to create 3D renderings of the structures they aim to build.

By cheaply and quickly creating aerial shots on which to place an architectural rendering, architects can create real-world concepts of their projects. This ability is indispensable to creating accurate designs and understanding how they fit within properties.

Access to these plans during the construction project is also useful to the people actually bringing the design to life.

Delivery--Commercial uavs Drones
Drone-based delivery services probably constitute one of the most obvious applications.

But the promise of goods delivered direct to your door by drone will only become more real as the technology continues to evolve and its capabilities expand.

This is especially true for areas where traveling by road is difficult or treacherous.

Emergency Services
Using professional 4k drone for emergency response services, particularly when it comes to medical needs, presents new opportunities for life-saving measures. Using drones to get eyes on a difficult situation, or to deliver medical supplies to stranded victims, could enhance the ability of emergency response physicians to offer care in difficult situations.

Engineering
Engineering firms are also utilizing drones on in-depth projects like oil pipelines, transmission cables and maintenance inspections.

Environmental monitoring and conservation
Much like how farmers use commercial grade drones to monitor crops and animals, the technology can be utilized to keep tabs on ecological environments. UAVs are discrete and can monitor animal populations without disturbing them. This type of monitoring offers important insights into conservation efforts, migration tracking, habitat management and flood assessment, which is particularly useful on the coasts.

Drones also provide data on the health of vegetative and animal populations, and the technology offers a unique ability to identify species in hard to reach places.

Media
Another obvious use for drones is in media coverage. Previously, aerial shots were available only to large news corporations that could afford a news helicopter. Now, local journalists and small-scale media outlets can easily capture aerial footage for news coverage.

In addition, drones can get into tighter areas, lower to the ground than a news helicopter could ever hope to travel. Even simple tasks, like recording a face-to-face interview, can easily be made more dynamic and engaging with a camera-equipped drone hovering nearby.

FPV 4s Drone Battery

For most drone newbies, racing drone battery is very important to know how to choose a best 4s lipo battery for your drone, multi-rotors are fueled by LiPo battery, they are able to store and deliver large amount of power.

Since they're made of individual cells, the battery you buy ends up having the voltage of all the cells combined. So, if you get 3S batteries, they will be 12.6v charged, and 11.1v discharged. 4S will be 16.8v charged and 14.8v discharged. If it's not clearly labelled, you will be looking for the label "11.1v" or "14.8v" on a battery to determine if it's a 3S or 4S. You never ever never want to fly a battery down to 0v. This is why you use certain gear to monitor battery voltage while flying.

Commonly for 5-inch mini-quads, 1300mAh to 1800mAh are the most popular batteries, although the sweet spot is usually 1300mAh or 1500mAh. Smaller capacity batteries work fairly well for lightweight builds because they weigh less, so the drone needs less power when flying, but they do reduce flight time. Higher capacity batteries increase flight time, but make the quad heavier, meaning it needs more juice to stay in the air anyway. This is why 1300 or 1500 mAh is the sweet spot. They have enough capacity to have good flight times and are also light enough to not put the capacity to waste on heavy lifting.

We always be strict of product quality, all of the rc drone battery complies with RoHS and CE quality testing standards, worry-free of safety. And we are devoted to provide the best racing drone battery and the best fpv battery all the time.

Please Attention:

► For the RC UAV battery, only if the voltage and the plug match, then it will fit.

► Please stop charging immediately when the cell voltage been charged to 4.2v (Normal cell voltage is between 3.7v~4.2v).

► To double make sure safety, please have a check first whether the battery surface is alright when you get it and whether the voltage is normal before using.

► If the new fpv drone battery won’t hold a full charge or loss the charge very quickly in short time, please use Balance Charger to charge and recycle several times first.

Now that you have chosen or designed a UAV frame, chosen the appropriate motors, propellers, ESCs and battery, you can start looking into choosing a flight controllers. A rc flight controller for a multi-rotor UAV is an integrated circuit normally made up of a microprocessor, sensors and input/output pins. Out of the box, a quadcopter controller does not magically know your specific UAV type or configuration, so you need to set certain parameters in a software program, and once complete, that configuration is then uploaded to board. 

What is a Quad Flight Controller ?
A flight controller (a.k.a FC) is the brain of the aircraft, which is basically a circuit board that has built-in sensors that detect orientation changes. It also receives user commands and controls the motors in order to keep the quadcopter in the air.

Nearly all diy drone flight controller has basic sensors such as Gyro (Gyroscopes) and Acc (Accelerometer). Some FC might include more advanced sensors such as Barometer (barometric pressure sensors) and magnetometer (compass).

Mini f3 flight controller is also a hub for many other peripherals, such as GPS, LED, Sonar sensor etc.

Brushless DC electric motor (BLDC motors, BL motors) also known as electronically commutated motors (ECMs, EC motors), or synchronous DC motors, are sensored brushless motor powered by DC electricity via an inverter or switching power supply which produces an AC electric current to drive each phase of the motor via a closed loop controller. The controller provides pulses of current to the motor windings that control the speed and torque of the motor.

Powerful brushless motor exhibit reduced energy use, long life, low noise, compact size and light weight characteristics.

Choosing a good high power brushless motor can be easy and difficult at the same time. There's a few things to take in consideration when choosing one high speed brushless motor for your plane:

1- Prop size; Do you want the plane to be fast or slow? How much clearance do you have?
2- Amps; How many amps does the motor pull? More means more power
3- Voltage; 2s or 3s lipo? 2s would be better for smaller, lightweight planes.
4- kv; kv determines how fast the motor spins. Generally the higher the kv, the smaller the prop
Keep all of those in mind and you will be able to find the PERFECT motor for your plane.
5- Thrust; How heavy will the plane be? Heavier = need for more thrust to stay airborne

Your entire plane is built around your powerful rc motor and this is what you must choose first. When considering RC brushless motors there are several pieces of information you must take into account. The first is your drone parts motor KV. The KV of your motor is the number of revolutions per minute it will spin per volt. The lower the KV, the stronger the motor and as a result, you will want a larger propeller for maximum thrust. Often slower motors will also result in slower flying planes, a big plus for your first hobby grade RC drone. If you select a rc drone motor with a higher KV and a smaller propeller the speed of the thrust will be higher, and as a result your drone will fly faster.

Having a good quadcopter frame is just as important as having good electronics, as drone depend on lightweight, sturdy hulls for mounting components. There are limitless frame designs that vary in shapes, materials and dimensions. Stiffer frames result in better flight characteristics since less bending and warping can occur, meaning your quadcopter will be able to have a smooth and stable flight.

One of the materials of mini quad frame that is most common for custom drone frame is carbon fiber.

These frames of fpv kit drone are great for drones because of their physical properties which makes them perfectly suited for the hobby. 

The most common drone categories are aerial cinematography, sport, sport FPV, mini, and diy drone frame FPV. All of them will need a different frame, from aerial cinematography quadcopters that will need tall landing gear and be large enough to lift a high quality camera, to sport quadcopters that are very light weight, fast, and have extremely responsive control.

When you have finally picked the right mini quadcopter frame, it’s always a good idea to ensure that you know how you are going to mount the flight controller. This is because certain flight controller boards come with cases that allow you to use double sided sticky tape so you can mount it to any frame, because, most boards only have mounting holes.

Choosing a motor/battery/ fpv drone ESC combo is a combination of science, guess-work, and magic! Here is a process to select the "right" motor, ESC and battery. 

(1) Estimate the AUW ("All-Up-Weight") of the plane;
(2) Select a motor and propeller with (a) the proper thrust, and/or (b) the proper power, given the estimated AUW;
(3) Determine the battery voltage compatible with the motor;
(4) Determine what flight times you want;
(5) Select a battery with the desired voltage and capacity;
(7) Determine the resulting current flow in Amps; and
(6) Select an ESC compatible with motor type (brush or brushless motor), and battery type (NiCD, NiMH and/or Li-poly) that can handle the maximum current your motor and prop will draw.

After selecting a motor, the next logical step is to select a brushless electronic speed controller (ESC) that matches your motor. The motor will have an Amp (A) rating, quadcopter esc is good general practice to select an ESC rated for 30 percent or 10A more than the max current draw of your motor. Say I have a motor that pulls 10 amps. I do not want to buy an ESC that is rated for 10 amps. I would want to get an ESC that is rated for 15 or 18 amps. It is always good to go higher. The higher amp-rated ESC you get the less heat will be radiated.
Speaking of heat, this ESC can get very warm at times! That's why it is important to get a ESC with an amperage rating higher than your motor or your motor will pull too many amps through the ESC and cause the ESC to overheat and possible catch fire.

Brushless Speed Controller ESC Types
For base on motor, ESC can be divided into brushed and brushless. It according to the control signal to adjust the speed of the motor.
#1 Brushed and brushless

For their connection, control esc usually goes like this:

The ESC input line connected to the battery;
The output of the ESC line (brushed have two lines, brushless have three lines) connected to the motor;
ESC signal lines connected to the receiver.
