The History Of Quadcopters

Untitled design (1)

The term ‘quadcopter’ refers to an aircraft with four rotors that are powered by either internal combustion or electric motors. To simplify the explanation, quadcopters operate on the same principle as helicopters, but with four separate motors and blades instead of two, allowing for greater maneuverability.

The history of quadcopters can be traced back to the late 19th century when multi-rotor aircrafts were used in a model balloon, propelled and steered by multiple engines. However, it wasn’t until the 1950s when a working prototype was created to study the effects of high altitude winds on helicopters. From then on, quadcopters have evolved significantly in their design, capabilities and usage. In recent years they have become increasingly popular for recreational purposes such as drones used for photography and are also being employed commercially in hazardous environments and industries such as search and rescue operations.

Though there has been some confusion between consumer drones (quadcopters) and remotely piloted aircraft systems (RPAS), these terms generally refer to two different types of technology – consumer drones are typically smaller scale devices while RPAS are used strategically in commercial settings where greater payloads may be required. As we enter into a future full of drone technology applications we will start to see the gap between both types narrow significantly; however understanding the main differences between quadcopters vs drones is key to understanding the history behind this technology.

Early History of Quadcopters

Quadcopters are a type of unmanned aerial vehicle (UAVs) that have four rotors. These vehicles were first developed in the early 1950s, but the technology didn’t become widely accepted until the mid-2000s. Since then, there has been an explosion in the popularity of quadcopters, as well as drones.

In this article, we will discuss the early history of quadcopters and how they have evolved to become the popular consumer drones they are today.

Early Development of RC Aircraft

The first radio-controlled (RC) aircraft was developed in the 1960s and since then, the design and evolution of RC aircraft has been a popular engineering challenge. The evolution of these devices eventually gave us multi-rotor craft, known as quadcopters, for their four rotors. These early models were bulky and lacked the modern features found in today’s consumer quadcopters, but they showed great promise as an efficient and effective aerial platform.

Much of the thanks for fine-tuning the design of these drones goes to T.T Henderson from England who created tethered drones for military uses during World War II. His work with electrically powered jets moved forward when he worked with model sized versions on behalf of hobbyists such as Francois Decaillet, creator of Fairey Monarch 04X helicopter with 4 engines that was the first to use ailerons on its blades. Unfortunately that model had safety and flying issues among other limitations so it wasn’t until 1969 when engineers Alan Pepper and Ogle Moore finally created a petrol engine powered quadcopter that could actually fly which they called ‘POGO’.

Later after improved designs it reached West Germany at Krämer Museum where students at Olvenstedt Technical University designed simple electronic Quadcopters in 1973, these saw massive adoption after proper research done by Dr. Dieter Schlüter into drone technology later making his design flying weight less than 2 kg, this standard Quadcopter is still used today with modifications made to increase operating range by adding wireless technology and dropping overall fly weight capacity by 30%.

Though various obstacles came in terms of safety required for operating RC copters due to FAA regulations only recently have manufacturers started producing larger consumer available commercial ready quadcopters in 2006 when Trend CT Models LTD released their Hornet model which became highly successful carving out an unprecedented market for quadcopter types in hobbyist usage providing people access to a tool valuable for surveillance, aerial cinematography amongst many other functions.

Introduction of Quadcopter Design

The quadcopter is a relatively new invention, though its concept and basic technology have been around since the mid-1950s. Quadcopters are powered vehicles that use four rotors to generate lift and propulsion. The four props provide stability, maneuverability, and control far greater than would two or one prop designs. This makes quadcopters an incredibly useful tool in many applications from aerial photo/video or surveillance to cargo transport.

The original concept for the quadcopter design dates back to around 1928 when French aircraft designer Henri Coanda proposed using four rotor airfoil/propeller combination planes for use in aerial photography. At this time, his ideas weren’t used but did set the stage for possible future development of the four-rotor technology. By 1960, it appeared that the four-rotor concept was becoming more viable as many different types of research took place on radio-controlled model helicopters and aircrafts utilizing multiple propellers.

A major breakthrough occurred in 2001 when Dr. Markus Kuhn invented an unmanned radio controlled helicopter named AscTec Hummingbird while working at German Aerospace Center in Oberpfaffenhofen, Germany. It was designed with eight rotors but five where redundant as a safety feature in case one out of eight rotors failed during flight operations including autonomous flight modes – a significant advancement for its time given that all existing aircraft before AscTec Hummingbird depended solely on human pilots with aeronautical skill rather than on artificial intelligence (AI).

In 2007, manufacturer KAM AIR FLIGHT created automated flight algorithms allowing successful maneuvers such as automatic takeoff and landing using only three out of the overall eight rotors found on their BREE 300XS multirotor Air Base Node UAV (Unmanned Aerial Vehicle). In 2011 Parrot AR Drone products made it onto consumer shelves—becoming widely available commercially—which allowed users to experiment with beginner friendly DIY quadcopters by attaching necessary pieces together by themselves with batteries required significantly smaller than those used on traditional aircrafts up to this point.

This led to the innovative drone technology we use today which has opened up countless possibilities especially when it comes to commercial applications such as military surveillance, delivery transport services and even recreational activities like FPV racing – harnessing speeds up 140 mph through remote control piloting!

quadcopter vs drone

Quadcopters and drones are often mistakenly used interchangeably, however, these two terms refer to different types of flying machines. The difference lies in their number of propellers, design, and purpose. Quadcopters are small, four-rotor aerial vehicles equipped with four rotors while drones are larger, more advanced, and have more than four rotors.

This article will explore the history of both quadcopters and drones and how they compare to each other.

Definition of Quadcopters

Quadcopters, also referred to as quadrotors, are multi-rotor helicopters that have four rotors to move in all directions. They are the go-to type of Unmanned Aerial Vehicles (UAVs) for use in a variety of industries because they can remain in the air for extended periods of time and travel quite long distances with increased stability and control.

The way quadcopters work is quite simple: two rotors rotate clockwise (CW) and two rotate counter-clockwise (CCW). The motors are programmed to adjust individually, according to the direction of flight, orientation and speed. This allows for a much greater range of movement than fixed wing aircrafts or traditional helicopters using single-axis flybars.

Quadcopters come in a wide range of shapes and sizes – from the tiny palm sized toy versions right up to large scale industrial drones powerful enough to lift significant loads – equipped with various mountings suitable for carrying out tasks such as filming or surveillance. With all their features they have become one of the fastest growing drone markets.

In contrast to Quadcopters, drones do not necessarily have four rotors: some can operate with three or more blades depending on their size and capacity. As a general rule of thumb though, most people just define any UAV with more than two blades as a drone as opposed to Quadcopter.

Definition of Drones

A drone is a type of Unmanned Aerial Vehicle (UAV), which is typically an aircraft flown by either a remote control or autonomously via onboard computers. The most common drones are quadcopters, which have four rotors and are powered either by gasoline or electricity. Drones come in different sizes and shapes and can be used for various purposes, from commercial applications to private hobbies.

Drones have become very popular in the industry today, being used for everything from delivering packages to filming movies. Its versatility has made it one of the most sought after devices for entrepreneurs, hobbyists, and manufacturers alike.

Drones come equipped with different tools depending on their specific use. Some common features include a camera for aerial photography; sensors and actuators for flight control; global positioning systems (GPS) to detect positional data; and autopilot software that enables the drone to carry out tasks autonomously.

The two major categories of drones are those that use fixed-wing technology – like airplanes do – which require considerable skill to operate safely, or those that utilize multi-rotor craft called quadcopters – hence the term ‘quadcopter vs drone’ – which are much easier to use but require more powerful propulsion systems to reach greater heights and speeds than fixed wing UAVs can manage. As technology advances, more advanced probes with more capabilities are being developed all the time.

Differences Between Quadcopters and Drones

Since they first appeared in the late 2000s, quadcopters and drones have been popular hobbies for tech-inclined individuals. But what is the difference between a quadcopter and a drone? The answer depends on how you want to define them.

A quadcopter is a specific type of drone. It is an unmanned aerial vehicle (UAV) with four rotors that enable it to take off and fly in any direction. Quadcopters are able to hover in place, flip, spin and make very tight turns thanks to their unique design. They also tend to be smaller than other types of drones as they lack the extra batteries required for heavier UAVs.

Drones, on the other hand, refer to a broad range of UAVs that are capable of performing automated aerial functions such as mapping, surveillance or photography/videography. Though they may contain multiple engines, they do not necessarily need four rotors like those found on quadcopters.

Other models may feature jet engines or large balloons instead. While quadcopters are used mostly for recreational purposes and consumer-level photography/videography projects, many companies rely upon heavy-duty drones capable of carrying additional payloads like sensors or cameras inside industrial machinery or construction sites which cannot be accessed by humans directly due to safety reasons.

Modern Quadcopters

Modern quadcopters have come a long way since their invention in the early 1960s. Quadcopters are now more popular than ever as they are used for a variety of applications, from photography to search and rescue operations.

In this section, we’ll look at the modern quadcopter and explore how it differs from its predecessor, the drone.

Uses of Quadcopters

Quadcopters have become increasingly popular in recent years due to their flexibility, affordability and the wealth of ways they can be used. From photography to recreation and transportation, to search and rescue operations, there are countless applications for quadcopters today.

  • Taking Photos & Videos: Quadcopter cameras have become increasingly affordable and capable of capturing stunning photos and videos from the sky. As a result, aerial photography has become much easier and more accessible to amateurs as well as professional photographers.
  • Live Video Streaming: Live video streaming can be achieved through quadcopters with specialized cameras attached to them. This allows users to reach a broader audience with live video streaming that’s provided in real-time.
  • Delivery Systems: Amazon is currently developing drone delivery systems for its Prime services, where small packages are delivered by unmanned aerial vehicles (UAVs). These UAVs could be quadcopters or other aircraft with multiple rotors for increased stability during flight processes.
  • Sports & Recreation: Many people enjoy recreational quadcopter flying for fun or competition. They are becoming increasingly common in sports competitions such as drone racing, which is gaining a lot of popularity all around the world. Additionally, 3D obstacle course competitions featuring custom-built drones have been gaining traction over the last few years.
  • Military Uses: Not all uses of UAVs have been restricted to commercial activities – militaries around the world employ drones both on land as well as in sea warfare operations too! Quadcopters are especially useful due to their better maneuverability in complex scenarios than larger drones at lower altitudes where traditional surveillance drones would not be able to see accurately or effectively collect data.
  • Search & Rescue: Being able to cover large distances swiftly, search and rescue units rely on quadcopters outfitted with high-definition cameras for reconnaissance operations such as examining dangerous areas like oil spills or damaged infrastructure after a natural disaster strikes.

Quadcopter Technology

Quadcopters, also known as quadrotors, have become a popular form of unmanned aerial vehicle technology over the past decade. First developed for military purposes, this type of aircraft uses four rotors to provide vertical lift and maneuverability. Unlike traditional fixed-wing aircraft which need forward motion to generate lift, quadcopters rely on the thrust from their engines to float freely in the air.

With this concept in mind, many enthusiasts have taken it upon themselves to build and operate homemade quadcopters for hobby purposes.

Modern quadcopter technology has greatly evolved over the years due to advances in understanding aeronautical structures such as rotor dynamics, thrust equations, gyroscopic stability and control systems. Developments in lightweight materials like carbon fiber and aluminum alloys have also increased the efficiency of these machines by allowing them to take off with decreased power consumption while still maintaining sufficient flight times.

More recently built electric motors produce greater thrust at smaller weights while onboard electronics provide autonomous systems that simplify piloting a quadcopter. This advancement has created much easier flying platforms along with improved safety features found on advanced models such as built-in return home functions and obstacle avoidance capabilities.

The increasing prevalence of quadcopters has raised some questions about the differences between these vehicles and what is commonly referred to as drones, which can typically be seen flying about in various applications including search and rescue operations or scientific research expeditions.

Essentially any device that can fly without an onboard pilot is considered a drone; however most drones are actually multirotor systems similar to those used by hobbyists today (e.g., octocopters). The main distinguishing factor between a drone and other unmanned aerial vehicles is its capability for autonomous flight (without direct human control). As drone technology continues to progress we are likely to see more interesting implementations emerging from entrepreneurs worldwide!


In conclusion, there are many factors to consider when deciding between a quadcopter and a drone for your application. Quadcopters can be more affordable, offer enhanced maneuverability and stability over long distances and are generally easier to control due to the four rotors providing lift. Drones can offer increased range, better aerial filming options with greater stability due to their heavier frame and provide higher speeds for racing or live streaming applications.

In terms of their history, quadcopters were first developed in 1930 by American aviator George de Bothezat who conceived of the idea as an alternative to traditional helicopters which relied on engines with complex transmission systems. In the late 80s and early 90s commercially produced quadcopters became available in toy form such as those used in video games like ‘Ace Combat’. It wasn’t until the mid 2000s that breakthroughs in sensor technology made affordable consumer-grade devices like consumer grade RC helicopters become available. The rest is history!
