The Beginners Guide To RC Helicopters
RC helicopters, also known as remote-control helicopters or radio-controlled helicopters, are miniature versions of real helicopters that can be operated using a handheld remote control.
They are increasingly popular amongst hobbyists and enthusiasts, who enjoy flying and controlling their model aircraft, often at RC helicopter shows, events and competitions.
Getting started with RC helicopters can be a bit overwhelming, especially if you’re new to the world of RC altogether. Luckily, this guide is here to help you get to grips with all things RC helicopters, as well as offer some general insight into the RC world in general.
What exactly are RC helicopters?
RC helicopters are captivating pieces of equipment that bring the joy of aviation into the hands of hobbyists and enthusiasts alike. These miniature flying machines offer an exhilarating experience as they take to the skies with precision and grace.
At the heart of an RC helicopter lies a remarkable combination of mechanics and technology. These intricately designed miniature aircrafts generally consist of a few key components, including a main rotor, tail rotor, fuselage, and their electronic controls. The main rotor, typically consisting of two or more blades, generates the lift necessary for flight, as well as provides control over the helicopter’s movement. The tail rotor serves to counteract the spin created by the main rotor, creating stability and allowing precise directional control.
Controlling an RC helicopter is a skill that requires practice and patience in the beginning. Operators use a handheld remote control transmitter that’s equipped with joysticks, buttons, and often switches to control and manipulate the helicopter’s movements. These inputs transmit signals to the helicopter’s onboard receiver, which then activates motors and servos to adjust rotor speeds and angles accordingly. With mastery, pilots can navigate their RC helicopters through a multitude of manoeuvres, including ascending, descending, turning, hovering, and even performing acrobatic stunts.
What are the different types of RC helicopter?
There are several different types of RC helicopters, with each type having different characteristics and uses.
Coaxial RC Helicopters
These helicopters have two sets of main rotor blades that spin in opposite directions. The counter-rotating blades provide increased stability and easier control, making them ideal for beginners and indoor flying.
Single-Rotor Fixed-Pitch RC Helicopters
These helicopters have one main rotor blade and an adjustable pitch angle. They are more manoeuvrable than coaxial helicopters, but require more skill to fly. They are typically used for outdoor flying and can perform various aerobatic manoeuvres with ease.
Collective-Pitch RC Helicopters
These helicopters have a single main rotor blade, but unlike fixed-pitch helicopters, the pitch angle of the blades can be adjusted. This allows for more advanced manoeuvrability, including inverted flight options and 3D aerobatics. Collective-pitch helicopters are often preferred by experienced pilots.
Scale RC Helicopters
Scale helicopters are designed to replicate real-life full-size helicopters in appearance and functionality, meaning that they usually feature detailed exteriors and realistic flight characteristics. Scale helicopters are popular amongst hobbyists and collectors alike.
Micro RC Helicopters
These helicopters are extremely small and lightweight, typically measuring only a few inches in length. Micro RC helicopters are designed for indoor flying and are ideal for practicing flying skills in confined spaces.
Gas-Powered RC Helicopters
Unlike electric-powered helicopters, gas-powered helicopters use internal combustion engines for propulsion. They offer longer flight times and can achieve higher speeds and greater lifting capabilities. Gas-powered helicopters require more maintenance and tuning, but are preferred by some enthusiasts.
Recently, gas-powered RC helicopters have taken a step back in terms of popularity with everyday hobbyists, in the same way that electric vehicles have been increasing in popularity over gas vehicles over the past few years.
FPV (First-Person View) RC Helicopters
FPV helicopters are equipped with cameras so that they provide a live video feed to the pilot, allowing them to fly the helicopter from a first-person perspective using a video headset or monitor. This immersive experience is popular among FPV racing enthusiasts.
Autonomous RC Helicopters
These helicopters are equipped with advanced sensors, GPS systems, and flight controllers that enable autonomous flight and various intelligent features. They can perform tasks such as waypoint navigation, follow-me mode, and automated flight patterns.
It’s important to note that each type of RC helicopter has its own set of advantages, disadvantages, and skill requirements. It’s crucial to choose a helicopter that matches your skill level and flying preferences to have an enjoyable and safe flying experience.
How do people use RC helicopters?
RC helicopters are used for many different purposes and activities, catering to both recreational and professional wants and needs.
Hobby and recreation
Many people around the world enjoy flying RC helicopters as a hobby/recreational activity. Whether flying in parks, open fields, or designated RC flying areas, enthusiasts find joy in piloting the helicopters, practicing manoeuvres, and exploring their capabilities of an RC helicopter. It can be a source of relaxation, fun, and a way to connect with like-minded individuals. It can also encourage families to spend time together, and encourages many to enjoy time out of the house.
Aerial Photography and Videography
RC helicopters equipped with cameras, such as GoPro’s or other specialist cameras, are often used to capture aerial photographs and videos. These helicopters provide a unique perspective, allowing photographers and filmmakers to capture stunning aerial shots for personal use or professional projects, such as weddings, real estate, or cinematography.
Racing and Competitions
RC helicopter racing has gained a tonne of popularity recently as a competitive sport. Participants compete against each other to navigate a predefined course, showcasing their piloting skills and manoeuvrability. This aspect often involves customised RC helicopters that are designed for speed and agility in particular.
Skilled RC helicopter pilots often perform aerobatic displays at air shows and events. These captivating demonstrations showcase intricate manoeuvres, flips, summersaults, and other impressive aerial stunts, entertaining spectators.
What are the first steps beginners need to take to start their journey with RC helicopters?
When you’re just starting out with using RC helicopters for the first time, it’s really important to start with the correct equipment and a positive approach. Taking a look at the above list of types of RC helicopter is crucial, as it’s wise to choose a beginner-friendly model such as the coaxial or fixed-pitch helicopters, both of which offer stability and are easier to control.
Once you have your RC helicopter, find an open and spacious area, preferably with minimal wind, to practice. Start by familiarizing yourself with the basic controls, and with gentle and slow movements, gradually building on your skills and confidence.
Consider joining a local RC helicopter club or online communities to learn from experienced hobbyists who can provide guidance, tips, and tricks. When you’re first starting out, it can be really helpful to have a friend or more-experienced pilot alongside you to offer you support and advice.
Regular practice, patience, and a willingness to learn from mistakes will really help beginners to develop their skills and enjoy the thrilling experience of flying RC helicopters.
