Understanding Flybars on RC Helicopters

Understanding Flybars on RC Helicopters

A flybar is a vital component of radio-controlled (RC) helicopters responsible for flight stability and control. It acts as a balancing mechanism that helps keep the helicopter steady in the air while in-flight. A flybar is typically made up of a series of components, including the flybar paddles, flybar rods, flybar weights, and flybar control arms, that function together to give the helicopter its stability. The flybar is a significant component of traditional RC helicopters, but the technology is becoming less popular in modern times with the advent of flybarless systems. However, despite being phased out, traditional flybars are still widely used and are fundamental in providing stability while in the air. Without the flybar, a helicopter’s flight control would be severely impacted, making it difficult and potentially dangerous to fly. Therefore, understanding the flybar and its function is crucial for any RC helicopter pilot.

History of Flybar Technology

The first radio-controlled helicopters didn’t use flybars, relying instead on a mechanical system to stabilize it. RC helicopters began to incorporate flybar technology as early as the 1970s, dramatically improving their stability in the air. As helicopters become more complex and flybars became more sophisticated, they became even more vital in providing the necessary stability for flight control.

Types of Flybars

There are two main types of flybars:

  • Single-axis, which only stabilize the helicopter’s side-to-side movement
  • Mutli-axis, which stabilize the helicopter’s side-to-side, up-and-down, and front-to-back movements

Traditionally, flybars have been the go-to stabilization system for most RC helicopters. However, with advances in technology, they are now being replaced by flybarless systems, which offer increased stability, faster response time, and less weight. At RC hobby stores, flyers can purchase a flybarless conversion kit that allows them to upgrade their traditional RC helicopter to a flybarless system.

Who made Flybar?

Flybar is a brand that produces pogo sticks for children and adults. The company was founded in 1918 by George Hansburg and has remained in the family for four generations. Today, Flybar is run by Bruce Hansburg, the great-grandson of the founder.

Components of a Flybar

A flybar is composed of several critical components that work together to stabilize the helicopter in flight. These include:

  • Main Rotor Blades – The main source of lift for the helicopter.
  • Flybar Paddles – Connected to the flybar itself, their weight counteracts any sudden movements of the helicopter caused by gusts of wind or user input.
  • Control Rods – Connect the flybar to the rotor head in order to simulate the movement of the helicopter.
  • Swashplate – Adjusts the angle of the rotor blades to influence the helicopter’s movement.

Interestingly, the original flybar technology used simple weights to stabilize the helicopter. Modern flybars are much more complicated, utilizing gyroscopes, electronic sensors, and computer-controlled systems to provide accurate and precise stabilization. Flybars are necessary but complex components of RC helicopters, and it’s essential to understand their function and maintenance to prevent accidents during flight.

How does an RC helicopter flybar work?

An RC helicopter flybar is a crucial part of a helicopter’s control system. Here’s how it works:

  • The flybar rotates with the rotor blades and provides additional stability during flight.
  • It helps to counteract any sudden movements or torque changes by acting as a gyroscopic stabilizer.
  • As the helicopter tilts forward or back, the flybar moves in the opposite direction, helping to keep the helicopter level.

Overall, the flybar is an important component in the flying experience of an RC helicopter. If you’re looking to purchase an RC helicopter or related accessories, check out websites such as Horizon Hobby or AMain Hobbies for a wide selection.

Types of Flybars

There are two primary types of flybars utilized in modern RC helicopters: traditional flybars and flybarless systems. Here are the defining characteristics of each:

Traditional Flybars

  • Uses a flybar with weights to provide stability
  • Requires less complicated electronics
  • Generally less expensive and simpler to maintain
  • Can be less precise than flybarless systems
  • Can be more susceptible to wind gusts

Flybarless Systems

  • Relies on onboard electronics for stability and control
  • More precise and customizable than traditional flybars
  • Can be more expensive and complicated to maintain
  • Can provide a smoother and more realistic helicopter flying experience
  • Usually more effective in windy conditions

It’s important to note that individual preferences and flying experience may determine which type of flybar works best for you. Some RC helicopter enthusiasts enjoy the customization and precision of flybarless systems, while others prefer the simplicity and ease of use of traditional flybars. Regardless of which system you choose, regular maintenance and checks for wear and tear are essential to ensure proper functioning and safety during flight.

What is the difference between Flybarless and Flybar heli?

Flybar and Flybarless are two different types of helicopters. The difference lies in the mechanics of how they are controlled. Here’s a breakdown of the main differences:

  • Flybar Helicopters:
    • Uses a flybar to stabilize the helicopter while in flight
    • Can be more stable in windy conditions
    • May require more maintenance due to more moving parts
    • Usually less expensive than flybarless helicopters
  • Flybarless Helicopters:
    • Utilizes electronic systems instead of a flybar for stabilization
    • Offers quicker and more responsive control
    • Requires less maintenance due to fewer moving parts
    • Higher initial cost but can save money in the long term

Both types have their benefits and drawbacks, so it ultimately comes down to personal preference and flying style. Some popular brands that offer both flybar and flybarless helicopters include Blade, Align, and SAB Helicopters.

Flybarless Systems

Flybarless systems have become increasingly popular among RC helicopter enthusiasts due to their advanced technology and precision. Here are some key features and benefits of flybarless systems:

Gyroscopic sensors

– Integrated sensors provide precise readings of the helicopter’s orientation and motion
– Allows for quicker and more accurate adjustments to maintain stability
– Improves overall flying experience, especially for more challenging maneuvers


– Eliminates the need for a complex mechanical flybar and its associated parts
– Fewer moving parts means less maintenance and repair
– Reduces overall weight of the helicopter, improving flight performance


– Increased adjustability allows for customized flight experiences
– Flybarless systems can be fine-tuned for specific types of flying, such as 3D aerobatics or smooth, stable hovering
– Different brands and models offer unique settings, allowing for greater customization options

If you’re interested in upgrading to a flybarless system, it’s worth exploring different brands and models to determine which one suits your flying style and budget. Online RC forums and websites, as well as RC hobby shops, can provide valuable information and guidance in making this decision. Regular maintenance and checks for wear and tear are still important with flybarless systems to ensure proper functioning and safety during flight.

What is the difference between flybar and flybarless?

  • Flybar helicopters have a paddle-like structure extending from the rotor head called flybar, which helps to stabilize the helicopter during flight.
  • Flybarless helicopters, on the other hand, do not have a flybar but depend on electronic stabilization systems to maintain flight stability.
  • Flybarless helicopters tend to be more agile and responsive than flybar helicopters.
  • Flybarless technology is commonly found in high-performance or 3D helicopters.
