It’s important to select the appropriate power system based on your intended use and experience level. For beginners, electric motors may be a better option due to their ease of use and low maintenance requirements. However, experienced pilots may prefer the power and speed of internal combustion engines. Hybrid systems can also provide some advantages, but they may require more knowledge and investment.

Some popular websites for purchasing RC helicopter products and accessories include Horizon Hobby, HeliDirect, and RC Planet. Additionally, some manufacturers offer their own line of power systems specifically tailored for their RC helicopter models, such as the Align RCE-BL1050KV Brushless Motor for the Align T-Rex 700E DFC Helicopter.

How are helicopters powered?

Helicopters are powered by engines that drive their rotors which provide lift and allow them to stay aloft. Here are some common types of engines used in helicopters:

  • Turboshaft Engines: These engines are commonly used in helicopters and provide the necessary power to the rotors. They are lightweight and have a high power-to-weight ratio.
  • Piston Engines: These engines are similar to those used in cars and planes and provide power to the rotors through a transmission and driveshaft.

Some popular helicopter manufacturers include Airbus, Bell Helicopter, and Sikorsky. More information about helicopter engines and manufacturers can be found on their respective websites.

The design and construction of the 700 size RC helicopter largely determines its weight, durability, and flight performance. Here are some things to keep in mind:


  • Carbon fiber and aluminum are popular materials used in the frame and rotor blades for their strength and light weight.
  • Plastic or composite materials may be used in non-structural parts such as the canopy or landing gear.

Flybar vs. Flybarless:

  • A flybar is a horizontal rod that runs across the rotor blades and is used to stabilize the helicopter in flight.
  • Flybarless systems use electronic stabilization technology instead, which eliminates the need for a flybar and can improve flight performance.
  • Flybarless systems can also reduce weight and complexity, but may require more experience to set up and tune properly.

Blade Configuration:

  • The 700 size RC helicopter can have two, three, or four rotor blades.
  • Two blades generally provide more speed and agility, while three or four blades offer more stability and lift capacity.
  • The choice depends on the intended use and the pilot’s preferences.

When considering purchasing a 700 size RC helicopter, it’s important to check the manufacturer’s specifications and user reviews to ensure the quality of the materials and construction. Some popular websites for purchasing RC helicopter products and accessories include Horizon Hobby, HeliDirect, and RC Planet. Additionally, some manufacturers offer their own line of parts and upgrades specifically tailored for their RC helicopter models, such as the Align 700L Dominator 700mm Carbon Fiber Blade Set.

How are RC helicopters sized?

RC helicopters are typically sized based on the length of their main rotor blade. The length of the blade is measured from the center of the rotor to its tip and is usually given in inches or millimeters. Larger rotors generally result in larger helicopters with greater stability and lifting capacity.

Some common sizes for RC helicopters include:

  • Micro helicopters: 100mm-200mm rotor diameter
  • Mini helicopters: 200mm-300mm rotor diameter
  • Medium helicopters: 300mm-400mm rotor diameter
  • Large helicopters: 400mm-500mm rotor diameter

When choosing a size for your RC helicopter, it’s important to consider factors such as where you’ll be flying it, what kind of maneuvers you want to perform, and your skill level as an RC pilot.

For those looking to buy an RC helicopter, websites like Horizon Hobby and Tower Hobbies offer a wide variety of options in multiple sizes.
