Gas RC Helicopter: A Guide for Beginners

A Gas RC helicopter is an exciting and fascinating toy for many aviation enthusiasts. Flying an RC helicopter provides a thrilling experience for many hobbyists due to the mastery, skill, and control demonstrated when taking flight. Gas RC helicopters are more demanding compared to their electric counterpart. They require a mixture of fuel and oil, necessary for the effective operation of the engine. But due to their complex design and powerful engines, they are still preferred by enthusiasts who enjoy tinkering with, customizing, and building their RC aircraft. The challenge of maintaining and flying a gas RC helicopter is an enjoyable and rewarding experience that requires lots of patience, skill, and dedication. It is essential to have a good understanding of the components, types, prices, builds, maintenance, and the necessary precautions to take when flying a gas RC helicopter.

Components of the Gas RC Helicopter

The gas RC helicopter engine is made up of various components working together to keep it in flight. Below are the essential parts of the gas RC helicopter engine:

  • Carburetor: This component mixes the fuel with air before it enters the engine.
  • Ignition: It is responsible for starting and maintaining combustion in the engine.
  • Piston: It moves up and down courtesy of the crankshaft, transferring power to it.
  • Cylinder: These components hold the piston, allowing it to move in an up-and-down motion. Additionally, the cylinder helps the piston create compression before combustion begins.
  • Crankshaft: The crankshaft rotates as the piston moves up and down, supplying energy to the rotor blades to maintain the helicopter’s flight.

Having a good understanding of the mechanical parts of your gas RC helicopter will help you maintain it to ensure effective performance. You can also check out websites such as Amazon, Walmart or HobbyKing to find high-quality components for your gas RC helicopter.

What are the parts of a RC helicopter?

The main parts of a RC helicopter are the rotor hub, main rotor, swash plate, tail servo, tail boom, tail rotor, and landing skid. These parts are responsible for controlling the helicopter’s movements and stability. To learn more about RC helicopters, you can visit websites such as Horizon Hobby ( or Blade Helis ( which offer a variety of products and resources for enthusiasts.

Types of Gas RC Helicopter

If you’re interested in purchasing a gas RC helicopter, it’s essential to know the different types available. The two primary types are Nitro and Petrol:

  • Nitro RC Helicopters: These are more common than petrol RC helicopters and are powered by a glow-plug. They tend to be smaller in size and have a shorter flight time. However, they are affordable and can be easily upgraded.
  • Petrol RC Helicopters: These helicopters run on gasoline and are larger in size with longer flight times than nitro RC helicopters. Due to their size, they require more space to fly. They also tend to be more expensive.

Below is a table that shows a side-by-side comparison of the Nitro and Petrol gas RC helicopters.

Nitro RC Helicopter Petrol RC Helicopter
Power Source Glow-plug Gasoline
Size Smaller Larger
Flight Time Shorter Longer
Upgrade Options Easy Limited
Price Affordable Expensive

Keep in mind that regardless of the type you choose, it’s essential to buy from a reputable dealer or website that carries high-quality gas RC helicopters. By purchasing from a trusted source, you can ensure that the helicopter is safe and reliable. Some popular brands of gas RC helicopters include Horizon Hobby, Align, and TechOne.

What kind of fuel does a RC helicopter use?

Remote control helicopters use different types of fuel as a power source. The most common power sources are glow fuel (nitromethane-methanol), electric batteries, gasoline (petrol), and turbine engines. In the past, glow fuel helicopters were the most common type produced for 40 years. No website or product is required for the answer.

Choosing the Right Gas RC Helicopter

When choosing a gas RC helicopter, there are a few things to consider before making a purchase. Here are some factors to keep in mind:

  • Build Quality: The frame is essential to handle the power of the engine. A metal frame is typically sturdier and provides better lift.
  • Engine Quality: High-quality engines and electronics are necessary for durability and efficiency.
  • Material: Carbon-fibre is a popular choice for gas RC helicopter blades as it’s lightweight and strong. Some manufacturers also use aluminum and plastic materials.
  • Price: Gas RC helicopters can range from a few hundred to a few thousand dollars, so it’s essential to figure out a budget before buying.
  • Brand Reputation: Choose a gas RC helicopter brand that has an excellent reputation for quality and customer service. Look for online reviews from other users to help with your decision-making process.
  • Dealer: As mentioned earlier, buying from a reputable dealer or website is crucial. Ensure that the vendor sells legitimate products and offers customer support in case of any issues.

Keep in mind that the right gas RC helicopter for you will depend on your preferences, budget, and skill level. Take the time to research and understand the features of each model before making a purchase.

How to choose a motor for RC helicopter?

When choosing a motor for your RC helicopter, there are several factors to consider such as the size and weight of the helicopter, the desired flight characteristics, and the power requirements. It is essential to choose a motor that can provide enough power for the helicopter without being too heavy or too weak. You should also consider the voltage, current, and RPM rating of the motor. In addition, it is crucial to choose a reputable and reliable brand of motor to ensure that it can withstand the stresses of RC helicopter flight. You can find a wide variety of motors for RC helicopters from online retailers such as HobbyKing, Banggood, or Amazon.

Tips for Flying the Gas RC Helicopter

Flying a gas RC helicopter takes patience, practice, and an understanding of wind conditions. Here are some tips for successful flights:

  • Flying Area: Choose a large open field or park to fly your gas RC helicopter. Make sure that there are no trees, buildings, or people close by, and it’s far away from power lines or other hazards.
  • Wind: Avoid flying in windy conditions as it can lead to instability in the aircraft. Check the weather forecast before taking your helicopter for a spin.
  • Fuel Balance: Ensure that you have the correct fuel-to-oil ratio and that the tank is full before flying. Check the balance regularly to prevent engine damage.
  • Blades: Always check the blades before flight to make sure that they are in good condition, not bent, and tightly attached. Replace blades if necessary.
  • Orientation: When flying, keep an eye on the orientation of the helicopter. It can be challenging to know the front from the back of the aircraft when it’s far away, so consider adding bright colors to make it more visible.
  • Practice: Practice regularly to improve your flying skills, and consider taking lessons from a professional if you’re just starting.

Remember, safety should always be your top priority while operating a gas RC helicopter. Always follow the manufacturer’s safety guidelines and avoid flying too close to other people or objects.

How do you land a RC helicopter?

To land a RC helicopter, you should start by reducing the altitude and speed, and slowly bring it down to the ground until it touches down gently. You can also consider practicing landing on a landing pad or a flat surface to improve your skill. A helpful resource for learning how to land a RC helicopter is a video tutorial on YouTube by ‘RC Help’ titled “How to Land a RC Helicopter Like a PRO!”. This video provides step-by-step instructions and visual examples to guide you through the process.

Maintenance of Gas RC Helicopter

To keep your gas RC helicopter in top condition, regular maintenance is key. Here are some maintenance tasks to perform:
