Types of Large RC Boat Motors
There are several different types of large RC boat motors, each with their own unique characteristics that make them suitable for specific boats and purposes. Below are some of the most common types available in the market today:
- Brushed Motors: These motors are the most basic type and often found in small and lightweight RC boats. They are simple, reliable, and easy to maintain. However, they are less efficient, have lower power output, and tend to wear out faster than other types.
- Brushless Motors: These motors use electronic speed controllers to operate and are more advanced than brushed motors. They are known for their efficiency, power, and longer lifespan. Furthermore, they require less maintenance and have a smoother operation. However, they are more expensive than brushed motors and require more technical knowledge to operate.
- Inrunner Motors: These motors are characterized by their high speeds and acceleration, making them suitable for speedboats and racing boats. They have a compact size and operate at higher RPMs than other types, making them ideal for boats that require high speeds.
- Outrunner Motors: These motors are known for their high torque and efficiency. They are ideal for larger and heavier RC boats that require more power to operate. They spin slower than inrunner motors, but with higher torque, making them perfect for boats that require more turning power.
When choosing the right type of motor for your large RC boat, it is essential to consider the boat’s size, weight, and intended use. Online stores such as HobbyKing, Horizon Hobby, and Tower Hobbies offer a wide range of motors suitable for different types of boats. They also provide detailed specifications, reviews, and customer support to help you find the perfect motor for your RC boat.
How to choose a motor for a RC boat?
When choosing a motor for your RC boat, it’s essential to consider the size and weight of your boat, as well as the intended use and desired speed. A brushless motor will typically provide more speed and power, while a brushed motor is generally more affordable. When selecting a motor, look for one that matches the voltage of your battery and has an appropriate Kv rating. It’s also crucial to consider the cooling system to prevent overheating of the motor. You can find a wide selection of RC boat motors on websites such as Amazon or HobbyKing.
Large RC boat motors come in different types and sizes. For bigger and heavier boats, brushless motors are often preferred because of their efficiency and power. However, for smaller and lightweight boats, brushed motors are the go-to option.
Brushed motors are the most basic type of motors and are easy to use. They are also cheaper and widely available compared to brushless motors. However, they have some disadvantages. They are less efficient and produce less power than brushless motors. They also have a higher chance of wear and tear and can be noisy and produce heat.
Despite their disadvantages, brushed motors are still widely used in RC boating and have been instrumental in its development. They are ideal for beginners and smaller boats as they are simple and require minimal maintenance. They can also be easily replaced or upgraded.
If you are interested in purchasing brushed motors for your large RC boats, online stores such as Amazon and eBay offer a wide range of options. Some of the most popular brushed motors available on Amazon include the Traxxas Titan 550, the Tamiya 540-J, and the Associated Electrics Reedy Radon 2. Prices range from $18.99 to $22.79.
Overall, while brushed motors may have their drawbacks, they are still a viable option for large RC boats and can be a cost-effective solution for those starting out in the hobby.
What are the basics of a brushed motor?
Brushed DC motors have four main components: a stator, a rotor, a commutator and brushes. The rotor contains coils of wire wrapped around a ferrous metal core and is powered by brushes. For more detailed information and illustrations, visit websites such as HowStuffWorks or manufacturers’ websites like Baldor’s.
Brushless motors are more advanced than brushed motors and are used in larger and more powerful RC boats. Here are some of the advantages and disadvantages of using brushless motors:
- Pros:
- Higher efficiency and power output than brushed motors
- Longer lifespan and less wear and tear
- Less heat and noise production
- Greater speed control and responsiveness
- Suitable for larger and more advanced boats
- Cons:
- More expensive than brushed motors
- Require specialized knowledge and equipment for maintenance
- Can be more complex to use and set up
Brushless motors work by using electronic signals from the controller to switch the magnetic field of the rotor, causing it to rotate. This eliminates the need for brushes and makes brushless motors more efficient and reliable.
If you’re interested in purchasing brushless motors for your large RC boats, there are many online stores and brands that offer a wide range of options. Some popular brushless motor brands include:
- Castle Creations
- Traxxas
- Turnigy
- Hobbyking
The table below shows some of the most popular brushless motors available on Amazon:
| Brand | Model | Power | Price |
|---|---|---|---|
| Hobbysky | Waterproof Brushless Motor | 2200KV | $36.99 |
| Tamiya | Super Stock Brushless Motor | 10.5T | $73.99 |
| Castle Creations | Sidewinder SCT Brushless Motor | 1410-3800KV | $115.00 |
Why is a brushless motor better?
Brushless motors are better because they are more efficient than brushed motors. According to Consumer Reports, brushless motors are more energy-efficient than brushed motors, often running on battery power for up to 50 percent longer. They have a longer battery life since they don’t contain brushes that lose energy to friction. Additionally, many models can run for hours.
Inrunner Motors
Inrunner motors are another type of motor that is commonly used in large RC boats, especially those that require high speeds and acceleration. Here are some of the pros and cons of using inrunner motors:
- Pros:
- High-speed operation
- More efficient than brushed motors
- Suitable for boats that require high speeds and acceleration
- Lightweight and easy to install
- Cons:
- Not as powerful as brushless or outrunner motors
- Can be more expensive than brushed motors
- Less torque than outrunner motors
Inrunner motors get their name from the fact that their rotor is located on the inside of the motor’s case. They are typically smaller and more lightweight than other motor types, which makes them ideal for high-speed boats. Inrunner motors are also popular in racing boats because of their ability to deliver fast, responsive performance.
If you’re interested in purchasing inrunner motors for your large RC boats, there are several online stores and brands that offer a wide range of options. Some popular inrunner motor brands include:
- Leopard
- Cooling Sky
- DYS

| DYS | D4023 | 1100KV | $109.99 |
| Cooling Sky | High-Speed 3042 | 1000KV | $58.90 |
What is the difference between inrunner and outrunner motors?
The main difference between inrunner and outrunner motors is the location of the rotor in relation to the stator. In inrunner motors, the rotor is located on the inside of the stator, while in outrunner motors, the rotor is located on the outside of the stator. Outrunner motors are known to produce more torque for the same build volume compared to inrunner motors. Magnetic Innovations is a company that specializes in outrunner motors, offering high-quality products in this typology.
Outrunner Motors
Outrunner motors are a popular choice for large RC boats that require high torque and efficiency. These motors have their rotor on the outside of the motor’s case and can provide more power than inrunner and brushed motors. Here are some of the advantages and disadvantages of using outrunner motors:
- Advantages:
- Powerful and efficient
- Provide high torque
- Suitable for boats that require high power
- Larger and more durable than other motor types
- Disadvantages:
- Less efficient than inrunner and brushless motors
- Can be heavier and more difficult to install
- May generate more heat than other motor types
Outrunner motors are a popular choice for large RC boats that require more power and torque than other motor types can provide. They are typically larger and more durable than inrunner and brushed motors, making them ideal for bigger boats. Outrunner motors are also efficient at generating and maintaining high levels of torque, which is important for boats that require a lot of power to operate.
If you’re in the market for outrunner motors for your large RC boat, there are many online stores and brands that offer a variety of options. Some popular outrunner motor brands include:
