Here’s What You Need For Building An RC Boat (Tips & FAQs)

RC Boat enthusiasts tend to move from pre-made boats to self-made ones. It gives them the freedom to choose between customizations and materials. As challenging as it appears, it is possible to create RC boats yourself, from simple to complex models. If you’re planning on making your own, you must be wondering what you need to make it.

Building an RC boat requires some necessary components and a handy tool set. There are 7 main components needed to create the engine and the vessel. A battery charger and remote controller are required to complete the set. You can choose between BYOB (Bring Your Own Boat) kits or building a DIY boat from scratch. 

Seeing the kind of RC boats enthusiasts and hobbyists can create is impressive. Based on first impressions, it can seem like a challenging task, but you can build your own RC boat too! This article will summarize all the components needed for an RC boat and weigh the better way for you to make one. 

9 Essential Parts You Need To Build Your RC Boat

Whether you’re using a Build Your Own Boat (BYOB) kit or building from scratch, most components and requirements for the process are similar. 

Note: Unless you’re personally customizing your boat, it should come out looking and working the same way as any other commercially bought RC boat.

The components mentioned below are what you need to source if you’re going to DIY your RC boat. These parts will already be inside if you’re purchasing a BYOB kit. 

Depending on the company and size of the kit, you can choose between a simple or complicated boat model.

For RC boats, parts can be divided into internal and external components. Each piece and its function are explained below:

1. Motor

The central power system in an RC boat is the motor. It is available in two types, brushed and brushless. 

See my article for the best RC boat brushless motors and what to consider when buying.

A brushed motor is cheaper but relatively slower. Whereas brushless motors are in different price ranges and provide the most speed. 

You should choose your motor based on who will use the boat, where you will use it, and how fast you’d like your boat to go.

2. Servo

The servo is the internal component responsible for balancing and steering the boat. 

It is present with the other electronic components inside the hull. The servo works in sync with the transmitter, carrying out the movements. 

You can find servos in any shape or size to fit your boat. 

3. Rechargeable Batteries

The rechargeable battery is present onboard the RC boat. You should carefully consider what type of battery you should use because each battery has a different performance. 

The most common ones used are Ni-MH and Lithium-Polymer batteries. Lithium-Polymer batteries provide consistency throughout the run-time, while Ni-MH ones don’t. 

4. Body (Bottom, Hatch, and Hull)

The body of an RC boat includes 3 sections. 

The lower half is the bottom area submerged underwater. All the electronic components are contained in the hull region. Lastly, the waterproof top hatch protects the components and shuts the hull. 

Note: When deciding on the size of the boat, you should closely consider the measurements for each body part.

5. Propeller

The drive system of the boat is the propeller. 

The motor provides electrical energy, through which the propeller spins and creates a thrust. Based on the efficiency and force of the thrust, the boat speed is determined.

Propellers come in many blade shapes, materials and sizes. You should buy your propellor based on the total length of the boat and the number of propellers you’ll use.

And remember that when it comes to selecting the perfect propeller for your RC boat, size and shape are also vital. Wrong prop measurements can lead to decreased performance along with other issues. That’s why I’ve put together a comprehensive guide on how to measure an RC boat prop.

6. Rudder

The steering system in the boat is the rudder. 

There is only one rudder present on each RC boat. When you change directions on the remote control, it sends the command to the rudder, which moves left and right. 

The rudder’s control allows you to maneuver high-speed RC boats without having them flip over.

7.  Battery Charger

There are two types of chargers for your RC boat’s battery, a normal and a fast charger. 

A standard charger can take up to 5-8 hours to charge your RC boat, while a fast charger can at least cut the time by half.  

Note: You should avoid using random changers for your boat, as that can damage the battery. Always keep a check on the charger in case it overheats.

8. Radio System (Transmitter/Receiver)

The radio system is the Radio Frequency (RF) for both the transmitter and receiver. It is responsible for sending the remote control command to the boat. 

Note: The older frequencies of 27MHz and 75MHz, have been replaced by 2.4GHz

By using 2.4GHz, you’ll experience less conflict and interference with other remote controls and radio sources nearby.

9. Remote Controller

A controller is what gives the RC boat commands. 

Typically, the controller doesn’t have to be assembled, so it doesn’t count as a component. However, if you’re creating your boat from scratch, you’ll need to buy one and ensure it works on the frequency you need. 

Extra Tip: You can also add features such as a battery and range alarms to keep your boat from getting lost.

What You Should Know While Making an RC Boat?

Beyond the RC boat parts and assembly process, there are other things to remember before you start. 

Make sure you have all the tools necessary for the building process, know all regulations, and put safety first.

Tools Needed For Assembly of Your RC Boat

Making an RC boat may look complicated, but it is simple if you break it into steps. 

If you’re using a BYOB kit, you should read and understand the manual before you start. Make sure to carefully follow each step written. 

If you’re doing DIY from scratch, find a simple step-by-step tutorial on youtube to learn from.

Before working on your RC boat, ensure you’re well equipped. Have a workspace, preferably a workbench, to spread your components, tools, and manual. Depending on the complexity of your model, have glue, screwdrivers, pliers, and tape with you.

You could buy a complete toolset (Amazon link), to make your own building kit.

Its also essential to have a selection of of different sized clamps. You will will need these to hold materials after they’ve been stuck together to dry. This clamp set (Amazon link) is ideal.

Rules For Building And Using Your RC Boat

Some official bodies can help teach you what rules and regulations apply to your RC boat. You would have to search for them according to your area or country. However, some regulations are used across the board. You should respect these rules when you choose to take up RC boats as a hobby.

The size requirement, for instance, is universal, and your boat should stay within the 24”-36” limit. Creating a larger boat will limit the areas you can use and make it harder for you to enjoy. Additionally, the size limit is applied because the boat you create shouldn’t be used for passengers, whether animals or humans.

You should ensure that your engine is safe to use. Speed will obviously be a priority when creating your RC boat, but it shouldn’t put you at risk. Make sure you have an appropriate engine for your boat size, couples well with the battery, and has a cooling system. Engine overheating is a potential danger you should be careful about.

There are strict rules regarding Fuel Emissions and Oil or Fuel Leaks. So as an owner of a Gas or Nitro powered RC boat, you should take adequate precautionary steps. Don’t overflow the fuel tanks, and avoid using faulty RC boats. 

Due to the environmental threat, most companies consider Electric RC boats safer and prefer to produce them.

Safety Precautions

Being safe throughout the process must be your priority.

For anyone under 16, adult supervision is advised. Using a BYOB kit is simple, and most are designed for children 14 years and up. It is safe, but inexperienced children can get hurt or make mistakes. 

DIY boat projects are only recommended for pros or those with long-term experience with wood, electronics, and building objects. 

Be careful when using tools. Avoid substituting simple tools with other gadgets. If your screwdriver works fine, you don’t need to use a drill to work faster. 

You should also avoid using random items to get the job done. For example, school craft glue is not a trustable adhesive and shouldn’t be used on internal or external components.

Don’t try to experiment with electric components. Please listen to the safety guidelines mentioned in the manual and avoid using shortcuts. When dealing with batteries, motors, and their wirings, you should use a trusted source to follow. You can ask a technician or electrician for advice or help if it’s too complicated for you.
