RC Boat Kits: Types, Makers and How to Choose Your First Build
RC boat kits range from laser-cut plywood racing hulls (such as ZippKits) and fibreglass hydroplanes and outriggers to detailed scale models of tugs, lifeboats and warships, and sailboat kits for classes like the IOM and RG65. A kit gives you the hull and structure; you add the drive line, motor, battery, radio and finish. Almost-ready-to-run (ARR) boats sit in between, with the building done but the electronics left to you.

Types of kits
| Type | Materials | Build time | Best for |
|---|---|---|---|
| Racing hull kits | Laser-cut plywood or fibreglass | Weekends to weeks | Speed and racing |
| Scale model boat kits | Wood, ABS, fibreglass, fittings | Weeks to months | Realism and slow running |
| Sailboat kits | Fibreglass or wood hull, rigs | Days to weeks | Racing classes, calm sailing |
| ARR boats | Built hull, no electronics | Hours | Quick start with your own gear |
What’s included and what’s not
Kits differ a lot. A basic racing hull kit may contain only the wooden parts and plans, while premium scale kits include fittings, propellers and detailed instructions. Almost all kits leave out the motor, ESC, battery, servo, receiver and transmitter, and many leave out the drive line (stuffing tube, flex shaft or prop shaft, strut and prop). Check the contents list carefully and budget for these before choosing a kit. Laser-cut plywood racing kits are described in ZippKits RC.
How to choose a first kit
- Pick your water: calm pond for scale and sail, larger lakes for fast boats.
- Pick your style: speed, realism or sailing.
- Size: 60–90 cm is easy to handle and transport and stable on small waves.
- Complexity: choose a kit described as beginner-friendly, with clear photos.
- Community: popular kits have build threads online and club experience.
Building tips
- Read the whole manual before cutting or gluing.
- Dry-fit every part; adjust before gluing.
- Use waterproof glue or epoxy below the waterline.
- Seal all wood with thin epoxy inside and out.
- Plan access hatches so you can reach the electronics.
- Test float the hull before installing everything, and check for leaks.
Hull techniques are explained in how to build an RC boat hull.
Power and running gear
Follow the kit’s recommendations. Scale boats need gentle brushed or brushless motors with a reduction, a shaft and a scale propeller, and often run for a long time on one battery. Racing hulls need powerful brushless motors with water cooling, flex shafts and specific propellers. Sailboats need a sail winch and a rudder servo. Getting this matched correctly matters more than the kit itself.
Why build a kit
Building teaches you how your boat works, so you can fix and tune it. Kits are often the only way to get a particular scale model or racing hull, and a well-built kit can last decades. The time is part of the reward: many modellers enjoy the workshop hours as much as the time on the water.
Shopping checklist
- Kit, plus drive line if not included.
- Motor, ESC and battery (or sail winch for sailboats).
- Rudder servo and radio.
- Epoxy, sandpaper, clamps and paint.
- A stand to hold the hull during building.
Common first-build mistakes
The most common mistakes are rushing the sealing so water gets into the wood, misaligning the shaft so it vibrates and wears out, and putting too much weight at the back so the boat sits tail-down. Take time with each step, check alignment by turning the shaft by hand before gluing the stuffing tube, and float-test the balance with the battery in place before painting.
FAQ
Are RC boat kits hard to build?
Beginner kits are manageable with patience; scale kits take longer.
What does ARR mean?
Almost ready to run: built boat without electronics.
What’s the best first kit?
A simple 60–90 cm hull with clear instructions.
Do kits include motors?
Usually not; check the contents list.
