A static set has no electronics and is built mainly to display. A motorized set adds motors and a battery box so parts of the model move under power. An RC (remote-control) set is a motorized set you control wirelessly with a remote or app, so you can drive or operate it. Every RC set is motorized, but not every motorized set is RC.
What is a static building set?
A static set has no motors, batteries or wiring. You build it, and it's ready to display. That doesn't mean nothing moves, though. Many static sets have mechanical functions you work by hand, like steering that turns with the wheels, pistons that move when the car rolls, opening doors or a working gearbox.
Static sets are the simplest place to start. There's no wiring to route and no batteries to buy, so they suit first-time builders, display collectors and anyone who mainly wants a great-looking model on the shelf. If you're new to building sets in general, our beginner's guide to building block sets covers the basics.
What is a motorized building set?
A motorized set includes one or more motors and a battery box, so parts of the model move under their own power. Depending on the set, that could be pistons pumping in an engine, a crane boom lifting, a roller coaster running or a train moving along its track.
Some motorized sets are simply switched on and run, while others can be controlled more precisely. Mould King's motorized engines, for example, bring working pistons and moving parts to life, and its motorized cranes and excavators can lift, dig and turn. Browse Mould King building sets to see the range.
What is an RC building set?
An RC set is a motorized set with a wireless receiver, controlled with a handheld remote or a phone app. That lets you drive the model, steer it, or operate functions like a crane's lift and swing from a distance.
RC sets are ideal if you want to play with what you've built, not just display it. Remote-controlled cars, trucks and construction vehicles are the most common. CaDA, for example, makes RC cars and construction vehicles, including RC supercars and a telehandler. See the range of CaDA building sets.
What's the difference between static, motorized and RC sets?
| Static | Motorized | RC | |
|---|---|---|---|
| Electronics | None | Motors and battery box | Motors, battery box, receiver, and remote or app |
| How it moves | By hand, if at all | Under motor power | Under motor power, controlled wirelessly |
| Build complexity | Simplest | Extra steps for motors and wiring | Extra steps for motors, wiring and pairing the controller |
| Batteries needed | No | Yes | Yes, for the model and often the remote |
| Best for | Display, first builds, gifting | Working mechanisms and moving displays | Driving and playing with the finished model |
Can the same set come in static and motorized versions?
Yes. Some models are sold in two versions: a static version for display and a motorized version with the electronics included. The build and look are usually similar, but the motorized version adds motors, a battery box and the parts needed to fit them.
This is common with large supercar sets. Many GULY building sets, for example, are available in both static and motorized versions, and so are several EiKee building sets, including its Le Mans racers. It's worth checking which version you're buying before you order.
Which type of set should you choose?
| If you… | Choose |
|---|---|
| Want a display piece for a shelf or desk | Static |
| Are building your first set | Static |
| Love seeing mechanisms like engines and cranes in action | Motorized |
| Want to drive or operate the model from a distance | RC |
| Can't decide | A model sold in both static and motorized versions, so you can pick the one that suits you |
For a first build, a static set is usually the easiest start. Our picks of the best building sets for beginners can help you choose. If moving parts are what excite you, see our guide to the best motorized building sets.
What should you know before buying a motorized or RC set?
- Check the batteries. Some sets include a rechargeable battery, while others need AA batteries that may not be included.
- Check the controls. If a set uses an app, make sure your phone is supported and has Bluetooth.
- Allow extra build time. Routing cables and fitting motors adds steps, so take your time and test each motor as you go.
- Keep electronics within one system. Motors, battery boxes and remotes are usually designed to work together within one brand, so mixing brands can cause problems. Our guide to whether motors and power systems are compatible across brands explains why.
- Bricks still mix. Standard bricks and Technic-style parts usually connect across brands, as our brick compatibility guide explains, even when the electronics don't.
FAQs
Is a motorized set the same as an RC set?
Not quite. A motorized set has motors that move parts of the model. An RC set is a motorized set you also control wirelessly with a remote or app. All RC sets are motorized, but not all motorized sets are RC.
Do static sets have any moving parts?
Often, yes. Many static sets include mechanical functions you work by hand, like steering, opening doors or pistons that move when the wheels turn.
Are motorized sets harder to build?
They have extra steps, like fitting motors, routing cables and connecting the battery box. They're not necessarily harder, but they take more care, so they suit builders who enjoy a technical challenge.
Can I add motors to a static set later?
Sometimes. The easiest options are a motorized version of the same set or the brand's own upgrade kit, if one exists. Otherwise, check that any motor kit's connectors and mounting points will fit the model.
Do RC sets come with a remote?
Most RC sets include a remote, and some can also be controlled with a phone app. Check the product details to see which control options a set includes.
Which is better for display, static or motorized?
Both display well. A static set is simpler and has no battery box to hide, while a motorized set lets you show off moving mechanisms whenever you like.
