1/18 vs 1/20 Scale RC Cars: Which Small-Scale Truck Is Right for You?

When you're shopping for a small-scale RC truck, the difference between 1/18 and 1/20 scale can feel subtle on paper but significant in practice. Both are compact, affordable, and perfect for indoor or backyard bashing, but they cater to slightly different priorities. In this guide, we break down the key differences to help you choose the right mini RC truck for your needs.

We'll compare size, parts availability, performance, and upgrade potential, drawing on popular models like the FTX Tracer 1/16 4WD Truggy and the RCG Racing MT-One 1/16 Monster Truck. By the end, you'll know which scale fits your driving style and budget.

Size and Portability: How Big Is the Difference?

The most obvious difference between 1/18 and 1/20 scale RC trucks is physical size. A 1/18 scale truck is roughly 10-12 inches long, while a 1/20 scale model is slightly smaller, typically around 9-10 inches. This may not sound like much, but it affects handling and where you can drive.

Smaller 1/20 scale trucks are easier to stash in a backpack and can navigate tight indoor spaces like living rooms or small yards. 1/18 scale trucks, being a bit larger, feel more stable on grass and gravel, and they're easier to work on because parts aren't as tiny. If you plan to drive mostly indoors or on smooth surfaces, the smaller size is an advantage; for outdoor use, the extra inch or two of 1/18 scale helps.

• Measure your intended driving area: if it's under 10 square feet, a 1/20 scale truck is more maneuverable; if you have a driveway, 1/18 scale handles bumps better.

Performance and Handling: Speed vs Agility

Performance-wise, both scales are available in brushed and brushless configurations, but 1/18 scale trucks often have more powerful motor options and better suspension geometry, making them faster and more capable on uneven terrain. The FTX Tracer 1/16 4WD Truggy, for example, is a 1/16 scale but offers a similar footprint to 1/18, with excellent handling and durability.

1/20 scale trucks are typically less powerful and more toy-like, but they're also lighter and more agile, which can be fun for tight turns and indoor drifting. If you're a beginner, a 1/20 scale might be less intimidating, but if you want room to grow and upgrade, 1/18 scale offers more aftermarket support.

• For a first RC, a 1/20 scale truck is easier to control at lower speeds; for a more engaging experience, choose 1/18 scale with a brushless motor option.

Durability and Parts Availability

Durability is critical for any RC truck, especially when driven by kids or beginners. 1/18 scale trucks tend to have more robust construction and a wider range of spare parts, thanks to their popularity in the hobby. Brands like RCG Racing offer upgrade parts such as the RCG Racing Tracer / MT-One Shock Towers and the RCG Racing Tracer / MT-One Front/Rear Lower Suspension Hinge Pins, which are designed for 1/16 and 1/18 scale models.

1/20 scale trucks, on the other hand, are often sold as ready-to-run toys with limited spare parts. If you break a suspension arm or hinge pin, you might have to buy a whole new truck. For long-term ownership and repairability, 1/18 scale is the safer bet.

• Check if the model you like has replacement parts listed on the store. If not, consider a 1/18 scale truck like the RCG Racing MT-One 1/16 Monster Truck, which shares many parts with the Tracer.

Upgrade Potential: Which Scale Offers More?

Upgradeability is a major factor for hobbyists. 1/18 scale trucks have a thriving aftermarket, with options for brushless motors, metal gears, and upgraded suspension components. For instance, you can enhance your 1/16 or 1/18 scale truck with parts like the RCG Racing Tracer / MT-One Front Upper Suspension Hinge Bolts (4pcs) or the RCG Racing Wind Speed/ Storm Rider Brushless Motor Guard.

1/20 scale trucks are less upgrade-friendly, with fewer compatible parts and less room for electronics upgrades. If you enjoy tinkering and personalizing your RC, 1/18 scale is the clear winner. If you just want a simple, fun toy that requires no maintenance, 1/20 scale might suffice.

• Look for models with standard 1/10 scale-compatible electronics (like a 2S LiPo battery) to ensure easier upgrades. The RCG Racing 7.4v (2S) 600mAh 1/16 Drift Car Replacement Li-Ion Battery is a good example of a compatible upgrade.

Price and Value: What's the Real Cost?

Generally, 1/20 scale trucks are cheaper upfront, making them attractive for parents buying a first RC for a child. However, they often lack the durability and repairability of 1/18 scale models, which can lead to higher long-term costs if you need to replace the whole vehicle.

1/18 scale trucks are slightly more expensive but offer better performance, parts availability, and resale value. For most hobbyists, the extra investment is worth it. Consider your budget and how much you're willing to spend on repairs or upgrades in the future.

• If you're on a tight budget, a 1/20 scale truck like the Maverick Microbe 1/24 Buggy (though 1/24) can be a fun starter, but be prepared to replace it sooner.

Choosing between 1/18 and 1/20 scale RC trucks ultimately comes down to your priorities. If you want a durable, upgradeable, and more capable mini RC truck that can handle a variety of terrains, go with 1/18 scale. If you prefer a compact, budget-friendly option for casual indoor play, 1/20 scale is fine. Either way, you'll enjoy the thrill of small-scale RC bashing.
