Like full-size rigs, radio-controlled (RC) cars and trucks come in a varying array of shapes and sizes. Inside the rock crawling subset alone, the range extends from massive 1/6 and tiny micro crawlers. But by far the most popular are the middle three: 1/10, 1/18, and 1/24 scale.
Here's a quick rundown of the most popular (and commonly used) sizes when it comes to radio-controlled rock crawlers: Toy Food
These are the most common and popular scale for RC crawlers. In general, a 1/10 scale RC crawler is larger and typically measures around 18-24 inches (45-60 cm) in length. They often have more intricate details and can handle rough terrain quite well due to their larger size.
A 1/18 scale RC crawler is smaller in comparison to the 1/10 scale. These models usually measure around 10-12 inches (25-30 cm) in length. They are more compact and may have slightly less detail than their larger counterparts, but they can still perform admirably on moderate off-road terrains.
These are the smallest among the three. A 1/24 scale RC crawler measures approximately 5-7 inches (12-18 cm) in length. Due to their smaller size, they might not have as much intricate detailing and may struggle with very rough terrain. However, they can be a lot of fun for indoor or smaller outdoor courses.
Each scale offers its own advantages and limitations based on size, detail, performance, and suitability for different terrains. The choice often depends on personal preference, available space for running, and the desired level of detail and performance. Some of this does come down to whether the buyer is more interested in the "scale" side of things ( how well the RC replicates the real thing) or the rock crawling itself.
The 1/10 scale RC crawlers stand as the most prevalent and widely embraced scale among enthusiasts who run their rigs outdoors. One of the most noticeable features of 1/10 scale crawlers is their enhanced detailing and realism. Manufacturers can incorporate intricate designs and finer details into these models due to the larger size, resulting in a more lifelike appearance. The increased size also allows for more functional components, such as more significantly realistic suspension systems, scaled accessories, and working lights, enhancing the overall realism and user experience.
Furthermore, the larger dimensions of 1/10 scale crawlers often translate to improved performance on rough terrains. Their size grants them better ground clearance, stability, and capability to overcome obstacles, making them suitable for challenging off-road courses and rock crawling. Added weight also adds to the realism, with some weighing as much as 10 pounds.
1/10 scale is great for trail running and exploring the capabilities of the vehicle on Earth's own geology, rather than indoors on man-made obstacles. While a 1/10 can be used on some dedicated indoor courses, they're better reserved for outside as their size can limit indoor use. The 1/10 crawler seen here is the RC4WD C2X, which you can read more about in coming stories.
Comparatively smaller than the 1/10 scale, the 1/18 scale RC crawlers offer a more compact and portable option for enthusiasts. These models typically measure around 10 to 12 inches (25-30 cm) in length, making them notably smaller than their 1/10 scale counterparts.
Despite their smaller size, 1/18 scale crawlers retain several appealing attributes. While they may lack the intricate detailing of larger scales, they still exhibit a decent level of realism and functionality. Manufacturers strive to incorporate essential features while maintaining a balance between scale realism and size constraints. Due to their reduced dimensions, 1/18 scale crawlers might have fewer working parts or slightly less detailed components compared to 1/10 scale models. The aftermarket has solved that, going so far as to offer endless upgrades and replacement parts that are as detailed as what's available on 1/10 scale trucks.
These smaller crawlers have their own advantages. Their compact size makes them more suitable for indoor use, smaller outdoor terrains, or areas with limited space. Additionally, they remain capable of navigating moderate off-road tracks and obstacles, although their performance might not match that of larger scales. We've been running the 1/18 scale Traxxas TRX4M Defender for a year and love it for its middleground size, which allows it to be great indoors while still handling larger obstacles with relative ease, and a plethora of available modifications makes for fullsize fun in true scale form.
The 1/24 scale RC crawlers represent the smallest size category among these three scales. Typically measuring around 5 to 7 inches (12-18 cm) in length, these models offer a miniature yet intriguing option for RC enthusiasts. Note that the FMS FCX24 Power Wagon seen here is a bit larger than the common 1/24 crawlers.
1/24 scale crawlers generally compromise on certain aspects such as intricate detailing and functional components. Manufacturers face limitations in incorporating highly detailed features at this scale, leading to a trade-off between realism and size constraints. However, despite these limitations, 1/24 scale crawlers still manage to maintain a reasonable level of visual appeal and functionality within their compact form. Similarly, manufacturers like FMS find creative ways to incorporate details to keep things interesting, like the portal axles seen on the FCX24.
The primary advantage of these smaller crawlers lies in their suitability for indoor use, tabletop courses, or confined spaces where larger scales might struggle to maneuver. Their size allows enthusiasts to create miniature off-road courses or use small spaces like kids' playrooms as crawling courses, fostering creativity in designing challenging terrains within limited areas. While they might face limitations in handling extremely rough terrains, 1/24 crawlers provide an entertaining and accessible entry point into the world of RC crawling.
The choice between 1/10, 1/18, and 1/24 scale RC crawlers largely depends on individual preferences, intended usage, available space, and desired level of detail and performance. While larger scales like 1/10 offer enhanced realism and superior off-road capabilities, smaller scales such as 1/18 and 1/24 excel in compactness, indoor use, and maneuverability within constrained spaces. Ultimately, each scale presents its unique advantages, catering to a diverse range of enthusiasts in the world of RC crawling.
