RC Scale Explained: 1/10 vs 1/8 vs 1/5 in 2026

If you're new to RC, "scale" is one of the first terms you'll run into — 1/10, 1/8, 1/5, and more. It's simple once it clicks, and it has a big impact on size, speed, runtime, and cost. Here's what RC scale means and how to choose.

What "scale" means

Scale is the size of the model relative to a real, full-size vehicle. A 1/10 scale truck is roughly one-tenth the size of the real thing; a 1/5 scale model is one-fifth — so a larger number after the slash means a smaller model. 1/10 is smaller than 1/8, which is smaller than 1/5. That single number shapes almost everything about how the vehicle behaves.

1/10 scale: the all-rounder

1/10 is the most popular scale in the hobby. These vehicles are big enough to handle rough terrain and small enough to run in a backyard or park, and they have the widest selection of models, parts, and upgrades. For most beginners and a huge share of enthusiasts, 1/10 is the sweet spot for value and versatility. Most Redcat crawlers, short course trucks, and monster trucks are 1/10.

1/8 scale: more size and power

1/8 vehicles are noticeably bigger, heavier, and more powerful. The extra mass helps them handle bumps and jumps with more stability and presence, and they typically run bigger motors and batteries for higher speeds. They cost more than 1/10 and need more space to run, but deliver a more dramatic, planted feel — popular for bashing monster trucks like the Redcat Kaiju.

1/5 scale: big-rig territory

1/5 scale is the large-format end of the hobby — these machines are huge, often gas-powered, and built for wide-open spaces. They have serious presence and power, longer runtimes (especially gas models), and a price and maintenance commitment to match. Models like the Redcat Rampage are 1/5 gas-powered and aimed at experienced hobbyists with room to run.

Which scale should you choose?

Choose 1/10 for the best balance of size, cost, selection, and where you can run it — ideal for most beginners. Choose 1/8 if you want more size, stability, and power for bashing and have a bit more space and budget. Choose 1/5 if you want maximum presence, have wide-open areas, and are ready for a larger investment.
