The Brushless Question

The most common question I see from new SCX24 owners is some version of: “When should I upgrade to brushless?”

I asked the same question about six weeks in. I’d read enough threads to know brushless motors were faster, more efficient, and what the serious crawlers ran. It felt like a natural next step.

After actually doing the upgrade and running both, I’ve come to think the question itself is a little bit wrong.

What You’re Actually Asking

When beginners ask about brushless, they’re usually asking one of two different things without realizing it.

The first version is “I want more power.” That’s a reasonable thing to want. The stock brushed motor in the SCX24 is not a monster. On loose terrain or anything with real incline, you can feel where its limits are.

The second version is “I want better slow-speed control.” This one is more interesting. Crawling is not about top speed. It never is. What you actually need in technical terrain is the ability to feed power in tiny increments. A small push to place a tire, a slight hold to keep momentum without overshooting. The brushed motor handles this reasonably well at first, but once you’ve driven enough, you start feeling the on/off character of the power curve.

Those two problems have different solutions, and knowing which one you actually have matters.

The Case for Waiting

I’m going to say the thing nobody on the forums says: if you haven’t broken anything yet, you’re probably not ready for brushless.

That sounds backward. But what brushless requires is that you know your truck well enough to know what you’re trying to change. If you’ve never noticed the difference between a loose line and a committed one, never run a session focused entirely on wheel placement, then brushless is going to make your rig faster and teach you nothing.

More speed into bad decisions is still bad decisions.

The stock motor is a reasonable learning environment. It’s forgiving and predictable. Running it longer than you feel like you should is not falling behind. It’s staying in the classroom until the material makes sense.

When the Question Changes

There’s a version of this that flips. You’ve been running stock for a while. You’ve learned your lines. You’re not fighting the truck anymore. And now you start noticing specific things.

The truck bogs on a long loose climb. Or you’re in a tight technical section and you want a finer grain of control than the stock ESC is giving you. Those are real signals. They’re different from “I just want more.”

Once you can name what you want the upgrade to fix, the upgrade is worth doing.

If you’re at that point and starting to dig into what actually changes when you swap motors, the SCX24 beginner mods guide is useful because it covers the whole modification sequence, not just the motor step. Knowing what else is upstream or downstream of the brushless swap saves you from doing things in the wrong order.

What Actually Changes

I ran the stock brushed setup for about three months before I swapped anything. It was genuinely capable. I was not suffering.

After brushless, the slow-speed control improved noticeably. The difference shows up most in tight technical terrain. There’s a smoother relationship between trigger input and wheel response. The old stock feeling was “nothing, nothing, nothing, go.” Brushless is more “a little, a little more, a little more.”

The power increase is real but not as significant as the forum conversations made me expect. You’re still a small crawler. The terrain doesn’t care about your motor specs.

What I did not expect: brushless made me a slightly worse driver for about two weeks while I relearned the throttle curve. Muscle memory from the brushed setup was overconfident in a few places. That’s not a reason to avoid the upgrade. It’s just something to know going in.

The Short Answer

If you’ve owned your SCX24 for less than two months and haven’t broken a steering link yet, run the stock setup longer. Not because you can’t handle brushless, but because you’ll get more out of it once you have more reps on the terrain.

When you can consistently read a line before you drive it, when you understand why you lost traction in that one spot, when the truck is starting to feel like the limitation rather than your inputs. That’s the window.

It’ll make sense when you get there.
