The motor and ESC question on an SCX24 is really four questions stacked on top of each other: brushed or brushless, sensored or sensorless, what KV, and how do you wire it through the stock 2-in-1 electronics. The brushed vs. brushless explainer covers the theory. This article is the shortlist of what I actually buy. Across 20+ builds I've landed on a small number of combos that I trust.
If you're upgrading from stock for the first time
Go brushed. An INJORA MB100 G2 standalone brushed ESC (around $25) plus a brushed motor from MofoRC or LGRP, like the MofoRC TorqueBeastX 50 (around $18) or an LGRP brushed motor (around $12), is a sub-$50 upgrade that completely changes how the truck feels. Smoother crawl, finer throttle, no more on-or-off launches.
Two caveats. A standalone ESC needs a separate receiver on post-2021 trucks (Bronco, Gladiator, late JLU) because their stock 2-in-1 board has no usable channel 2 bypass. Budget for a Flysky FS2A or similar. And stay on 2S unless you're sure your ESC and motor can handle 3S; the stock plastic axle gears won't like it either.
If you're going brushless on a budget
INJORA MBL32 + Purple Viper 1721 2200 KV. Around $60 to $70 combined. Sensored brushless, waterproof ESC, includes the receiver. Best value brushless combo on the platform. Smooth slow-speed control because it's actually sensored, not just FOC. Confirm the receiver protocol matches your transmitter before you buy.
If you want plug and play brushless
Furitek MicroSilk 2025 Brushless Power System. Around $100. Pairs the MicroPython ESC with a MiniKomodo motor, made for the SCX24. Bolt it in, bind it, drive. If you mostly do slow, tight crawling, see the KV notes below before you pick gearing.
If you want to go fully custom
This is what I like doing on my own builds: a JK RC Performance transmission, a brushless motor of my choice, and a Furitek ESC. On my comp builds that's usually a Furitek Lizard Pro with a Mini Komodo in the 1400 to 2000 KV range; the lower KV gives you walking pace control. More money and more work than a combo, but you pick every piece.
KV recommendations by use case
- Hardcore comp: 1400 to 2000 KV sensored, with overdriven gearing to recover wheel speed on flats.
- Mixed trail with some comp: 2200 to 2700 KV sensored.
- Casual trail: 2500 to 2800 KV sensored or FOC sensorless.
- Trail + light bash: 2800 to 3500 KV.
What I actually run
My current rigs split into two camps. Comp builds run Lizard Pro + Mini Komodo V2 in the 1400 to 1800 KV range. Trail and scale builds run either an INJORA MB100 G2 with a MofoRC or LGRP brushed motor (for cold mornings where I don't want to think about cogging) or a Furitek brushless system (when I want the speed). I bind everything to a Flysky GT5 with FS-BS6 or FS2A receivers, which lets me hold up to 20 builds on a single transmitter and pick the ESC I actually want without protocol headaches.
