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. A Hobbywing QuicRun 1080 G2 standalone ESC ($35) plus an INJORA 050 66T brushed motor ($12) is a sub-$50 upgrade that completely changes how the truck feels. Smoother crawl, finer throttle, no more on-or-off launches. The 1080 G2 is the same ESC that ships on $1,000 1/10 crawlers. Massive overkill for an SCX24, which means it'll outlast the truck.
Two caveats. The 1080 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; the 1080 supports 3S but the stock plastic axle gears do not.
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're going brushless and want the reference setup
Furitek Stinger. Around $160. Pre-paired Lizard Pro ESC and Micro Komodo 1212 3450 KV motor. Bluetooth-tunable. This is what most SCX24 brushless builders run. Sensorless but the FOC firmware is smooth enough that you don't miss sensored at trail speeds.
Caveats: 3450 KV is fast on stock gearing. If you do mostly tight slow crawling you'll want to underdrive the transmission or pick a lower-KV motor.
If you're building a comp rig
Furitek Lizard Pro + Mini Komodo V2 in the 1400 to 2000 KV range. The Lizard Pro has more current headroom than the V2 for sustained low-speed crawling. The lower KV gives you walking-pace control. This is what I run on my comp builds; the FOC smoothness beats the marginal benefit of true sensored at the speeds I actually crawl.
Premium alternative: LGRP Ultimate SCX24 Performance Bundle ($250 to $350). Pre-packaged motor, ESC, and transmission. Comp-grade machining throughout. If you want a one-shot purchase and don't want to think about gearing math, this is the package.
Honorable mentions
- Castle Sidewinder Nano Micro ($90, ESC only). Premium small ESC. Pair with any micro brushless up to 4500 KV.
- Holmes Hobbies TorqueMaster Sport Micro 050 in 55T or 66T ($25 to $35). Premium brushed if you want to stay brushed but want better than INJORA.
- Mofo RC TorqueBeastX 050 ($25 to $35). Community favorite brushed motor, particularly the 20K RPM version for slow crawling.
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 a Hobbywing 1080 G2 with a 66T brushed motor (for cold mornings where I don't want to think about cogging) or a Stinger (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.
