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.
