SEQURE ANT ESC V2 & 1520 Motor Review — Worth it for 1/24–1/16 RC Crawlers?
Introduction
Small-scale RC crawlers (1/24, 1/18, 1/16) pose a set of consistent challenges: limited internal space, weight sensitivity that affects balance and center of gravity, and a need for smooth, low-speed torque for technical climbing rather than raw top speed. Many stock brushed or generic brushless setups either overheat, add too much mass, or lack the programmable finesse hobbyists want. The SEQURE ANT ESC V2 paired with the 1520 outer-rotor motor aims to solve those pain points by delivering a compact, waterproof, programmable power kit with a built-in BEC and a motor engineered for efficiency and torque in tight packages.
Specifications & Materials (Material & Quality)
The hardware and build quality are among the first things you notice with this kit. SEQURE clearly designed the ANT ESC V2 and 1520 motor to be both compact and durable.
- ESC (ANT ESC V2)
- Size: 28 × 17.3 × 11 mm; Weight: 16.6 g (incl. wires)
- Input voltage: 2–4S LiPo (DC 7V–17V)
- Continuous current: 60A (good heat dissipation); peak 120A
- Firmware: ESCape32 (supports DShot, PWM, Oneshot, Multishot)
- Programmable BEC: selectable 6V / 7.4V / 8.4V / 12V at 5A continuous
- Sealed glue-filled PCB and aluminum housing for water/dust resistance
- Electronic touch switch (no mechanical wear)
- Includes various battery adapter cables, 3M tape, cable ties
- Motor (1520 Outer Rotor)
- Size: 15.8 × 20.7 mm; Weight: 16.8 g (incl. wires)
- Working voltage: 2–3S LiPo; KV: 3500KV
- 9N12P design, hardened shaft, high-temp magnets, quality bearings
- Outer rotor construction for better low-speed torque and thermal mass
- Comes with 24T/16T/11T pinion options
Build quality notes
- The aluminum ESC shell and sealed PCB give a reassuring IP-ish protection for crawling use in damp, dusty conditions (not officially IP-rated, but robust in practice).
- Motor bearings and hardened shaft are solid for scale use; wire gauge and silicone insulation feel appropriate for the current rating.
- Included wiring and adapters make installation plug-and-play for many models without chopping connectors.
Real-world Experience — Pros & Cons
I tested the ANT ESC V2 + 1520 motor on two chassis: a lightweight 1/24 scaler and a 1/18 basement crawler. Runs included technical rock crawling, low-speed mossy logs, and a few short hill sprints. Here’s how it performed in real conditions.
Pros
- Size-to-power ratio: The package is tiny and light. It installs cleanly in narrow frames without upsetting balance or requiring major chassis mods.
- Smooth low-speed control: Outer rotor motor plus ESCape32 tuning gives very linear, predictable throttle for technical crawls—easy feathering at low throttle.
- Programmability: Mobile/computer parameter tuning (timing, brake, throttle profile, LVC, temp protection) is a big win. Fine-tuning made climbs more controllable than stock setups.
- Water/dust resilience: The glued PCB and aluminum case kept dust out and survived splashy runs without hiccups.
- Built-in programmable BEC: 5A output at selectable voltages is enough to drive beefier micro servos for tight steering without an additional UBEC on many builds.
- Electronic switch: Convenient and long-lived compared to mechanical buzzers or inline switches.
Cons
- Limited continuous BEC headroom: 5A is fine for most micro servos, but if you run a power-hungry metal-gear micro or additional accessories (lights, winch), you may max it out.
- Thermals under heavy load: While the ESC has good heat dissipation for its size, extended heavy climbs on 4S or sustained high-current conditions push temps up; consider ventilation or a temperature cutoff setting.
- No official IP rating: The glue-sealed design works well but lacks formal IP certification—submerge at your own risk.
- WiFi link optional: The WiFi-Link in the bundle adds convenience for on-the-fly tuning; the ESC alone requires a separate adapter or cable for parameters.
Bottom line: For small-scale crawlers that prioritize smooth low-speed performance and compact packaging, this SEQURE combo punches above its weight. It’s a thoughtful, hobbyist-friendly solution with a few realistic caveats around heavy-duty current and deep-water use.

Quick Comparison
How does SEQURE’s kit stack up against other popular choices in this segment?
| Feature | SEQURE ANT ESC V2 + 1520 | Hobbywing compact crawler ESCs (general) |
|---|---|---|
| Size & Weight | Very small/light — fits tight frames | Also compact, but fewer outer-rotor motor pairings available |
| Programmability | ESCape32, mobile/computer tuning; many advanced options | Good — usually via program cards or apps, but varies by model |
| Water resistance | Glue-sealed PCB + aluminum case — robust, not IP certified | Many Hobbywing ESCs are waterproof-rated (some with IP rating) depending on model |
| Price | ESC $33.99 / Motor $18.99 / Bundle $59 (USD) | Varies — generally comparable or slightly higher for branded waterproof models |
Note: Hobbywing and other established brands may offer official waterproof ratings and broader dealer support. SEQURE’s advantage is the compact, integrated approach with ESCape32 flexibility at a competitive price point.
Who Is This Best For?
- RC hobbyists running 1/24, 1/18, or 1/16 scale crawlers who need a compact, tunable powertrain.
- Drivers who prioritize low-speed control and technical crawling performance over raw speed.
- Modders who want a programmable ESC (ESCape32) and the convenience of an integrated BEC and electronic switch.
- Builders who want a near plug-and-play solution with included adapters and pinions.
Pricing & Purchase Options
- ANT ESC V2 — $33.99 (USD)
- 1520 Motor — $18.99 (USD)
- ANT ESC V2 & 1520 Motor & WiFi-Link bundle — $59.00 (USD)
Final Verdict
The SEQURE ANT ESC V2 paired with the 1520 outer-rotor motor is a compelling, well-engineered option for small-scale crawlers. It combines compact packaging, smooth low-speed torque, and rich programmability at a competitive price. If you need an all-around upgrade that won’t upset your chassis balance and offers fine-grain tuning, this kit is worth serious consideration.
Note: If you’re planning to run high-draw servos or frequent heavy climbs on 4S, factor in additional cooling or an auxiliary BEC. Also consider the optional WiFi-Link for quicker on-the-trail tuning.

Quick Setup Tips
- Start with conservative timing and throttle curve settings; tune up gradually if you need more responsiveness.
- Use the included pinions to match gearing for torque-first crawling rather than speed.
- Monitor ESC temperature during your first long sessions and enable over-temp protection in settings if you see rising temps.
