⚡ GEPRC SPEEDX2 1404 3850KV — Compact Power for Mini FPV
The GEPRC SPEEDX2 1404 3850KV motor is a prime example of how far micro FPV technology has evolved. In the past, pilots who wanted to build 3–4″ drones often had to accept compromises: either go with heavy motors that gave good thrust but ruined agility, or use lighter options that lacked durability and torque. The SPEEDX2 1404 changes this equation by combining light weight (~10.5 g with leads), strong magnetic design, and efficient engineering into a package that feels perfectly balanced for modern mini builds.
At 3850KV, this motor is tuned for 4S setups—offering a middle ground between high-revving punch and manageable efficiency. That makes it versatile: whether you’re building a freestyle 3″ quad for tight gaps, a cinewhoop for smooth footage, or even a light racer where every gram matters, this motor provides both responsiveness and longevity.
Its N52H magnets, NSK/NMB bearings, and 9N12P stator structure aren’t just spec sheet items—they directly translate into torque stability, smooth flight characteristics, and better throttle resolution. For pilots, this means faster control response in freestyle, crisper handling in racing, and steadier hover for cinematic work. In short, the SPEEDX2 1404 3850KV isn’t just about raw numbers—it’s about refined performance tailored to the micro class.
🧠 Key Features & Build Intelligence
This motor is built with engineering choices that prioritize both durability and agility. The N52H magnets deliver high magnetic strength while resisting demagnetization at higher temps, and the NSK/NMB bearings ensure smoother rotation for extended life. Combined with a single-strand copper winding layout, the SPEEDX2 maintains efficient heat dissipation even under heavy throttle punches.
The aesthetic design — a red-and-black anodized finish — not only looks sharp but also signals its premium machining quality.
📊 Specs That Matter (Explained)
The motor’s 18.2 × 13.8 mm body houses a 3850KV stator that hits a sweet spot for 4S LiPo setups. With 3–4″ props, you can expect ~10 A draw at peak throttle and up to 160 W of output power, making it more than capable for aggressive freestyle bursts or smooth cinewhoop cruising.
The 1.5 mm shaft (4 mm protrusion) ensures solid prop mounting, while the 9×9 mm mounting pattern with M2 screws guarantees compatibility with most micro frames. The 160 mm (26 AWG) motor wires are long enough for versatile routing, reducing build frustration. For ESCs, a 12 A+ rated 4-in-1 is recommended to handle bursts cleanly.
🏆 Why It Stands Out
What sets the SPEEDX2 1404 3850KV apart is how balanced it feels. Many micro motors chase only one direction—either extreme KV for raw speed or low KV for efficiency. This motor sits in the perfect middle zone: fast enough for racing and freestyle tricks, yet efficient enough to keep flight times practical. Its low inertia makes stick movements feel immediate, while its magnetic strength ensures you never lose torque mid-maneuver.

⭐ What Pilots Say
★★★★★ Leo – 3″ Freestyle Pilot
“On 4S, the throttle feels razor-sharp. Small quads feel like they gained big-quad control.”
★★★★☆ Nina – Lightweight Racer
“Smooth bearings and good consistency. Soldering the leads was simple, though pre-soldered would’ve been nice.”
★★★★★ Max – Cinewhoop Enthusiast
“Runs cool during 5–6 min flights with ducts. Perfect balance of power and stability.”
★★★★★ Aria – FPV Competitor
“3850KV is the sweet spot for me — not too thirsty, but powerful enough to win heats.”
★★★★☆ Sam – Micro-Quad Hobbyist
“Very light at ~10 g. Feels strong for the size. Minor vibes on idle, but nothing tuning can’t fix.”
★★★★★ Zoe – Drone Builder
“The machining and red/black finish are top-notch. My builds look cleaner and fly tighter.”
★★★★☆ Omar – Throttle Tester
“Torque at mid-stick is great. Loud on high KV, but that’s expected—it’s aggressive!”
★★★★★ Mia – Speed Chaser
“With 3″ props, power loops feel buttery smooth. Exactly what I wanted in a micro motor.”
★★★★★ Ethan – Tech Reviewer
“Heat management is excellent. Efficiency at hover is better than I expected for 3850KV.”
★★★★☆ Ava – New Pilot
“Responsive and forgiving. Great for beginners who want performance without fragility.”

Discover GEPRC
GEPRC focuses on the FPV ecosystem, from ready-to-fly quadcopters and cinewhoops to airframes, electronics, motors and navigation accessories. Its product families serve pilots looking for cinematic flying, freestyle performance, long-range exploration or carefully selected parts for custom aircraft.
GEPRC equipment rewards attention to the complete build rather than any single component. A GPS module must match the flight controller's available connections, a battery must suit the voltage and dimensions of an airframe, and a video or radio configuration must align with the pilot's existing control and viewing system.
Explore the brand by starting with your flying style and aircraft size. Check receiver protocols, video transmission, mounting, operating voltage and firmware before choosing related parts. That compatibility-first approach makes it easier to build a dependable and purposeful FPV setup.
