3115 900KV 6S FPV Motor — Torque Without the Therapy

Looking for a 900KV FPV motor that plays nicely with 6S LiPo, laughs at heat, and doesn’t feel like a mystery meat special? This one’s built with Al 7075, N52H arc magnets, and proper Japanese bearings. Yes, we’re selling you a motor. No, we’re not pretending physics took the day off.

Why You Want It

This motor exists for pilots who want controlled aggression—smooth throttle, real torque, and fewer post-flight existential questions. The 12N14P layout and thin 0.2mm silicon steel stator keep efficiency high and temps sensible. Will it make you fly like a DRL finalist? No. Will it stop your quad feeling like a caffeinated shopping trolley? Absolutely.

Specifications

• KV: 900KV (torque-first, ego second)
• Voltage: 6S LiPo (because 4S had its time)
• Stator: 0.2mm Nippon silicon steel (thin laminations, thick reliability)
• Configuration: 12N14P (the crowd favourite for smooth power)
• Base Casing: Al 7075 (aircraft-grade, crash-tested by customers)
• Rotor: N52H arc magnets (high-temp magnets, low-drama flights)
• Shaft: SUS420 with M5 thread (strong enough for your prop choices)
• Bolt Pattern: M3, 19×19mm (because standards matter)
• Bearings: Japanese NMB 12×6×4 (spinny parts done properly)
• Wire: 16AWG, 30cm (long enough to regret not trimming)
• Weight: 125.2g (yes, torque has mass—welcome to reality)
