{"product_id":"xing2-2405-1800kv-4s-6s-fpv-motor-pre-tested-ultralight-5","title":"XING2 2405 1800KV 4S\/6S FPV Motor | Pre-Tested Ultralight 5\"","description":"\u003ch3\u003eUltralight 5\" Performance — No Compromise.\u003c\/h3\u003e\n\n\u003cp\u003eThe XING2 2405 fills a specific gap that experienced builders will recognize: you want 5-inch performance, but you're building light. This motor shaves nearly 5 grams per corner compared to a standard 2306, bringing your all-up weight down without sacrificing the torque you need for freestyle tricks. The 2405 stator is wider than a 2207 but shorter than a 2306 — a geometry that keeps weight low while maintaining strong magnetic flux for responsive throttle control.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003e1800KV is the unicorn number.\u003c\/strong\u003e It runs clean on both 4S and 6S batteries. On 4S with 5-inch triblade props you get a lively, responsive feel that's perfect for lighter builds and indoor-style freestyle in tighter spaces. On 6S the same motor opens up — punch-outs feel immediate, and the top-end speed surprises pilots who expect a lightweight motor to gas out early. You get two builds worth of versatility from one set of motors.\u003c\/p\u003e\n\n\u003cp\u003eThe Unibell construction means no set screws to back out, no bell separation mid-flight. The N52H magnets hold their flux density at temperature, so your third pack on a hot day feels as sharp as the first. The 2405's smaller diameter also means less gyroscopic precession — the quad feels more agile in flips and rolls compared to heavier motors. Japanese EZO bearings ensure smooth spin from day one and hold up through hundreds of packs before needing replacement.\u003c\/p\u003e\n\n\u003ch3\u003eSpecifications\u003c\/h3\u003e\n\u003ctable style=\"width:100%; border-collapse:collapse; margin-bottom:20px;\"\u003e\n  \u003ctr style=\"background:#f5f5f5;\"\u003e\n\u003ctd style=\"padding:8px 12px; border:1px solid #ddd; font-weight:bold;\"\u003eStator Size\u003c\/td\u003e\n\u003ctd style=\"padding:8px 12px; border:1px solid #ddd;\"\u003e2405\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003ctr\u003e\n\u003ctd style=\"padding:8px 12px; border:1px solid #ddd; font-weight:bold;\"\u003eKV Rating\u003c\/td\u003e\n\u003ctd style=\"padding:8px 12px; border:1px solid #ddd;\"\u003e1800KV\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003ctr style=\"background:#f5f5f5;\"\u003e\n\u003ctd style=\"padding:8px 12px; border:1px solid #ddd; font-weight:bold;\"\u003eBattery\u003c\/td\u003e\n\u003ctd style=\"padding:8px 12px; border:1px solid #ddd;\"\u003e4S or 6S — dual voltage capable\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003ctr\u003e\n\u003ctd style=\"padding:8px 12px; border:1px solid #ddd; font-weight:bold;\"\u003eProp Range\u003c\/td\u003e\n\u003ctd style=\"padding:8px 12px; border:1px solid #ddd;\"\u003e5-inch (triblade recommended)\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003ctr style=\"background:#f5f5f5;\"\u003e\n\u003ctd style=\"padding:8px 12px; border:1px solid #ddd; font-weight:bold;\"\u003eShaft\u003c\/td\u003e\n\u003ctd style=\"padding:8px 12px; border:1px solid #ddd;\"\u003eM5\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003ctr\u003e\n\u003ctd style=\"padding:8px 12px; border:1px solid #ddd; font-weight:bold;\"\u003eMounting\u003c\/td\u003e\n\u003ctd style=\"padding:8px 12px; border:1px solid #ddd;\"\u003e16x16mm\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003ctr style=\"background:#f5f5f5;\"\u003e\n\u003ctd style=\"padding:8px 12px; border:1px solid #ddd; font-weight:bold;\"\u003eWeight Savings\u003c\/td\u003e\n\u003ctd style=\"padding:8px 12px; border:1px solid #ddd;\"\u003e~5g lighter per motor vs 2306 = ~20g off AUW\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\n\n\u003ch3\u003eBuild Suggestions\u003c\/h3\u003e\n\u003cp\u003eThis motor really shines on sub-250g 5-inch builds or lightweight freestyle quads.
