Sharing the same 50.6mm diameter as the 4320 but with a shorter 59.2mm stator height, the ECOII 4315 offers a lighter 245g profile while maintaining the same 12N14P framework, 6mm steel shaft, and 30×30mm 4×M4 mounting pattern. Four KV options from 360KV to 520KV let you match the motor to your airframe and battery setup.\u003c\/p\u003e\n\u003ch3\u003eKey Features\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eStator configuration: 12N14P\u003c\/li\u003e\n\u003cli\u003eAvailable KV ratings: 360KV \/ 380KV \/ 450KV \/ 520KV\u003c\/li\u003e\n\u003cli\u003eOptimized for 13\"–15\" propellers on 6S–8S builds\u003c\/li\u003e\n\u003cli\u003e6mm steel bearing shaft with CW thread\u003c\/li\u003e\n\u003cli\u003eM6 prop adapter shaft thread\u003c\/li\u003e\n\u003cli\u003e30×30mm — 4×M4 mounting pattern\u003c\/li\u003e\n\u003cli\u003e400mm 16AWG silicone wire leads\u003c\/li\u003e\n\u003cli\u003ePrecision bearings and anodized finish\u003c\/li\u003e\n\u003cli\u003eMulti-strand winding for smooth, efficient power delivery\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eKV \/ Cell \/ Propeller Guide\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003e360KV\u003c\/strong\u003e — 6–8S — 13\"–15\" props (GF1308, HQ1310, HQ1507)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e380KV\u003c\/strong\u003e — 6–8S — 13\"–15\" props (HQ1310, GF1309, HQ1507)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e450KV\u003c\/strong\u003e — 6–8S — 13\" props (HQ1308, HQ1309)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e520KV\u003c\/strong\u003e — 6S — 13\" props (HQ1308, HQ1309, HQ1310)\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eSpecifications\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eMotor Model: ECOII 4315\u003c\/li\u003e\n\u003cli\u003eFramework: 12N14P\u003c\/li\u003e\n\u003cli\u003eDimensions: Ø50.6 × 63.7mm\u003c\/li\u003e\n\u003cli\u003eWeight (with wire): 245g\u003c\/li\u003e\n\u003cli\u003eBearing Shaft: 6mm\u003c\/li\u003e\n\u003cli\u003eProp Adapter Shaft Thread: M6\u003c\/li\u003e\n\u003cli\u003eShaft Thread: CW\u003c\/li\u003e\n\u003cli\u003eLead: 16AWG 400mm\u003c\/li\u003e\n\u003cli\u003eMounting: 30×30mm — 4×M4\u003c\/li\u003e\n\u003cli\u003eKV Options: 360KV \/ 380KV \/ 450KV \/ 520KV\u003c\/li\u003e\n\u003cli\u003ePeak Current (360KV @ 6S): 63.5A | Max Power: 2992W\u003c\/li\u003e\n\u003cli\u003ePeak Current (380KV @ 6S): 72.9A | Max Power: 2352W\u003c\/li\u003e\n\u003cli\u003ePeak Current (450KV @ 6S): 75.4A | Max Power: 2428W\u003c\/li\u003e\n\u003cli\u003ePeak Current (520KV @ 6S): 74.6A | Max Power: 1793W\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003ePackage Includes\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e4× M4×12 screws\u003c\/li\u003e\n\u003cli\u003e1× Steel M6 nylock nut\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0371\/2814\/2907\/files\/ECOII-4315_Motor_basic_information_V1.0.png?v=1787084470\" alt=\"\"\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0371\/2814\/2907\/files\/ECOII-4315_Motor_specifications_V1.0.png?v=1787084480\" alt=\"\"\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0371\/2814\/2907\/files\/ECOII-4315-360KV-Load_test_parameters.png?v=1787084510\" alt=\"\"\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0371\/2814\/2907\/files\/ECOII-4315-380KV-Load_test_parameters.png?v=1787084520\" alt=\"\"\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0371\/2814\/2907\/files\/ECOII-4315-450KV-Load_test_parameters.png?v=1787084531\" alt=\"\"\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0371\/2814\/2907\/files\/ECOII-4315-520KV-Load_test_parameters.png?v=1787084541\" alt=\"\"\u003e\u003c\/p\u003e","brand":"Emax USA","offers":[{"title":"360KV","offer_id":48192614596844,"sku":null,"price":38.99,"currency_code":"USD","in_stock":false},{"title":"380KV","offer_id":48192614629612,"sku":null,"price":38.99,"currency_code":"USD","in_stock":false},{"title":"450KV","offer_id":48192614662380,"sku":null,"price":38.99,"currency_code":"USD","in_stock":false},{"title":"520KV","offer_id":48192614695148,"sku":null,"price":38.99,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0371\/2814\/2907\/files\/4315-360KV_5.jpg?v=1787084370","url":"https:\/\/shop.emax-usa.com\/products\/emax-ecoii-4315-brushless-motor","provider":"Emax USA","version":"1.0","type":"link"}
