Designed for an 11.1 V battery voltage, it produces up to 1250 g of thrust, enabling the stable flight of medium-weight aircraft.\u003c\/p\u003e \u003cp\u003eThe motor requires an electronic speed controller (ESC), which regulates the rotational speed using a control signal from the flight controller. Counterclockwise rotation is required to compensate for reactive torque in symmetrical four-propeller configurations; without the correct motor arrangement, uncontrollable torque will occur. A current draw of up to 15 A requires an ESC with the appropriate current rating.\u003c\/p\u003e \u003cp\u003eThe motor is used in compact multicopters that perform stabilized aerial photography or transport payloads weighing up to a few hundred grams. With a flight weight in the range of 900 to 1200 g, an aircraft equipped with four such motors can be operated.\u003c\/p\u003e \u003cp\u003eA flight controller that outputs PWM or digital control signals is required for operation. The appropriate ESC must be rated for at least 15 A. A stable 3-cell battery with sufficient discharge current capability is also required; in addition, all four motors must have very similar specifications to achieve balanced flight.\u003c\/p\u003e \u003ch3\u003eSafety Notice\u003c\/h3\u003e \u003cp\u003eThis product is not intended for operation on household electrical circuits and is intended exclusively for testing and prototype construction. High-voltage sources or improper power supplies can cause damage and fires; check all connections before initial operation. If you have questions about electrical safety, consult a qualified electrician.\u003c\/p\u003e","brand":"Funduino","offers":[{"title":"Default Title","offer_id":66044423078237,"sku":"F23108433","price":22.78,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1074\/5649\/5965\/files\/walkera-runner-250-brushless-motor-ccwwk-ws28-014-2100kv-runner-250-z14-funduino-2821564.jpg?v=1791488056","url":"https:\/\/funduino.com\/en\/products\/walkera-runner-250-brushless-motor-ccwwk-ws28-014-2100kv-runner-250-z14","provider":"Funduino","version":"1.0","type":"link"}
