Each motor has a JST1.25 3-pin connector, so they plug straight into boards like the Matrix 1S 3IN1 and 5IN1 II.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003e\u003cem\u003eWhich screws should I use?\u003c\/em\u003e\u003c\/strong\u003e\u003cbr\u003e\nThe pack includes 16× M1.4×4 screws. Always match screw length to your frame's recommended motor screw. For example, BETAFPV lists M1.4×3mm for the Meteor75 Pro II frame. Screws that are too long can reach the motor windings.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003e\u003cem\u003eWhat flight controller works best?\u003c\/em\u003e\u003c\/strong\u003e\u003cbr\u003e\nPair them with a 1S flight controller whose ESC can handle the current. The Matrix 1S 3IN1 and 5IN1 II, both with 12A ESCs, are BETAFPV's recommended partners for these motors.\u003c\/p\u003e","brand":"BETAFPV","offers":[{"title":"Default Title","offer_id":53104953524504,"sku":null,"price":55.88,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0948\/1122\/6392\/files\/1102_Brushless_Motors_2026_4PCS_540x_56d1c370-c663-48bb-9abf-7418a434f036.webp?v=1793500902","url":"https:\/\/launchpadfpv.ca\/products\/betafpv-1102-brushless-motors-2026-21000kv-1s-4-pack","provider":"LaunchpadFPV","version":"1.0","type":"link"}
