Machined from aluminium rather than moulded in plastic, it offers a more rigid connection between servo and linkage, which matters most in high-load setups such as steering, throttle, and control surface linkages. At 4 inches in total length, it suits builds where extended throw or precise geometry is needed.\u003c\/p\u003e\r\n\r\n\u003ch3\u003eKey Features\u003c\/h3\u003e\r\n\u003cul\u003e\r\n  \u003cli\u003eCNC machined aluminium construction provides greater rigidity and resistance to flex compared to standard plastic servo arms\u003c\/li\u003e\r\n  \u003cli\u003e25T spline fitment is one of the most common servo shaft patterns, compatible with servos from a wide range of manufacturers\u003c\/li\u003e\r\n  \u003cli\u003e4-inch double arm configuration allows linkage attachment on either side of the servo shaft, useful for symmetrical or dual-pull setups\u003c\/li\u003e\r\n  \u003cli\u003eMachined finish ensures consistent spline engagement and a secure fit on the servo output shaft\u003c\/li\u003e\r\n\u003c\/ul\u003e","brand":"Dual Sky","offers":[{"title":"Default Title","offer_id":49762734604525,"sku":"DSA-21779","price":31.95,"currency_code":"NZD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/2194\/5657\/files\/Dualsky_servo_arm_full-double_12e4f809-20cc-4291-a80a-06a94f42bfea.jpg?v=1776131691","url":"https:\/\/www.hobbycity.nz\/products\/dual-sky-dsa-21779-sa-4-0-25t-cnc-aluminium-4-inch-double-servo-arm","provider":"Hobby City NZ","version":"1.0","type":"link"}
