A bench check lets you see the available movement and neutral reference before choosing how the servo will sit in the model.\u003c\/p\u003e\u003cp\u003eArrange the horn and linkage around the intended task, leaving room for the mechanism to move without binding. The SG90 is a small positioning servo, so match the load and travel to its actual specification rather than forcing the linkage against a stop.\u003c\/p\u003e\u003cimg src=\"https:\/\/ae01.alicdn.com\/kf\/S7308249095454560b79be73e9eedf282r.jpg\" slate-data-type=\"image\"\u003e\u003cimg src=\"https:\/\/ae01.alicdn.com\/kf\/S7ee3c87e189d4f55a24e74a489e5972bD.jpg\" slate-data-type=\"image\"\u003e\u003cimg src=\"https:\/\/ae01.alicdn.com\/kf\/S3962c988d8734b49b20cef26b686c0378.jpg\" slate-data-type=\"image\"\u003e\u003cimg src=\"https:\/\/ae01.alicdn.com\/kf\/S7db0c94a4e9648fda10df7c28410272bb.jpg\" slate-data-type=\"image\"\u003e\u003cimg src=\"https:\/\/ae01.alicdn.com\/kf\/S6893c8671cd84b7c8d621e53fe13bbabI.jpg\" slate-data-type=\"image\"\u003e\u003cimg src=\"https:\/\/ae01.alicdn.com\/kf\/S6acbf7253247497db48762ed2ff4ce19r.jpg\" slate-data-type=\"image\"\u003e\u003ch3\u003eTechnical details\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eSG90 9g-class micro servo; 180-degree specification\u003c\/li\u003e\n\u003cli\u003eServo tester with manual, automatic and neutral modes\u003c\/li\u003e\n\u003cli\u003eFour-AA battery holder with JR connector\u003c\/li\u003e\n\u003cli\u003eActual selection: one kit\u003c\/li\u003e\n\u003cli\u003ePrepare suitable AA cells and confirm the permitted supply arrangement\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003e\u003cstrong\u003eBring the servo to the bench and plan its movement before finishing the model.\u003c\/strong\u003e\u003c\/p\u003e","brand":"Spy-shop.com","offers":[{"title":"1 kit","offer_id":63962936770890,"sku":"1005009934751595-1 kit","price":26.82,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0764\/5980\/2954\/files\/S7308249095454560b79be73e9eedf282r.webp?v=1792256264","url":"https:\/\/spy-shop.com\/products\/servo-motor-tester-kit-sg90-9g-micro-servo-180-degree-rc-micro-servo-tester-controller-with-power-supply-case-4aa-battery-hold","provider":"Spy-shop.com","version":"1.0","type":"link"}
