The collet is available with 2.0 mm, 2.3 mm, 3.0 mm and 3.17 mm bores for all common motors.\u003cbr\u003e\nThe impeller was designed for the Robbe Power 330 motor, with which it produces approx. 200 g of thrust with 8 (small) cells.\u003cbr\u003e\nIn terms of strength, the use of powerful brushless drives, such as those offered by Lehner, Hacker or Astro, is also possible without problems.\u003cbr\u003e\nSince the impeller operates at very high speeds, we recommend using motors with ball bearings, such as the MPX Permax 280 BB. For batteries, GP 1100 cells are sensible for single-motor models, and especially GP 2200 cells for twin-motor models.\u003cbr\u003e\nThe impeller is supplied without an intake ring. The intake must therefore be provided on the model.\u003c\/p\u003e\n\n\u003cp\u003eThe optimal nozzle should have a diameter of approx. 40mm.\u003c\/p\u003e","brand":"WeMoTec","offers":[{"title":"Default Title","offer_id":53449015427415,"sku":"WMC001-3","price":19.9,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0935\/8318\/0119\/files\/WMC001-3_b1_f6270b2f-827c-4c4c-8e05-9e3d2de047ee.jpg?v=1779913793","url":"https:\/\/hoelleinshop.com\/en\/products\/micro-fan-fur-motoren-mit-3-17mm-welle","provider":"hoelleinshop","version":"1.0","type":"link"}
