Tech Specs: New geometry and longer blade for 10% increase in flight times Diameter: 21.8 inches (554 mm) Marked on the blade with "2270 CW" or "2270 CCW" How Many Sets Do You Need? Choose the option that matches your current setup: I already have 22" props (marked "2270"): Just buy what you need for backups. Most pilots keep one spare set (1 CW, 1 CCW) in their gear. I want to upgrade from 21" props: To maximize your flight time, you'll need two sets to replace all four propellers. We also recommend grabbing a third set to keep as spares. I need to replace a broken 21" prop (marked "2170"): You cannot mix and match prop sizes. You must purchase two sets of these new 22" props to swap out the propellers on all four motors. I have a standard Astro (not Astro Max): These propellers will not fit your drone. You will need to purchase the standard Astro propellers Compatibility: Freefly Astro Max
