Freefly Replacement Propeller Set for Astro Max Drone

This set includes two replacement Astro Max propellers (one clockwise, one counter-clockwise) and fasteners. These props are 22" long unfolded, providing a 10% increase in efficiency and flight time over the prior 21" Astro Max props.

How many of these do you need?
• If your Astro Max already has 22" props marked with "2270", just purchase what you feel comfortable having for spares. Most people have one set (one each CW & CCW)
• If you want to upgrade your Astro Max to maximize flight time, you'll need to purchase two sets of these new props. Plus maybe a third set to have a spare pair in your kit
• If you just need a replacement prop (CW or CCW) and have 21" props on your Astro Max marked with 2170 on the blade, you'll need to purchase two sets of these new props so you can replace the props on all four motors
• If you have an Astro, not an Astro Max, these will not fit on your drone

Note:
• Not compatible with original Astro motors
• Cannot be mixed with other versions of Astro Max props (2170 props)
• See the Astro Maintenance Manual for instructions on inspecting and replacing propellers
• The propeller blades are a matched and balanced pair (i.e. the clockwise blades are a pair) and are pre-mounted to the hub. Do not replace individual blades
