Astro Max Spare Propeller Set (2270 High Efficiency)

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. 

Astro vs Astro Max Props

The Astro is equipped with Freefly F45 motors, where the Astro Max has a newer Freefly 7010 motor. In addition to providing more thrust than the prior generation motor, the Astro Max 7010 motors have a different mounting pattern for props than the F45 motor. It's easy to identify which motor you have visually, just check out the image on the page that shows both motors.
