Astro Max Spare Propeller Set (2270 High Efficiency) is a matched CW/CCW pair with pre-mounted hubs. New 22″ blades boost endurance ~10% over 21″ 2170 props. Factory balanced for quick swaps and reliable performance. For Astro Max only; do not mix with 2170 props.
Astro Max Spare Propeller Set (2270 High-Efficiency) replaces worn or damaged props with a factory-balanced, matched pair—one clockwise (CW) and one counter-clockwise (CCW). These new 22 in high-efficiency blades deliver roughly 10% longer flight time than the previous 21 in Astro Max props. Each blade is pre-mounted to its hub; swap the whole assembly for consistent pitch, balance, and reliability.
Upgrade Guidance
- Already on 2270: buy any number for spares (most teams keep one set: 1×CW + 1×CCW).
- Upgrading from 2170: purchase two sets to convert all four motors; consider a third set as a spare pair.
- Replacing a single prop on 2170: you still need two sets to upgrade the aircraft—do not mix 2170 and 2270 props.
- Promo: add two High-Efficiency (2270) sets to cart and the second set is discounted automatically through December 31, 2025.
Key Notes
- Designed exclusively for Astro Max motors—not compatible with original Astro.
- Do not mix 2170 (standard) and 2270 (high-efficiency) blades on the same aircraft.
- Check markings on the blade: “2270 CW” or “2270 CCW.”
- Refer to the Astro Maintenance Manual for inspection, torque, and installation procedures. Blades are matched/balanced as a pair—do not swap individual blades between sets.
