Master Airscrew Stealth Propellers Mini 3
Score: 70/100Rankings

Master Airscrew SUPER STEALTH propellers for the DJI Mini 3 Pro/4 Pro deliver up to 37% noise reduction and a modest 2% flight-time boost (about one extra minute). Constructed from glass-fiber composite with a glossy finish, they are US-made but limited to newer Mini models and lack a screwdriver.

The Ruko F11 series replacement battery offers a solid 28-30 minute flight time in a lightweight 193 g package with built-in safety features and fast USB-C charging, but it lacks an included charger and may suffer from swelling over time.

Professional reviewers highlight the battery's seamless integration with Ruko's ecosystem, noting its compact, lightweight form factor and smart BMS that safeguards against over-charge and over-discharge.
Everyday users appreciate the reliable 28-minute flight time and easy swapping, though some report occasional defects, swelling, and the inconvenience of having to buy a separate charger.

“Lasts the full 28 minutes as advertised.”

“Easy to swap - great for back-to-back flights.”

“LED lights are accurate and help avoid sudden power loss.”




Professional reviewers highlight Master Airscrew's long heritage and focus on acoustic optimization, noting that the SUPER STEALTH blades use refined geometry and a glass-fiber composite to cut sound power by up to 37% while delivering the same thrust at lower RPMs.
Everyday users overwhelmingly praise the dramatic noise drop, the plug-and-play installation, and the premium look of the glossy finish. Complaints centre on occasional balance issues, the missing screwdriver, and the perception that the modest flight-time gain may not merit the price for occasional flyers.
