Score: 68/100
Master Airscrew Stealth Propellers
Score: 76/100Rankings

Master Airscrew's STEALTH propellers for DJI Air 3/3S provide up to a 5% increase in flight time, modest noise reduction, and exact fit with vibrant color options. The modest noise improvement and limited technical specs are drawbacks. They are great for users wanting a slight endurance boost and personalization.

The Gouduoduo2018 FPV Drone Gimbal Bumper shields the DJI FPV gimbal with durable aluminum alloy bumpers while adding just 9 g. It does not protect the rest of the drone and may slightly obstruct the camera if misaligned. Ideal for FPV pilots seeking lightweight gimbal protection.

Professional reviewers acknowledge the STEALTH propellers deliver a tangible 5% boost in flight time and enable higher sport-mode speeds, while praising the exact fit and aerodynamic design. However, they criticize the modest 2-3 dB noise reduction, noting that in some tests DJI OEM props were marginally quieter, and they point out the absence of detailed technical data.
Everyday users generally like the precise fit, the quieter-than-stock feel, and the extra speed in sport mode, especially appreciating the color options for personalization. The most common criticism is that the noise reduction is less dramatic than marketing suggests, and some wish for more spec details.
