Master Airscrew Stealth Propellers
Score: 76/100Rankings

The Holy Stone HS720R Intelligent Modular Battery provides a lightweight 110.8 g power source delivering up to 26 minutes of flight time, featuring an intelligent BMS for safety. Its main drawback is the lengthy five-hour recharge cycle and reliance on the original USB cable. Ideal for HS720R and HS720G pilots seeking a portable spare.

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.

Professional editors consider the HS720R modular battery a solid, reliable power source that lives up to its advertised 26-minute flight time and adds minimal weight. The intelligent management system and safety protections are repeatedly praised, though the lengthy recharge cycle is seen as the primary downside compared with higher-capacity alternatives.
Consumers consistently praise the battery for its lightweight form factor, easy installation, and the noticeable boost to flight time, describing the experience as enabling smoother, longer aerial footage. The main frustrations revolve around the slow charging speed and the need to use the original USB cable, with occasional reminders about proper storage to avoid swelling.

“stunning aerial footage”

“seamless flying”

“fit really really well”



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.
