I was curious too about the reference to "installing the MAS set on my
mini 2" so I Googled "MAS Set" and came up with this web site to
Master Airscrew…
Quality UAV Drone and Model Aircraft Propellers designed and manufactured in the USA since 1978. Extensive range of R/C propellers for racing, DIY models, professional and consumer drone upgrades for DJI, 3DR and GoPro UAVs.

They certainly sell some Colorful Propellers… and they make some very specific claims: Quieter (Stealth…), More efficient (Power Reduction…), Longer Flight Time (From Efficiency…), Better agility, More Speed, Less Weight, Improved Safety, and 100% Compatibility…
Your references to your
Mini 2's strange behavior seem to tell a different story concerning the 100% Compatibility claim…
Additionally, I find it incongruous that they calm "Stealth" yet brag about the Vibrant Color options for Better Visibility… When I think of Stealth, I imagine a Ninja traveling "imperceptibly," but I cannot imagine a Ninja wearing Flaming Red or International Orange being very Surreptitious in Sunburst Yellow…
I recommend you contact
Master Airscrew about their Refund Policy…
PS: What do you mean by "fish bowling at low altitude?" I cannot find any reference to this relative to flying; plenty of references to: Group Discussions, Car Windows, Smoking Pot in an Enclosed Space, etc…
