I am satisfied with how Master Airscrew responded to my problem with the MA2 props and recommend them if you are looking to reduce your sound signature (drones should be seen and not heard).
January 13 - Sent email describing problem.
January 14 - Received reply, asking if I wanted a refund or replacement. I asked for replacement. They did not ask me to return the defective blades.
February 3 - Replacement props received.
February 4 - I tried them out. Visually they look great (no fur on the edges).
For 31 minutes I hovered in place in my living room, with the drone aimed at a spot on the wall. The drone was steady the entire time.
The sound is a much more pleasing lower pitch and, to my ears, perhaps 2/3rds as loud as the OEM blades.
I just took it out for a twenty-minute flight. The drone is stable. The problem is resolved.
Best,
Math
