I caught some questions regarding Master Airscrew props in another thread and didn't want to hijack it. I've got a set of these in my Amazon "save for later' bin as they looked interesting. I've had a M2 Pro for few (several?) weeks now and still have the original props on and have a full set of 4 replacements on hand. The MAS props look very interesting, especially with some neat colors. Should I need to replace a set, are there reasons that I should or should not use the MAS props instead of the DJI props?
