I have nothing against Master Airscrew props, if they are not the black ones.
I learned many, many years ago to stay away from these.
Not to argue and I don't know what the quality of MAS was many years ago but the current crop of MAS props are perfectly suited to training new pilots, scale and general sport flying. I haven't had a bad one yet.
I agree MAS is not for high performance.
Maybe it is time to spend a couple of bucks and re-evaluate them.
