We performed some really dumb tests indoors (don't do that), and some side-by-side tests outside.  Overall we are happy with the Master Airscrew props and feel it gives excellent lower RPM power to the platform!  Not a bad purchase at $20, but definitely be aware that the drone is still noisy.

Is it safe to use this Propellers?

Is it safe to use this Propellers?

Hello and good day Bo3waas. Thank you for reaching out. Actually, there is a possibility that the Master Airscrew Stealth Propellers will be able work on the DJI Mavic Air. However, since it's not yet optimized and tested by DJI we cannot guaranteed the stability of the Master Airscrew Stealth Propellers if it will work all the time with no issues while using the DJI Mavic Air.  Just a friendly reminder that  it is recommended to use the original propellers for the DJI Mavic Air for compatibility and reliability. If in case of damage caused by the third-party propellers to the said drone. The warranty of the drone might be void. Thank you for your understanding.

has there been resultant incident affirmed attributed to such propeller change?

Thanks for sharing

Great video with lots of valuable information -- although Ariane could probably host by herself, she's a natural.  Pretty and articulate -- born for the screen.  Then there's John...let's just say he has a face for radio.  It almost looks like a kidnapping.  What a mismatch.  May I suggest he wear a beekeepers hat or something similar for future shows?

Just kidding John, you know you're a lucky guy.  Awesome job, you two (Ariane mostly).  I really enjoy your videos, keep up the good work.

They were working great for 10+ flights until I got the motor current error while flying. Why yes, I did adjust the gain to 80 in case you were going to ask. It WAS windy that day

I emailed Master Airscrew, they have not responded with an answer

Oh wow, I agree with you 100%!  She is a natural and just drags me along for the ride!  Behind every great woman is a dopey guy hanging on for dear life!

I too saw a motor current error on a very windy day; that's good info about adjusting the gain to 80!!

That comment is hysterical!  And true!

You're a good sport, John.  

You guys are the best, looking forward to your next production!

I bought them also. havent fly with them yet. They seem super flimsy though.

A pal has a MK1 Pro with aftermarket low noise propellers.. Whilst there is a minute, barely discernible  difference in pitch between his and my Pro2 I really dont think it's worth even contemplating spending money on 'low noise' props for that purpose alone.

DJI approved props for me all day plus its fun scaring little furry animals

It all depends on what 'the boss' says we are going to do!    She is firm, but fair!

We want to nail down if these props have any performance gain; we are working on tests that are comical at best, but might give some further insight!  I do agree with the furry animal scaring; it is a wonderful sound to hear the drone scream up over a ridge, I can almost hear 'Ride of the Valkyries'.

I've used these props exclusively for about 20 batteries now.  I can't say enough good things about them.  Yes, they reduce the decibels and they lower the frequency of my MA - both very welcomed changes.  I guess the part I like the most is the improvement in efficiency.  I usually fly until I hit around 30% and then begin coming in for a landing.  I'm not a guy who wants to lose his drone because I pushed it too far.  With the stock props, I averaged about 20,000 ft per flight.  With the MAS props I average about 24,000 ft.  That's a 20% increase in efficiency.

I will get the current errors if I have it in sport mode and both sticks pushed fully forward.  As long as I back off on one of the sticks, the errors won't happen.  I've also noticed that the batteries aren't as warm when I land.  That could be me imagining it (I have no real metrics) but it seems consistently a little better.  I can't see that I'll be returning to the stock props.
