thank you for the very prompt shipping and delivery of my propellers. My Plane seems to have more power and flies better with your design of the blades than anything else I have used on my plane!
great props''
Same awesome performance, now in fun colors!
Great price Great product
Almost perfectly balanced right out of the box. Perfect for my 10” custom RTK build. MAS will be my exclusive prop dealer from this point on!!!!

Great and thoughtful Service!!! Thanks!!!
great service, promt delivery, good product
For the airframe sizes I like to build, the MR 8x4.5 is the best prop I've ever flown
We needed replacement props for the drone that we are flying. The Props showed up in time for the demo that we needed them for so thank you.
These are props I bought to replace ones that were damaged due to a crash. I bought the white ones because I was concerned that the black ones might get damaged from the Arizona sun, when the Quad Plane was sitting on the ground for long periods of time. These props are the absolute best I have tried for a Hex copter, Quad Copter, and Quad Plane. They are balanced, and the most efficient props I have used.
These are great props for my T Copter. The have good lift and add to the flight time. I order different colors to help with orientation of the copter. Pick yourself up some and you will enjoy the flight. thanks, Mike
Great prop right now using for testing
Replaced the stock Chinese props with master props. As any drone tuner knows, prop balance is very important. Master props were well balanced out of the box and no drone tuning was required. The drone is slightly quieter and I’ve gained about 10% more flight time.
Great propellers, very well packed
I've standardized on the MR 8x4.5 prop for my hotliners. Testing proves that they generate more thrust than the APC MR series of the same size. And of course they are better looking! Hopefully I can start buying single props instead of pairs. I've got more "pushers" than I'll ever use.
Great Propellers... they seem to bite more air... i get better thrust reading with MA props than any other propeller I've used. I would suggest propeller makers to design and sell propeller shaft reamer in SAE/metric.
Awesome props well balanced for your 9-in build
I was trying to maximise a motor prop combination for one of my birds, and happened upon your MR series props. I couldn't be more pleased.....easy launch, lots and lots of power, and she'll glide dead stick like a cub...The chase video was shot using a racing drone with a top speed of ~ 60 mph....I kept the Not Quite at ~ half throttle except for the entrance to and the exit from the Cuban 8, once just to run off and leave the chase drone. Consensus is she's an 80+ mph hotliner.....probably not up to pylon racing standards, but she's quick, easy to fly, and no bad habits....Fit my needs perfectly. I do wish you would send eCalc the P and T constants for the MR Prop.
We have a Twin Timber and we are going to use the plane for glider towing. With the new propellers it has unlimited climb. It fly's slower over all but the climb is amazing. I had no idea I bought drone propellers and they work!!! Thank you, Master Airscrew,
Great little prop,great price!!
Prompt delivery. Excellent products.
I've been buying master aircrew propellers for years, will continue as needed, hope they continue to make the colours I want
Worked great with a T-motor F90! Way better than their proposed propeller.
Awesome props for the latest 8-in build thanks
Very efficiente props
The efficiency of the propellors made the difference. And made an experimental VTOL project of 4 years to a success.
I use these propellers on all my drone builds. They had never let me down. Well made and balanced out for the box. I'm trying them on this new Franken Build Drone using a pantom 3 shell and high performance motor. 👌
This is very good propeller
good performance
Great props I use Master Airscrew with all my aircraft
My go to props
Great store to shop at
Bought these to replace the stock Walkera props on a Walkera Tali H500. I needed to ream them out to fit the motors, but other than that they work great. I checked the balance of the props and they were all well balanced. I will be buying some more for my other Hexacopter.
Good looking quality props only had a hover test in front yard but they’re fine as expected
Awesome props and great quality...I am impressed!
