Frame I-flight 383 mm, motor T-Motor 2216-9 1100KV and Rush 60 amp flight control stack.
Best performing and manufactured prop of this style I have found.
Factory balance is spot on, excellent manufacturing and quality control.
During flight they provide great lift and low noise.
I also liked the relail packaging.
You can't go wrong with these props, no doubt the best you can buy.

The best 9 inch Tri-Blades on the market. Quiet, smooth and powerful.

Fast shipping!! What a great prop, miles ahead of the hq I was running before. 10/10 would reccomend!

These are my favorite props for 9" quads. Super smooth and fast throttle response.
Roy R.
Exactly what I wanted and works great.

Always the first choice for props.

Best 9" Props! You know why? Balance balance balance! Also these are significantly lighter than the HQ prop 9" macro props. Less pitchy, but plenty of power believe me. I can hear/feel them flattening out a little on full throttle with my BH Tornado T5s which are monsters, but they hold up just fine and can support a DSLR camera payload (while doing powerloops lol). They are also muuuuuuch less brittle than the HQ props and they have enough flexibility to not just snap if a the quad has a rough landing. Thank you for making these and please continue to do so!

Excellent product! Powerfull, Control, Silent and smooth video. Much better than the 1045 props I used before. Because these props are factory balanced, you experience less vibrations and smooth video results.
Thank you,
Marco

In 2019 i completely rebuild and upgraded a Walkera Scout-X4 to a Scout-PX4. Everything was perfect but something was missing. The thing that was missing was extra over capacity in thrust and therefor flight reliability . I experimented with different propeller setups but did not succeed to find the right setup . Until i got my first set of MR3's , these propellers are perfect for my setup !. Very nice sound , 30% more thrust than original and the propellers are really a pièce of art in build quality and appearance. I bought myself a second set of 4 already ..i would not want to run out these ever !.

Nice and beautiful tri-blade propeller.
Almost perfect in balance,just a little adjustment on two of my four propps,
and that was it.(Thumbs up).
And very good customer service.(Thumbs up).

Building an S500 with X class hardware for a stable, long range camera platform. Wanted large, vibration free props for hovering and filming at <50% throttle. I was hoping to find 11” props, but these 9” props produce 800g of thrust at 10 amps (4S), same as my 12” props.
The factory balance was perfect. Typically I spend hours balancing a set of props. Factory balance is well worth the price!
Michael D.
The props are well made and the finish along with balance is great. I would like to see this same size hub thickness and shaft diameter in a 10" prop. Very happy with the performance so far.

These props are supposed to be good, but selling them without adapters is just poor business practice.

Been buying MAS propellers and recommend it to my friends. With higher airflow rate, the speed of our drones are much faster.

Absolutely my favorite FPV drone and probably because of the propellers. I used every 9" prop out there and nothing comes close to the smoothness the MR-9x4.5x3 props brings. I think alot of it has to do with the fact that they come perfectly balanced from factory. I hate balancing props myself. At first I thought they felt a little soft and 4.5 on pitch would be slow. I was wrong. The don't flutter or flatten out at all like soft props sometimes do. Because they are so light weight and 4.5 pitch they accelerate and decelerate very quickly making the drone extremely nimble when doing proximity flying and the top speed is still very fast. My quad does over 100mph with BrotherHobby Avenger 2812 1115kv motors on 6S and turns on a dime. For my 9" FPV drone I'm done shopping around trying to find the best prop. I found it and it's the Master Airscrew MR-9x4.5x3. Now if MAS could please make a similar MR-10x4.5x3 or MR-10x5x3 propeller I could finally be happy with my 10" race drone too.

I use masterairscrew props on all my quadcopters. The best props ever!
Hugh P.
Great product and service.
Vince P.
Nice looking props. Took very little to get perfect balance. My Quanum Venture flies noticeably smoother with these props.
Rickie B.
Very good and quiet propellers.

Very good and quiet propellers.

I like the 3 blade props a lot, but I would like to have a 10 inch 3 blade.
Randy B.
These are great props, smooth and quiet very good control.
I am just getting into the XClass drones. I would love to see some props from MA for this class of racing.
Amiud M.
The best propellers ever!
Amiud M.
The most balanced props ever. I use nothing but masterairscrew!
Vince P.
These are good looking props. They needed a little balancing but perform well. My 430 size quad flies well with them.
Andrew H.
At last found some good quality 3 blade propellers but I do think for the price of these props they should be finished a little better. Both leading and trailing edges had sharp molding marks. It was easy to fix and I will be buying more. Is there 8 inch 3 blade MR3 available.
Brandon L.
Great prop, especially light. I would be interested in larger diameters of this same family of 3-blade props (10"-12" would be useful). I was able to get 540g thrust @ 22V,80W input power. Additionally would be great if the prop came pre-drilled with a simple 2 through bolt pattern to mount direct to common motors.
