Love these for use on scale multi engine models, so counter rotating props are possible. As a bonus they also provide excellent thrust and a quiet, pleasing sound. I gotta say, though, that I miss the old logo on the blades that looked more like a scale marking.

Sorry, brain fart! Looking for highest Watts/Pound for each prop to find out which prop set will create most lift. Need a number between 90 or higher for proper flight. Dwight

Haven't installed yet. Still building. Well made product

Jeffrey B.

Used on a powered glider, upgraded from a 10 x 6, 2 blade. Works great!

Richard M.

After some on line researching I concluded contra rotating propellers was the way to go so I'm changing the two right propellers from tractor to counter rotation

James J.

Hard to balance, i need a 9,in pusher for a saito that runs ccw.

great products, prices, company

These props are a high quality product and all future prop replacements on all of my collection will be from Master Airscrew. Although my current project has not flown yet, I tested the props for balance and vibration and they passed with flying colors! Literally! The Chicom props I tested would probably shake the nacelles off the wings. This is a vintage Royal B-17F and will be ready to fly in about a month. The plans had a prop scale which indicated a 10 x 7 prop but after receiving my order, the 10” props would hit the fuselage. I reordered 9 x 7 props and contacted Jenny at MA and returned them for prompt credit.

ONCE AGAIN, BEST PRODUCT OUT THERE

Jay M.

Well made, well balance, efficient and light weight. Fast postage, much appreciated.

Alan M.

Taxi tests appear to show these props are giving enough thrust to allow for take0ff

Alan M.

Loads Turnigy Park 450 - 890 Kv motor fairly well to give over 800 grams of thrust.

Great product Just what I needed Superb customer service Lightning delivery Thank you

John R.

Great propellers, have been in my hangar for a long time. Looks good on the HK B17.

Donald C.

Great great prop works perfect on my flight line B-24 for from motion

John R.

Great product, as allways. Using this prop on the Flightline B24, should improve ground clearance. John

Seems like a decent propellor. Haven't had a chance to fly it yet. Only real issue I had was fitting the adapter ring into the prop. There was flashing in the molded recess in the prop that needed to be cleared out plus a ridge around the ring that had to be chamfered to get it started in the prop.

Steven H.

Master Airscrew 3 blade props are awesome! They are quieter and have a more pleasing sound than most any 2 blade props, and they produce tremendous thrust. Plus the scale like looks are nice for aircraft that have 3 blade props in the full scale version.

William K.

Prompt service and excellent product! Would recommend without reservation.

BILL P.

GREAT PROP AND FAST SERVICE THANKS

Richard W.

I like to experiment, learning new lessons along the way with each new project. I haven't a better propeller than the Master Airscrew for my "scratch built" airplanes. Always very well made, excellent quality, solid ( I need that! ) and consistently dependable. What more can you ask for? Oh yeah, great price and excellent customer service! Watch the video: https://youtu.be/AdSLMS9FQsg I hope you enjoy it, as much as I did making it... ;-)

Thomas A.

Enjoyed doing business with you over the phone. My order arrived on time, and in great shape. However, the blades are out of balance, and I am in the process of balancing them. You have my business, and I will let my club members know that your company is a good place to order from. Thank you, Thomas Armstrong

Larry M.

have not used it yet

David K.

I've ordered these before and the newest version is the best! Required just a little work to balance. Greatly recommend.
