The prop is an 8x6 in 3-blade which should be approximately equivalent to a 9x5 2-blade prop. The motor that's on the flying wing is a 950 kv speed 450 outrunner and eCalc predicts it should produce approximately 130 Watts +/- 15%. I chose this prop over a more efficient 2-bladed prop for its increased ground clearance and for its durability. APC props don't survive ground strikes. The prop makes for an interesting looking wing. Now I just need a matching spinner.

Same as the other Reviewfor prop adapters

You just can’t beat the instant power gains from these props. Highly recommended.

Really really love the performance gains MAS props give you. Very efficient props

This was the other side of my C47, I needed smaller three blade counter rotating props with differential thrust. This prop combo worked a treat.

Very nice props!!! High quality. Didn't need much balancing, and they feel very "solid", yet not too heavy. Will definitely be ordering these again when I need replacements...

master airscrews are the only props I use can"t beat perfarmence.

Good quality prop but the three business day delivery was bull. I am a new account so maybe that delayed my order but taking my payment was instant. We'll see on my next order. But the quality of my purchase is what is important.

looks good on my Royal B17. No pictures yet.

i wanted a prop for a dynam plane which uses a prop that has a recess for the a nut that when the prop slides on the motor shaft ,an over the nut is locked in place. the new props i bought do not have this.to make it work i would have to pressure fit the prop with a self locking nut on the inside an outside of the prop.i was told they would work. maybe i could use them on another plane in the future. thank you

Great service and price. My first experience with 3 bladed props. Thanks, Emil Richter

Knowing what I need is one thing, but locating it is another chore. I had never hard of Master Airscrew, but easily and quickly found what I needed in its inventor. I placed my order on a Sunday, and it was delivered the following Friday. Good job

Perfect

Excellent prop. Well made. Came balanced.

great props

This 3 blade 8x6 prop performs fantastically on my Durafly EFXtra in 4S mode. However there is a .186ID x .176 deep CBore on the motor side of the prop leaves no engagement on the smooth part of the 6mm shaft when using a spinner. The .375OD reducers provided only fit the front C.B. engaging only the smaller threads. The other MAS props have no C.B. on the back side, as it should be. Andy

Amazing quality, detail and strength! Thanks

This Set is great and works great for my Catalina!! Dtan

Fast, smooth, no hassle great service!

Great products and amazing service

Got it quick. Thanks much.

Dynam Grand Cruiser Great product

I have always liked Master Airscrew props due to their consistent performance. However, almost every order I receive has at least one prop that has an improperly milled hub, mainly material that should have been removed but was not. Needless to say its quite a challenge gouging the material out of the limited space of the hub. Again, the performance is great. Improve your quality control and you'll get 5 stars from me. Mike G

Got 6 all were balanced as sent. Received them in just a few days with e-mails that kept me updated on when I would get them & when delivered Great service David

mounted without difficulty & looks good thanks for the product you developed FRANK

Put it on a Dynam C47 and she flew great.

excellent product with extraordinary packaging

My Brother in law and I both fly foamies and have used many of your props. Needless to say we have been very satisfied with everything. The props themselves, the selection, the service, the price, all are outstanding! Thank you for a great product.
