Master Airscrew Performance 6x3.2 Multi-Rotor Series 2-Blade Propeller - Normal/Tractor/CCW

I am usually the guy to buy cheap props for my small copters because I beat them up so badly. I just recently built a new larger bird and decided to spend a few extra cents on better props. I had ordered a XOAR PJP set, and an off brand carbon fiber set along with these all in 12x4.5. Not only were these the best price, but they also functioned the best of the three. These props showed a significant near 2 minute increase in flight time over the others purchased. Not to mention They look good, balancing was reasonable, and the build quality is better than you would expect for this price. Highly recommended.

I used to buy Master Airscrew props when I was a kid. This is the first one I bought after near 30 years and I was not disappointed. This prop is well made and very light (quadcopters are very sensitive to the weight). It has much more twist compares to the other props with the similar size. The twist is very close to the ideal twist that produces uniform downwash with minimized the drag/torq/power. It has about 10-15% more efficiency to the other props.

I have always been a big fan of Master Airscrew props. Good solid quality, well balanced right out of the bag, and good performance.

Looking for props for a new build of a Tarot 650. I was limited by the fact that I had 30 TY-Motor 2212s in stock and wanted to use them. After running the numbers on E-calc the 12x4.5s looked to be the best option but most importantly they were in stock on Amazon. Performance was very good and the only complaint is that there were no shaft adapters included. Luckily I was able to take some Gemfan adapters and ream them to the required diameter. Vibrations were lower out of the box (I have not yet balanced the props) and the craft handled very well. I'll be buying more for my other copters with the 2212s.

Works great on my BMJR Spacewalker. Running an Axi Gold Line 2208/34 on a 3s it has good low end power.

I thought it was a 12x4 propeller for airplanes but it would not fit on my way airplane because of the chord of the propeller. Of course the other propeller is a pusher.

These propellers are pretty nice. They provide a good amount of lift and when reamed can be used as a replacement for the Turbo Ace x830 drone. These are actually much more durable than they look and work pretty well. The only thing of note is that these are a little bit wider than expected (not really an issue).

Work great for my quad on 800kv motors. Online simulator I used indicated that a higher pitch would be a bit more efficient on this build, only one I could find was from a popular three letter brand that was 12x5.5. That same simulator indicated that the other brands props were more efficient than Master Airscrew's, though it didn't list Master Airscrew's MR specifically. Anyways...after testing, running the same routes at the same speeds...these props are more efficient than the popular 3 letter brand even though their pitch should have been a better match and they supposedly were the most efficient MR prop. In my case, these are the most efficient I can find on this motor frame combo. Durable too, 8ft fall landed perfectly upside down...only one prop had any breakage, still worked though.
