This is part of the new lineup of Gemfan props. Tracking with the design language of the extremely popular 51466, Gemfan brings us a 3.9g prop that has a slightly lesser pitch and slightly less weight. The result is a prop that should be a bit more responsive with similar overall speed and easier overall throttle management.
There are a number of props in the same category as this prop and all of them are really fantastic. Gemfan 51433, Nazgul 5140, DAL Nepal 1, HQ S3, 4, and 5. Of these. The 51433, Nepal 1, S4 and S5 are extremely similar with the Nepal and Gemfan being a little more efficient overall. The flight feel between them all is very close and you will need to try them to decide which you prefer.

Awesome, AWESOME PROPS! They're my 3rd favorite props! 1st are the HQ s4 & s3's than 2nd are the new gemfan 5133 props! But I highly recommend these WindDancers great for freestyle!! U won't be disappointed!!
I would say these are very similar to S3 but way more efficient. They are now my main prop for my 5" ApexHD with Steele Stout motors 6S rig that weighs ~580g. Really like smoke up front and neon yellow out back. Another bonus with Gemfan is they have better flexibility in winter than HQ/DAL/Azure.
I'm waiting on other parts to complete my build so I have not tried these propellers I am sure they are excellent Like everything else I bought from FEV cycle So go ahead and buy a set I'm sure you will not be disappointed I will write a complete review when I have finished my build and flown These props
I have tried alot of different props in the past few months, this prop is the best out of all of them. I think the fact that it's light weight is a huge factor. It gives the motor that chance to really make the prop sing and its voice is quiet but powerful. Full throttle resolution from the mid teens to 100% - Surprising efficiency. My lightweight 587 gram auw 5" Quad can easily do 10 minutes of cruising and 8 minutes of spirited flying on a 5s 1500 mah lipo. I definitely recommend you try everything Bob recommends. He knows what he's talking about.
