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.
