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.

if you have 2207 or 2208 motors and have problems with other props on these sizes this is you’re answer especially on the glide frames were you can run 5.1 props gemfans my new favorite
It’s like HQ V1s 4.3 meets Ethix S4. A noticeable improvement in top end power over a 3.8 pitch prop, still very smooth footage on the go pro and super responsive. Flight time was within 15 seconds of the same rig running ethix S4 props. Really a must if your running over 700g AUW and need a little more pop or hang time on your freestyle runs. The smoked grey / black color disappears pretty good for those that have props in view, personally I love the neon yellow 🤘
The blade quality is very good. Very balanced and flexible
