I bought the 5 blade props specifically to see if they would add more thrust to the NEO so that it could support the extra weight that the added bottom light (40g), the top mounting bracket (~16g), and the penlight (20g) added. With the stock 3 blade props the NEO kept making sudden drops in altitude, but with the 5 blade ones it flies smoothly with all the extra weight.
There´s also a 4 blade version from this prop. If the load isn´t so heavy. these have a little longer flight time. I use them, when the weather is a bit windy. The Neo flies more stable, than with 3 blades.
