Drone props allow your quad to actually take flight. This means that keeping good props on hand is the best way to get more airtime. Drone propellers have a lot of different properties to adjust how they make you fly. The pitch will make the blades have a sharper angle, which will add more thrust, but also drain more battery. The Blade length has a similar effect. Blade shape and width can also affect these things, but it is much harder to see the differences without flying them yourselves. It is best to buy 5 sets of props if trying out a new style so that you can fully get their experience and see if you like them.
