Propellors make a big impact on how a miniquad performs & how long a battery lasts.

A prop is described by its diameter & its pitch. A 5040 prop is 5" across with a pitch of 4" which is how far it propels itself through the air per turn. Higher pitch gives more thrust but your motors will pull a lot of amps in the process.

Tri-bladed props are the most common although 2-bladed props still have their place.
