Well, actually there are some tips in selecting the most suitable props (yes, there's no definitely perfect props!!) for your aircrafts.
First you need to know, what's your preferred effect? Steady, agile, or crazy flight?
Thrust of the prop depends on: 1) size; 2) shape/surface area; 3) number of blades; 4) materials
Also take into account the diagonal motors distance, motor power, etc. when choosing.
So if you want higher power, you can use longer props like 6-inch ones, but the agility would be sacrificed. For example, to install an FPV camera on, you need the power. How the prop looks like will also determine its thrust - in the shape of bull nose (BN), hybrid BN (HBN), and pointy nose. Thrust: HBN>BN>pointy nose. Also the number of blades can affect the power: 2-blade, 3-blade, 4-blade, etc.; the more blades, the higher power.
After knowing these determinants, you may still be confused. So let the facts speak for themselves. I'll show you how to use a scale to test the thrust of props.
