There is a world of difference between props/power on an airplane and a MultiRotor that has every aspect controlled by the Flight Controller (FC). With other no FC aircraft you can mix & match parts to get the results you desire (more acceleration, higher top speed, longer battery life) and we've done it for years with our planes and helicopters. When I flew "planks" I would show up at the field with one box full of props for a single plane.
Literally a couple of dozen different brands, materials, lengths, and pitches. Fly > Chang Prop > Fly > Change Prop > Fly > Change Prop and then flyyyyyyyyyyyy.
With an aircraft that "flies" solely via the propulsion system (MultiRotor and Helicopters) AND that has a FC integrated into it you have a whole other system that isn't "Tinker Friendly" except from a programming level.
The FC is programmed for a specific horizontal and vertical speed. It will do everything within it's programming to maintain flight within those parameters. So you won't see any significant performance gains like you will on a Helicopter or Airplane.
Also one lesson I learned the hard (expensive way) is that when yo strengthen a point that is designed "Weak" you transfer the energy deeper into the aircraft. Instead of bending a soft prop (or even chipping it) you now have a rigid prop and that energy will be transferred to the next weakest point. That's usually either the most difficult part in the world to find or the most expensive part to replace LOL.
I can assure you that the design and "softness" of the DJI props is not by mistake. They spend a lot of $$ on R&D to make sure the props are an efficient and reliable part of the propulsion "system".
