There's two things you can change in these bases:Do the cosmo cams make Elite better? I assume they are “soft return”, so the stick doesn’t spring back to the centre as soon as you let it go?
- the force of the springs (low and medium are included, hard has to be bought as extra)
- the shape of "force curve", that's the cams
The regular (default) flight sim cams will show an increase in force the further you pull the stick from the neutral position. The CosmoSim cams have a flat profile, the resetting force will be the same pretty much all over the range - but the stick will always pull back into the neutral position. The "weak indent" has a weak lock to the center position, the "no indent" is supposed to have no lock to the center position - these may be better for full FAOff, but neither do I have these cams nor am I usually flying FAOff.
So, the stick will always pull to the center position (unless you remove the springs completely, I'd guess), but the choice of spring and cams will influence how it will pull back.
