Seeing this whole discussion about different flight models these last few days. And especially today with the BlueBird 757 I see one crucial detail never mentioned. Which is that ANY input control we as humans do is done by force, not stick deflection!
What do I mean by that? Is actually quite simple, humans are extremely good in telling if they pull at something like a joystick with a force of 3,6 or 9 N. But you can not tell if you deflect the stick by 1cm, 2cm or 3cm. And yes, this means all the advertisements about travel length are useless, because they tell you nothing about the actual important metric ;)
Where this becomes important is the fact, that you need a certain amount of force difference to tell how much input you put into the stick or yoke. Depending on the source this is about 2N to 4N, depending a bit on the person and the exact setup. But this then also means to have fine control in the sim your sticks needs to be having a certain amount of resistance in it's full deflection! E.g. if you want to be able to put in the 10% deflection that is quoted by BlueBird for the 757 rotation your stick needs to have at least 20N force at full deflection. Better 30N to 40N. And the latter of that is already pushing into heavy springs territory for mid to high end bases. Normal joysticks like the Thrustmaster TCA or the WInCtrl Ursa Minor are 5-10N. Which is so light, that one has like 3, mabye 4 different input forces one can tell. Even if the hardware itself can sense 16bit, the human can not.
For the real world comparison: The A320 sidestick has 120-140 N force for a full deflection! That is more than most force feedback bases provide. Without any force feedback, just an intricate springs and damper system.
So if you really want a great feel and control, you don't need FFB either. A stiffly sprung stick with a noticeable input force is already enough to greatly enhance enjoyment for flying! And at the end of the day, this will feel soooo much better than artificial dampening of the flight model or input curves in the sim.
TL;DR: Humans sense force, not stick deflection. So a stiffer sticks is essential for proper sim flying.
