but thats my whole point:

modern fighters use joysticks of short stick

old fighters used long sticks

do you realize the lenght of the stick is what determines run or sensitivity?

You've posted an image of an F-16-stick. Which moves about 1/4th of an inch all in all. That movement is NOT, in ANY way, what defines the amount of controlsurface-deflection on the Viper, as it's flight-contro-system is set up so that it's how much FORCE you use that is used to measure the deflection-angle.

Comparing that to a Spitfire, which you have done here, is idiotic, even for you.

You can add the fact that most modern-day fighterjets use a Fly-by-wire system, i.e. there's no moving, mechanical linkage between the stick and the control-surfaces like you have on for example a Spitfire. It doesn't compare at all, in any way.

haha so moving one cm = 100 kg onn the elevator

myself on the stall limit paragliding measure by grams while normally by 20 kg so youre gullible if you belive that

You're not getting it: The stick in an F16 is not connected mechanically to the actuators that drive the control-surfaces as you would find for example in the F4 Phantom. The stick in an F16 only moves 1/4th of an inch in order to give the stick SOME deadzone, which was a wish from the first pilots that flew the bird since they found that a completely non-moving stick (which was what the very first production-birds actually had) was unnatural to them.

The stick in an F16 senses how much force you put on the stick, sends that input to the flight-control-computers, who then do the math to make the aircraft do what you want it to do, as long as you don't exceed the maximum G-load the aircraft can take at that speed.

So again: Posting an image of an F16-stick in this discussion is completely and utterly useless, since it's not mechanically linked directly to the control-surface actuators as you have in a Spitfire (Wire-and-pulley system) or an F4 Phantom (hydraulic system).

youre confusing the thing by throwing random facts

the fact:

modern fighters have short sticks

old fighters had long sticks

modern fighters have short run

old fighters had long run

modern fighters have high sensitivity

old fighters had low sensitivity


show me a picture of a new fighter with a long stick that is with low sensitivity

man i grant you in the future racers will go with insane high sensitivity in their wheels is a matter of a pioneer doing it and washing the floor with the rest

Hahahaha, not one, not one thing you just said is correct

F-16 doesn't have short stick travel. It has 0 stick travel.
But then pilots started complaining that they have trouble orienting and realising where the stick acctually is. Then the designers introduced 1/4 inch or 6mm stick travel. And that is "empty travel" not connected to the control surfaces in any way.
Maximun noseup and nosedown pitch commands are genrated by 25 and 16 pounds of input, respectively. Roll commands are generated by a maximum of 17 pounds in cruise gains and by 12 pounds in takeoff and landing gains.

But that is still only one aircraft, and it was problematic.

Wanna talk f-14, f-15, 1-104, f-111, f-117 and literally hundreds and hundreds of airplanes before and after that from all the countries around the world that have conventional sticks, with 20-30+ cm of travel. Just like the WWII fighters.

Even if your statement would be correct, older fighter can still out-turn any modern one.

Have you actually checked any of your statements before stating them??

Oh, and by the way, I'm an inventor with a engineering degree. A professional one, making a living of it. So I'm all for open mindedness and thinking out of the box.

ive seen many FIGHTERS in movies and all used short sticks

your confusing run with force feedback

f16 has a stick with extreme short run AND A STRONG FORCE FEED BACK

sensitivity is related with run not feed back

so the f16 and many other stick SHORT RUN give away my point of the high sensitivity advantage

the only sensible point ive seen so far except childish bias is that high sensitivity in racing is limited for safety reasons
