hey guys, this is not related to VPforce but given our mutual passion for FFB maybe this is the place to ask - i am trying to get ffb to work on my msffb2 base with IL2 1946
as it stands i only have a spring centering force and nothing else
i suspect that my use of vjoy is what is causing the issue, but cant confirm this yet - any ideas?
you'd be better off asking in the HOTAS discord
6:1, 12t drive but final is smooth and is just the arc of the belt paths vs a full round to reduce height. Haven't cut metal yet but in Fusion my total height will be around 225mm (bottom to top of enclosure), 177x177 footprint. With no extension or grip, pitch length is 125mm and roll 60mm
sorry for the late ping. Not sure how good is the FFB support part in those DCS modules though, but for the behavior of the real ones: F-16 probably won't be benefited from a FFB base since it's supposed to be a force sensing stick; for the 18, other than what others had mentioned, one benefit from a FFB base is, you can set the deflection & stick force of the pitch axis asymmetrically like the real one(i.e. weaker max force & deflection for pushing than pulling), which is impossible for most if not every traditional spring joystick. And there is the beep trim(moving the physical center position by pushing the trim hat) for the "backup" control mode as well, iirc. BTW this are also for the pre-full-FBW 4th gens such as the F-14 and F-15. Of course as mentioned, you can fine tune the artificial spring, damper, friction effect to better match the properties of the real one, where as in a spring base, the capability of adjustment is restrained by the choice/physical properties of the limited springs, cams, dampers variants etc. Essentially you can treat it like a "reconfigurable/programmable" spring stick base for FBW aircraft. And with this base in hand, if you want to fly another type of aircraft, you don't have to disassemble the base, swapping the springs what not; you can just "change the profile" and it's done.
BTW, unlike the Boeing FBW found on the 777, the stick force/artificial feeling in the 18, 15, (14 perhaps?), and Airbus is provided solely by the spring (and dampers of course), no servo motors whatsoever involved. After the breakout force, "The feel
spring assemblies provide a linear stick force versus stick displacement gradient in each axis"(quote from the 18E/F manual), no artificial FFB involved. The servo motor, if exists, is only for moving the center according to the trim setting. My understanding is, the FLCS changes the "curve" to provide feedback, ex. you need to deflect the stick more to achieve a same maneuver in different conditions.
Thank you for the incredible answer, actually even forgot I asked about it but now it seems I might have to save up a bit and get one, especially the not switching springs part seem very useful if you fly both fixed and rotary wings
I've been wondering how hard it would be to convert a normal set of rudders to FFB using the kit motors
it's only a single axis so part of me thinks it shouldn't be too hard if you can find a good attachment point for the force feedback mechanism
my TPRs rotate on an axis already so I'm wondering if I could add a belt drive to the point of rotation
mount one of the motors on the top (the red square) and attach a drive gear to the fulcrum point of the arm that links them (the red circle)
oh and I didn't realize that there was some typo about the F-16 part and let me correct it: "F-16 probably won't be benefited from a FFB base since it's supposed to be a force sensing stick".
Also per the report of the Rhino owner earlier, it seems the max stick force feels stronger than (or at least technically on par with) the highest spring setting of the VKB gunfighter, so that's a pro too. And if Walmis decide to make a more powerful version of Rhino utilizing those bigger motors(the current motors are the weakest in his arsenal ), it's gonna be even better.
And if you fly Helo and you want the ultimate realism, FFB it's one of the only way to go. Those dry clutcher are just makeshifts, unless what you fly is those basic helos such as R22 which doesn't have centering springs.
Seems really interesting to use for modern Fly-by-wire planes, would also be cool if you could sense which aircraft is being flown and switch profile settings from that, so you could get spring in plane and no spring in helicopter, but also limit movement based on aircraft and other parameters to get it to feel like the real deal, no matter which aircraft it is
yeah it's quite versatile. (if yrs or decades later the force sensing sensors could be added, it can even simulate F-16, or even better, the F-35, which is a hybrid of force sensing and force feedback😂 ) And actually bigger helo usually has springs as well. Here is another way to achieve the simulation other than using FFB: https://youtu.be/QHpYIi_QhHU

oooo, interesting design
it's in principle similar to what the real helo uses. But not as versatile as a FFB base
Yeah, might be an interesting DIY project for next summer 😁
Did he install hall sensor or something that I missed?
I don't see how he's transmitting position?
the stick knows where it is at all times, it knows this because it knows where it isn't
