Presets for trims - yes please!

I am developing it for IL-2 already. It's not very complicated (not for you SoW guys at least, for me it's worse using devicelink etc).

I made the following functions that are logical. I imagine SoW should use the same functions (what else is there?)

Set range of trim possible (to avoid excessive sensitivity and extreme trim we never need anyway).

Set trim off-set from center (since many aircraft only need to be trimmed to one side from center, it's a waste to always have the other side included. With this users can make use of the whole range of their trim axis, not just half. It also permits even lower range used, further making trim less sensitive and easier to be accurate).

Only one profile so far. To add in user customizable trims for different planes.. work work work.

So probably I'm right with this at least for a sim.

Heh, yeah. It's the way to go.

Just consider that if using off-center function, there must be a way for the users to know that their trim is centered (they can no longer rely on physically watching their real controller). I tried without and it's very difficult to know (watch the rudder pedals move? heh).

On the G940 I am made a throttle button light shine yellow if a trim is centered, just like the Pe-2 aircraft does. Will add a sound effect too I think. I don't know what you can come up with.

I will think about it. Should be useful for all doesn't matter which one of devices they are using.

Currently we are using customizable and saved separate profiles for each aircraft. They can be selected and loaded by user for using with his beloved aircaft. The is is also tuned curves for Joy.

How many of the aircraft in SoW have visible functional trims in the cockpit? Real pilots could probably see this before take off and in flight. Then our off-set makes no difference and causes no problems (it does in IL-2, because IL-2 often does not have these cockpit details). When airborne we can just see or feel if we need to trim so center doesn't even matter there.

Optional helper: Small, transparent pop-up window (at any time) showing the position of our flight controls. Useful for more than just checking trim positions.

Profiles: Force feedback tweaks, and the 'force sensing joystick' tweaks (I posted topic a week ago suggesting how it should work) could be useful for each aircraft. Our force feedback joystick motors are not strong. Also some hardware doesn't work that well with too much or little forces involved. Flying a heavy plane can make it function badly while a normal one is ok. Profile tweak can fix so we don't have to alt-tab each time.

Force feedback for SoW. Much better than IL-2? There's a big spring deadzone in IL-2 from the old FFB drivers, and the center of forces is always in the same place.

Trims and joystick center - This is a big topic for controllers. IL-2 trims control surface deflection directly, making it possible for us to let a spring joystick rest in at center yet still fly straight. Can even fly aircraft completely without having a joystick connected.

In real aircraft, trims only changes the forces on the stick, allowing the pilot to push the stick to a new position (required for flying straight) and keep it there without force. With the arrival of the G940 (and other existing no-absolute centering joysticks - Tarmac Aces in France make some amazing things) and probaby more to come, we could allow trims to work like real trims; change the force feedback, not the control surface deflection (they still permit the control column in game to move further during compressability though, as this cannot be simulated purely through a consumer type joystick).

If using curves with a sharp center point on the joystick it can become slightly less intuitive when the stick is off-set. If trimmed forward because of high speed (dive etc), moving the stick can give a different response to input. But (edit) we never need to move the stick far for trimming anyway (except in exterme situations, but then we are not gunning, or the plane simply cannot move much anyway due to compressability), and we don't have to use a 100% spiked curve for the joysticks. A bit flatter, larger center of the curve and it won't be noticed. The offset in our hand also makes it obvious the stick is not centered.

From this point(above) will read-answer tomorrow.

I´m at work and can´t search properly for a good source to confirm what i´m stating, but i think you are mistaken. It might be true what you say with aircrafts where the stick does not have direct physical connection to the control surface, but have connection to an artificial force system. But on WW2 aircraft, and modern light airplanes, where the stick have´s direct physical connection with the control surface, using the trim does imply moving the control surface, and by doing this, you are releived of the effort of continously have to apply force over the stick.
The trim could work by moving the control surface directly, or moving a tab that moves corespondly the control surface, but triming the aircraft does imply that the control suface is moved.

MikkOwl. Your ideas are good, expecially the ones with the sticks. But indicators on screen..well..maybe for testing etc. In real aircraft you can see from the trim wheel or and indicator near it the position of your trim. This in most planes. And with SoW having very detailed cockpits, from we have seen so far, this pose no problem to actually look at your trim wheel for the indication. Spitfire has this trim position Up/down in the dashboard etc.

Well that settles it. Oleg has no excuse for not permitting off-set adjustment of trims. The problem for him to tackle is instead: "are my SoW models awesome enough for the task? ". And, it is optional after all. If anyone doesn't want to use it they don't have to. But anyone can benefit a lot from it with trimming, as it makes our poor little devices so much less twitchy and crazy sensitive with trimming in game. And if we reduced range to make it less twitchy, we can even get increased range again by using off-set trims (positioning the range at the 'right part of the trim' makes sure no part of axis is wasted).

Well yes, I know about how trim tabs work, and that only describes the mechanism behind the result: as far as the control surface and stick goes, only the forces acting on the control column changes. If stick is kept centered and trim tabs are moved, nothing at all happens, the control surface does not move (only that tiny tab).

I don't know how non-trim tab aircraft function, but I am not really aware of any WW2 combat aircraft having that sort of trim. If you know of any I would be happy to read up on them.

If they move the whole surface directly, completely independant on the control column, then yes, they should be like now (just far smaller range of movement). But I'm fairly sure they are by far the exception, and that nearly all aircraft are using trim tabs.

The features of this is freezed already. Open was only about trims.

Frozen, ok But I was asking: force feedback taking any step forward (significantly) compared to IL-2? And then I made a wishlist request on how it could/should behave.
