JoyStick Problem

[gloomygod]

Hi all. I got a rare control problem with this game. Maybe i'm a novice and it's so simple, but i can't reach a solution.

 

the problem is: when i'm in a flight, "SOMETIMES" not always the plane starts to move its nose up or down, and i can't put it straight, on level. The only way i can level the plane, is pushing 'H'(auto-level) and then turn it off. The plane remains on level, and as soon as i move the stick for a minute, the plane gets again crazy, climbing or descending .

 

I put the stick on the 0 level, quit my hand, and theplane starts climbing again!!!!

 

I suposed it was a joystick problem, so i bought a new one, with the same results.

 

Of course, in the windows control panel, the joystick seems perfectly calibrated, and inside the game in the "test" screen it is right on the center.

 

Anyone has the same issue???? There's no way i can fly !!!

 

The new Joystick is a logitech Extreme3D Pro

It sounds like you are not trimming the aircraft.

 

Also, after using an autopilot mode (like auto-level), clear the trim with the Alt T key.

I'm trying right now with the keyboard only, and still can't level the aircraft. I tried to clear the trim settings too.

 

I'm doing that with lomac 1.02, when you enter the game and press Fly button on the Mig-29. Once you press the S key for start, the plane starts in a position like 45 degree nosing up.

 

In the moment i tunr off the Auto-level, the planes stays on level.

 

i press the up arrow key twice to push down the nose, and when i try to recover the level, i can't control the aircraft...

 

Am i missing somthing??? I can't be so hard to control the plane!

You need to trim the aircraft.

 

 

Not cancel the trim - trim the aircraft (which I think is mapped to Ctrl-T, btw). As you go faster, it wants to pitch up - that's the way it works. Not a bug.

 

 

The aircraft stays level after turning off the height hold key because the autopilot trimmed the aircraft to that height and speed. Accelerate beyond that speed, and the aircraft will pitch up more.

 

You just have to live with it - sorry.

ok, assuming i'm a novice pilot, could anyone give in a few lines an accelerated lesson of how the trim works???

 

I have found the keys for trimming left, right, up, and down, but i don'w know wich way to trim the aircraft to level it . I suppose if the plane tries to climb i wil have to trim it down, right?

 

And one thing more. In the real models, what does exactly the trimming function?? What moves the trimming to equilibrate the plane?

I find it in top secret document (1.1_Readme)

==================================

When setting the joystick response pitch curve for aircraft with Advanced Flight Model (Su-25 and Su-25T), it is recommended that you remove any joystick insensitivity near the neutral / centering area (the so-called “dead zone”). You should also have a linear response curve;

 

meaning that the joystick pitch setting curve should be a straight line from corner to corner of the response field. This is recommended because any nonlinearity will distort the correct balancing of the aircraft. This AFM balancing consists of angle of attack, G-loading, and control stick longitudinal diversion. A dead zone would create a “flat” response area (local control insensitivity zone) when balancing the dependencies in the mid-angle of attack range (5 - 10°). This would make angle of attack and G-loading control difficult.

For aircraft with AFM, it is also recommended that you reduce nonlinearity of the yaw response curve. This is because the nose wheel turning mechanism of Su-25 and Su-25T possesses a differential mechanism that nonlinearly turns the nose wheel according to the amount of pedal deflection. Hence, the yaw response curve nonlinearity will cause a significant increase of nose wheel turning angle. Such nonlinearity when giving rudder inputs will make it difficult to hold the aircraft on the runway during taxi, take offs and landings.

=========================================================

You have to make this setup in game properties and check how it works.

Correct. You trim opposite the direction of the unwanted movement.

 

And one thing more. In the real models, what does exactly the trimming function?? What moves the trimming to equilibrate the plane?

In the real aircraft, trimming just moves the motors controlling the flight stick so that it is offset in a certain direction; you can see this in the posted pictures. Basically, trim allows you to deflect the control surfaces the proper amount without constantly exerting force on the stick.

 

Trim can be confusing to think about when flying sims, because if you trim a real aircraft, the control stick remains displaced, you just no longer need to exert force. When you use a computer joystick, though, it remains centered regardless of your trim settings. That is why it is important to pay attention to the neutral trim lights in the aircraft cockpits, and to note the displacement of the in-game control stick.

 

Also note that in the Su-25 and -25T, pressing CTRL+t (reset trim) has no effect. The most effective way of regaining control in those aircraft is to activate the EMERGENCY LEVELING autopilot. Once you have stabilized, you can then DEACTIVATE the autopilot (without moving your joystick) and you will be trimmed for level flight at that speed. If you are trimmed for a certain speed, increasing speed will cause your nose to pitch up, and decreasing will cause your nose to pitch down.

This might help some;

 

I had really bad problems with my joystick in Lomac. The plane would be over sensitive to even the slightest movements. For example, coming in to land i would be gradually pulling up, but the plane would jerk wildly up, then when i went to correct, it would dive down a lot. So very frustrating, A2A gunz was imposible so was A2G guns and rockets.

But finally i got sorted. What i did was make the response curve for pitch and roll, very curvy. So it would take 60+% deflection on the stick to get some reasonable movement, whilst the <60% was strictly for slight movements. And it worked, no more spilt coffee on my privates during landing :cool:
