Title: Really jumpy gunsights
Post by: deadfishstink on March 07, 2017, 05:17:23 PM
Returning after several years, and this is one problem I don't remember.    I'm in the training arena, and I'm just working on getting proficient with my guns in a fighter.   

I close slowly on a plane, and even without zooming my gunsight, when I'm within 400 yards, I can't make a steady move to "walk" my rounds into a plane.    Even the slightest motion of the joystick has my sight bouncing all around, to the point the plane pops in and out of the HUD.   At this point I'm just spraying and praying.   

I've working on adjusting dead zones and scaling on joy stick so my actual flight movements are relatively smooth and not jerky, but at this point I have no desire to go to a live arena, as I can't hit crap.

Again, I don't remember this as an issue from years ago, and maybe I'm just brain farting on a setting.

Any help would be appreciated, and sorry if this is an old topic.   I searched jumpy gunsights, jerky gunsights, gunsights moving quickly etc and found nothing of help.

Did you calibrate the joystick?

Start with minimum deadband and damping. I use none on the stick.

The default scaling works well if you want to scale pitch and rudder.

You're flying an unstable gun platform. The flight model will not always let you point where you want to.

What kind of stick are you using? Is it an old one? When you calibrate it (first in windows then in the game) check the "raw" data on the swing out page where you set the dead band and scaling. Is the raw signal from the stick bouncing all over the place WITHOUT you touching it?

If everything with the stick checks out, the biggest thing after that is teaching yourself to calm down. Try flying with just the tips of your fingers on the stick. smooth easy movements are what your after.

for me (heavy handed) I scaled my elevators my scale starts about 1/3 of the way up the scale and the first four are at incremental changes...my second slider is half way half the bar higher than my first slider, third is level with the top of my second, forth is a full sider bar above the third...I also added dampening to just below my first slider....

obviously the slider scale is personal preference so just keep playing around until you have little bounce....I do knoe that even with these settings the P51 for me has a small amount of nose bounce still...

Challanger has a really good 3 part tutorial explaning all about settings and scalling , help me alot with my old stick :)

other solution :
buy a x56 rhino :)

Thanks for the responses.   Will continue to work on it.    I realize a heavy hand is no go as far as flying.   Joystick is Logitech Extreme3Dpro.   Not new, not old either.

Looking at whats happening again, it's more like the nose of my plane jumps suddenly back and forth at the 1st touch of the stick, but then steadies down if I let it come back to it's center and then try again.

I fly with the same Joystick.  I always have a new one in the box ready to go.  One day it's fine and the next, well.......

I get 9 to 12 months out of one and when it starts getting "jumpy", I throw it away and grab a new one.

Sounds like your inadvertently twisting the stick and getting rudder input. Add a bit more dead band to the rudder axis and see if it cleans it up.

Adding dead band on rudder definitely helped.    Thanks Fugative.   Now for some fine tuning....

Thanks for the conversation.  I upped my damping and like the results shooting offline drones.   :joystick:

Regarding nose bounce when trying to saddle up/line up for a shot

A lot of players use CT (combat trim), which actually makes nose bounce much worse when you begin to get slower and possibly dropping notches of flaps

I have always recommended to trim your plane out in level or slightly diving flight, wings level, no other control input..also don't have WEP on either...then you can turn CT on until you have reached anywhere from 275 to 325 IAS (indicated air speed / white needle) then turn off CT

This will allow you to avoid the dreaded nose bounce and allow you to hold a more stable steady stick when saddling up for a shot...also remember the lighter you are on your control input the smoother your flying

Hope this helps. (There is a lot more to it, but that's enough for now)

I'm pretty new around here, but this is something to consider.
I was having a bouncing sight, and unsteady control issue.

Part of my solution, was to arrange a pad for my forearm to rest on.
That maintains my hand in neutral position on the stick, and reduces
the weight of my arm on the base of the grip.

It steadies my touch when making small stick movements, but allows
me to lift my arm to make more drastic movements. I think it also
reduces the wear a tear on the stick gimble, making the stick last longer.

This has also allowed me to decrease my deadband and damping a bit,
making thestick more sensitive overall, while still maintaining reasonable stability.

Another good point.   I do in fact have CT on.   The bounce does get much more pronounced as I try to slow to match the drone without over flying.   

Back to the testing grounds to give this a try as well.   Thanks.

You can trim your fighter for 300tas and above, stay on combat trim until needed, mostly when you dive, then turn off combat trim. You can keep your top speed longer for a chase starting in a dive if you have combat trim off. Combat trim constantly adjusting causes you to loose your top speed and fall back. I surprise players by how long my spit8\16 will stay with them out of a dive or catch up by doing this.

Trimmed for 300 will have you feeling like your nose is heavy when your speed drops under it. If I'm sure my maneuvering will be 200-275 I turn combat trim back on. Two problems with combat trim, if you are trying to precisely pull up under to shoot your nose will pull up above. This will cause nose bouncing while you fight it. And when you push down to get a precise aimpoint, you have to fight the combat trim.

You can see this offline in the drone circle when you get behind and just under a drone and try to hold a steady aimpoint to shoot from underneath while climbing. But, when you are turning low and slow, not having to worry about your nose helps. It's all trade offs.
