f16 trim issue

[Viciam1]

Hey guys, is there a way to reset the trim on the f16 in dcs to its neutral position? Once I've changed it even slightly I can never get it to go back to 0

Thanks in advance

By your left hip are the manual controls and deviation needles

How about getting a finer trim ability? This thing simply won’t trim out.

the trim hat doesn't work correctly right now, but either way it is super sensitive in the roll axis, so not much you can do about it really. Use the trim wheels located on the trim panel on the left console for finer trim. Safe flights!

I find a click of trim in then click it back out seems to work for straight and level flight

Yup, the trim hat isn't working correctly which is kind of sad. The only advice one can give to the OP is to go and practice using the those trim wheels. It is pretty inconvenient for sure but you will get a certain finesse after you practiced a little, I promise. Really nothing else you can do about it at the moment, I guess.

even with the trim hat working correctly it won't be much of use for very precise trimming.

True. But as you know you can trim out the jet reasonably well and the OP seems to have problems even with the basics of doing that. So, all I'm saying is that the OP needs to put in a little more effort and practice a little more with the wheels to get a feeling for the jet and what works best for him. Training is key to success.

totally agree on everything mentioned ^

What exactly isn't working correctly? On my side it seems to do exactly what I would expect from a trim hat: trimming in 4 directions.

Yes, it does trim in 4 directions, however the way it trims is incorrect. In game the trim hat trims the aircraft in clicks, meaning that you will often times see yourself in the exact same trim setting. Chances are that if you have an asymmetric loadout the aircraft will never be able to have a good trim. IRL this isn't how it works. IRL, trim is purely a product of time the hat has been held. It's very accurate, no clicks. Chances are you can't get the exact same trim setting two times in a flight. This is why trim is incorrect currently in DCS.

Hmm, interesting. I've never noticed, that it works in clicks in DCS. In game, the longer I keep the trim hat pressed in one direct, the more it trims. If I just want to make a very small adjusment I very briefly flick the trim hat in the respective direction to achieve exactly that: a very small trim adjustment.

I am having this issue as well. Previously I flew the F-14 and the trim always worked to level the aircraft in any configuration. On the F-16 it seems to work in discrete 'steps', or at least that's what it feels like...for most of the time after firing at least one weapon, I am never able to get a setting that levels the aircraft and it is always rolling slowly.

 

Another issue that I have noticed is that when I use the slew on the maverick with the tiny joystick on the warthog throttle, even though it is an axis joystick it seems to move at one speed. I tried limiting the saturation in the axis tune but I can't seem to slow it down. It makes it really hard to lock on targets even when ground stabilized, at least for me.

If you're just rough trimming you will not notice any problems with the trim system at all, but when you want really precise trim the clicks are clearly noticeable. Let's say you fly with a symmetrical loadout, no TGP. You can easily get the aircraft to fly dead straight, if you mess up the trim again it's not a big deal to get it back to perfect again. While, if you slap a TGP on the aircraft, you will never be able to find that perfect trim. You're either rolling slight right or slightly left, and always the same amount. IRL there is no such thing as perfect trim, you're always rolling to one side or the other because the trim isn't in clicks, it's smooth. You can reduce the roll rate to almost none, but you will never get it perfect like you do if you fly in DCS with a symmetrical loadout. This should be changed, but I think ED has confused what their SMEs are saying. Most pilots say that the trim panel should be used for precise trimming and the trim switch is only rough trim, but this doesn't mean that the trim switch should work in clicks. IRL it's super smooth, almost impossible to hit the same trim setting twice. I hope that makes some sense. Anyway, not a big deal, but it's noticeable if you're looking for it. Safe flights!

Do you guys use trim during air refueling in f-16?

Not at all, only stick and throttle

Never ever, except for roll trim on asymmetric loadouts. A good practice is placing your gun cross on the end of the boom and keep it there before pushing forward. Throttle is most important. 

It takes tons of practice, especially on the throttle on which you need to think ahead of time due to the engine spoolup time. It is quite easy to get into pilot induced oscillations. If that happens, it will is easy to solve in the viper: push a little into a safe direction and let go of the stick. FLCS will sort it out.

Then go back, stabilize the gun cross on the boom and gently push forward again.

I've found that if I do two mouse wheel clicks up on the trim wheel during start-up with a TGP mounted I have no trim issues whatsoever during flight. Once ordinance is released that is another matter.

 

I found counting the clicks of the mouse wheel and then removing that input helps more than using the trim hat switch most of the time after releasing ords. I agree, It's pretty tough to get trimmed out using the hat switches, I hope it gets fixed eventually but other things should come first.

This is a pretty smart trick must say, although it is mostly a sim gimmick. IRL you trim every once in a while to keep the aircraft straight. You never take off and land again without touching trim, that's not how real aircraft work. Maybe one day ED will have the flight model so dialled we will actually notice these things.

I find rudder trim works better for TGP load outs and aileron trip for pylon load asymmetry. Not sure whether this is normal for real-world operations.

IRL your trim is always messed up for every axis because of the trim checks you do on startup. For that reason you need to trim the aircraft once in flight. As long as you don't have any major asymmetry (TGP does not contribute much) you will not required future trimming of the aircraft. You trim for yaw using the slip indicator (the ball located on the ADI). With asymmetric loadouts you might require re-trimming when changing airspeed.

Yea, I completely agree, IRL your constantly using the trim wheel, I'm studying or my PPL and trim is my best friend. It would be cool if ED can get that level of realisms someday, this trick does get me around the hat switch not being sensitive enough which tends to drive me nuts. I don't trim for asymmetric loads very often so I don't get into that dance of hat left, right, left, right, etc, I'll even AAF most of the time without trimming.

You just need to use DCS' poor control configuration against itself - cockpit rotary dials/knobs by default have stupidly small 'increments' of travel per click/input - so map a hat or something to the roll trim dial on the trim panel at your left-aft side panel. That way one click of that trim instead of the trim hat on your stick will give you much finer trim control.

 

....and just continue having to rotate your rotary encoder mapped to cockpit lighting/HUD brightness etc. a billion times to actually adjust that stuff lol.

Is this something achieved in a HOTAS software and not a controls binding within the game I'm guessing?

 

EDIT:  Nevermind, found the binding for it in DCS.  Wow this is life-changing!  Sooooo much smoother to trim.  Now just gotta figure out how to travel down the runway in a straight line lol.
