Title: Manual Trimming and Combat Trim
Post by: curry1 on April 06, 2012, 12:33:01 PM
So I was was doing some 1v1s with shiv last night and he started talking about setting the trim nose down so when you pop flaps it doesn't cause the plane to bounce up as much.  Since I am cheap I have a Logitech 3D Pro and no analog slider to control my elevator trim.  Is there a way with keystroke to set my trim so when I turn of combat trim it will automatically go to a default setting?  Or am I hosed with no analog slider and have manually trim the elevator down with the "i" key?


So here is a cat with a piece of bacon taped to it for your viewing pleasure.

I think you're SOL, but that picture is funny.  :lol

No there is only the key stroke. You could use your sticks software to create a macro to hit the trim switch the same number of times on a single hit.

Only problem with that is when you turn combat trim off there is no way of knowing where the elevator is trimmed at at that specific moment.  So hitting a set amount of times will not work.

It will be close enough as you'll switch at about the same times and speed in your fights so the combat trim will have you trimed at about the same trim al the time.

Just push your stick forward. Flaps will change your effective AOA regardless of your trim setting and flaps generally extend faster than trim changes. Personally I like the nose coming up, that's usually what I want when I extend flaps.

Uhh no that is definitely not what I want when I am in a dogfight trying to shoot.  The last thing I want is my nose bobbing up and down while aiming and shooting.  Most every good pilot uses the trim to get more out of their aircraft.

Thanks for the tip. Why are you extending flaps when you shoot?

You can trim by keystrokes k=up, i=down, j=left and l=right. The x key along with its combinations will reset all trimming.

On the odd occassion I want to manually adjust trims to avoid applying stick movement. So I use the period key. While you are flying with controls moved a little to suit a certain attitude, pressing the period key will move the trims to trim out to where you were holding the stick. It is important that you are not moving the stick around at the time.

Typically when on approach and I am in a shallow dive to the runway I use the period to trim out the forward stick I would otherwise have to hold. It trims all controls so if you also have aileron in to counter reduced torque that gets trimmed to

Good tip Blagard. I think most players don't even know about trim set. It doesn't stay set with analog trim but when you hold the period key it will move the trim indicators and show you what the analog trim position needs to be to get the same result.

You can trim for a dive with auto-angle (shift x) and it will also trim aileron as well as elevator but trim set will let you set a descending, level, or climbing turn. It would be handy if jumping to the gunner position didn't turn trim set off.

Typically because I am in a dogfight and trying to out turn the other fighter.

If you need to increase your turn to gain angles for a shot then you want your nose pitching up.

True.


We are getting way off topic here can we please go back to the OP and try to answer my question?

When you pop flaps push the stick forward to prevent the nose coming up.

If you tend to have problems with nose bounce see me in the TA. In my experience nose bounce problems are usually too much damping and deadband.

FLS, I think what we're talking about here is a rolling scissor type situation, where combat trim will keep pulling your nose up even when you don't want it to.

Shutting off combat trim and manually trimming the elevator down will fix that. And if you have a slider mapped to elevator trim you can preset it so you just shut off combat trim and have the flaps go to neutral or nose heavy or wherever you have the slider at.

Curry was asking if there was any way to preset without a slider, in order to switch back and forth between the two with having to hit the i key to manually trim the elevator down each time.

But yeah, SOL as has been pointed out. I thought maybe trim set would do it, but it seems trim set is reset every time you go back to combat trim, I was trying it offline. So it's i key or a button or nothing.

Thanks Shiv. The post said pop flaps but I had thought it made more sense as a combat trim vs manual trim question. I would suggest using auto trim on angle entering the fight to set the elevator trim and just leave it there. That will trim you nose down for the slower speeds after you start turning.

Yeah that's what I have determined to be the best alternative as you are still relatively fast entering the fight.  Then I make adjustments using the I key if necessary.  At least I am doing the best thing possible with my materials.  Thanks again.

Well, I fly the F4U series alot......... and I (before actually engaging, but roight before ) will nose low to gain speed/seperation/and looking for the 325to 350 window in the hog IAS speed )  before turning off combat trim..........and I leave it there through out my entire fight........ which gives me a situation to where I have to have a slight to constant pull on the joystick...... looking for a shot........ ro bring guns for a solution/target

I do not have to worry about nose bounce, in this instance...... because my trim is set for a flight being stright with no control input nor with any wep turned on at a speed from 325 IAS to 350 IAS depending on the F4U series/type plane I am in.......

I do the same things in each individual plane type.............. depending on what their max level cruise speed  ( IAS & TAS depending on altitude ) is recorded at.....

my gunnery is horrible, but just imagine what it would be if I had to deal with "nose bounce".............. in which case it is not necessarily linked to speed but more so that the flaps do not take in to account the speed of the plane, they are always trimming for level flight based on the speed of the aircraft...... I do not rely on combat trim, when I am engaged with 1 or more planes / plane ypes..........

just a different view...

Yep I agree.

I fly combat trim most of the time though a quick dose of manual trim may bring your foe into scope fast or help you escape is grasp.

Post by: diaster on April 11, 2012, 09:47:05 PM
That's the weirdest thing about this game. The purpose of trim is to relieve stick forces at given configuration and aoa so you do not have to maintain pressure and when consequently initiating a directional change you do not have to first overcome current resistance/force, i.e. flying around with stick help in your lap then u have to pull even more. In this game it seems to help you turn even faster which puts you in a bad trim position when you come out of the change in direction. In RL you would roll off the trim as you ease the stick forward to counter the forces on it/you

So in game, I use my hat switch to apply and remove trim as needed as in RL, almost as a mini stick, pop flaps push forward on the hat i.e. pilot wound on approach, I trim long glide slope at 125 indicated and apply throttle to adjust touchdown point, if i pass out it lands itself anyway), in a fight the hat trim down helps the nose to come around smoother, but it doesn't reallly get pointed in the right direction and i end up pulling more stick unconsciously. really obvious in the f4... but then  i need a lot of practice in it

In the game you also trim the forces off the stick. Instead of trimming the control surface pressure off the stick you trim the spring pressure off and the stick is centered when you're trimmed.

Trim does not increase the control input and help you turn faster. If it seems that way it's an illusion.

Then why when I fly a P-38 or K-4 I can use the vertical trim to get out of a dive I never would with just normal control input?

It's not that trim 'increases control input', but rather it allows the little cartoon dude inside the cockpit who is modeled to pull whatever amount of force he can pull (100 lbs?) to overcome the force on the other end of the stick and pull out of the dive you're in.

I fly most of the time with combat trim on.  If I find myself in a stall fight duel where I'm trying to force an overshoot, when my IAS gets down around 150 I turn off CT and leave it off until I start picking up speed again.  It seems to me I can ride the stall horn better with CT off than with it on.

I agree on that I can definitely turn and keep control better at low speeds with my CT off.

Manual trim for corner speed before the fight. Never use combat trim.

Yeah normally I turn off CT on the initial merge and I leave it for the remainder of the fight if the situation allows.

Personal preference. For me I toggle it on to get a ballpark balanced setting at a given speed and then turn it back off again. I prefer a slight nose down trim. In the P-38 combat trim tends to want to force the nose up more than I'd like at slower speeds and I find myself fighting the stick to keep the nose low. I don't like it. I have all trim commands mapped to my stick which comes in handy in situations like when I lose that extra engine.  ;)
