"Trim, or not to trim?", that is my question.
« Reply #15 on: November 29, 2002, 05:19:42 PM »
combat trim.........


its is set for level flight at full thrrtle...


when u do anything else it is not ideal setting( divebombing-pulling out ogf hispeed dive-slow turnfitghts etc..)

I rarely use it in dogfights,,cuase its not mapperd on my joystik..I dont have enuff buttons...

But i use it almost everytime on the Dive Bom..becuase i enter

I make my rudder straight..

the dive at stall speed ..and with trim set on Combat it makes you side slip a bit becuase of the P-factor it was trying to make up for when ur engine is full thrttle..Which its not when u are diveboming ..this stops ur side slip aproach and ur rkts fire perfectly straight..instead of side ways ...

Using trim correctly in all styles of fighting will help alot!!!!

I also use it to get out of compression..wheich has savewd me many many times....and also caused nme chasing me to die ..many many times...(hitting ground while chasing me in dive)


Love

I always use manual trim, adds to the game.  In real life you manual trim too, as it makes easy work of a lot of manuvers.

The only time I use the auto-trims is when I'm climbing to cruising altitude and auto-level to trim out at speed.  In combat I use manual trim but just to trim the nose because in the P-38, that's really the only trim you have to adjust.  I never use combat trim because it's not effective in the P-38. There's only a small window where the combat trim is effective but in most combat situations in the P-38, you won't be in that small window.

Lephturn posted an article on his site about auto-trim in Aces High.  It covers all the different trim modes and should clear things up about the advantages/disadvantages of auto and manual trim.

Yes, I use Combat Trim in all the planes I fly.  I've tried using manual trim, it doesn't really seem to give me any 'advantage'.  

Even if the plane is out of trim at low speed, I just use the controls to keep it flying where I want it to fly, doesn't seem to effect much, in my opinion.

Combat trim compensates for the lack of analogue rotary controls. I don't use it when in combat, except when I'm not turning, at which point I'll flick it on and off to get the plane flying straight.

When I'm flying around the sky, I tend to use autolevel and pitch quite alot.

I don't think using Combat Trim as opposed to manual trim or vice versa gives you an advantage, it really does boil down to personal preferences.  
But in some planes, Combat Trim isn't effective and the P-38 is one of those planes.  I usually only trim the nose in vertical maneuvers to get the most out of the P-38's vertical performance but that's it.  When I first started, I used to sometimes trim the nose down in turn fights but with the auto-retracting flaps and the spins they can cause, I rarely do that anymore.

I never use Combat Trim.  I manually adjust trim during combat if needed.  I did try Combat Trim in my beloved Typhoon but it would almost always put me into a flat spin during dogfighting, so I haven't bothered with it since.

Just that they were also lacking on the real WW2 fighters.

ccvi - are you saying that WW2 fighters had no analogue trim controls? I find it hard to believe there were a series of 'notches' or minimum increments.

S!

I use Combat Trim for cruising and manual for fighting.

IMHO
109 needs alot of active rudder trim. IRL 109 didnt have cockpit rudder trim at all and pilot need give constant feet to keep ball at(in?) center.

Trim is needed to keep an a/c flying straight under the influence of aerodynamic factors.  Torque and propwash affects yaw and roll axis' which means rudder trim and aileron trim is needed to maintain straight flight.  Lift of the wing varies with velocity and air density or various airframe configurations (e.g. flaps) thus elevator trim needed to compensate for the pitch axis to maintain straight flight.

In AH since 1.04 there is no aerodynamic advantage in maneuver for using manual trim over combat-trim.  Personal feel is another matter (e.g. trimming so that a/c is in straight flight when the stick is centered with flaps deployed etc.).

I always use combat trim.  I use manual trim for damage, gentle course corrections, or helping to get out of compression.

Andy Bush at SimHQ has written a nice article on trim with various flight sims in mind:

I myself find using manual trim is necessary.  To be able to get a turn on the P51 i adjust the trim accordingly, but do to its limitations Manual Trim is only usable for about 60% of the time for me.  I use elevators more than i use Ailerons on Manual Trim, since it helps me with the barrels.

It may seem a little difficult once you start trimming, but once you get it down it will become much easier.

I use auto climb and level quite a bit. Helps when grabbin a beer :D

But in a fight I use manual trim, trimming for the dive, for the merge, lead turn etc.

Reprogramed them to the up and down arrow keys, easy to find.

If I could map the trim controls as an analog device to the rotary wheels on my Cougar's throttle I'd use trim pretty much exclusively.

It might even be somewhat intuitive and natural that way.

As it is, manual trim is a bastardized gamey thing that bears no practical resemblance to real trimming.
