Ok I keep hearing about setting trim to get "hands off" control. http://ubbxforums.ubi.com/infopop/emoticons/icon_confused.gif Does someone have some specific settings fo me to use and the best way to use them. I prefer Axis planes and I use a "MFFB" stick. I already have buttons 6 and 8 mapped for Prop Pitch. What do I need to do to get "hands off" ?

AFIK, and I am quite the rookie, you just have to keep playing with trim until you get it. I have another question to follow up on this: Does trim setting carryover to your next session?

NO Trim setting does not go over to next game, it will start in the neutral position.
If you got your trim on a hotas rotation dial or slider, then a slight movement will do to put it back to the old position though http://ubbxforums.ubi.com/infopop/emoticons/icon_smile.gif

As for "recommended setting" there simply is no such thing.

Trim is highly dependant on speed and altitude, and every plane needs a different trim http://ubbxforums.ubi.com/infopop/emoticons/icon_wink.gif - thats just what it's for - trimming should level out every force on the plane so it will fly straight without any rudder / aeleron / elevator input (read neutral setting)
- at a specific speed and altitude -

Trim is (theoretically) principaly there to ease pilot load in steady state flight conditions so that the pilot doesn't have to constantly push or pull on the joystick to hold flight attitude (be it level cruise, climb or descent).

The procedure is (IIRC) attitude, power, trim. For any given trim setting, if you change power, intially speed will change, then the change in speed will cause a change in attitude and rate of climb. If you add power while in level flight, the plane will speed up, then start to climb unless you push the stick forward to maintain level flight. If you decrease power, the plane will slow down then begin to descend unless you pull the stick back (if you pull all power it will eventually stall regardless of stick input).

To alleviate the need to constantly hold the joystick to maintain a desired attitude, aircraft are fitted with various means of adjusting the aircraft's trim. Once you've set up a desired climb, descent or cruise condition, you gradually adjust your trim control to remove the need to hold the joystick all the time to maintain that state.

As the world we live in is dynamic and the aircraft we're flying (at least online http://ubbxforums.ubi.com/infopop/emoticons/icon_wink.gif) are not fitted with automatic pilot, we aren't able to completely eliminate the need to monitor attitude but we can set it up so that we have time to look at the map or instruments without coming back to an aircraft that's wandering all over the sky or plastered all over the ground.

Some aircraft in the game have no trim controls at all (I-16 for example) and many have no aileron or rudder trim, but in those that do have it, it is immensely useful in easing the strain on long flights.

Trim can also be used to gain elevator authority in pulling out of high speed dives, but be carefull with this as too much nose up trim at high speed will result in some very nasty blackouts.

Skorpie-

For LW fighters up to the tall-tailed 109s, there is no rudder or aileron trim; all you have is the elevation trim, or CTL+Up or Down arrows. I don't use the keyboard buttons, since I get at least 30 buttons on my HOTAS rig, so I have the elev and rudder trims set on my stick's (extra) POV hat.

I'd recommend using two of the three thumb buttons on your MSFFB for elevation trim, and reassign 'Weapon 3' and 'Weapon 4' to one of the buttons on the joystick's base, or do without them entirely, since you won't use them that much in a fighter.

Elevation trim varies with speed; your nose will tend to rise as speed increases. I like to trim for a slight nose up tendency at cruise speeds, and this allows me to keep decent trim during combat, when my speeds are usually a bit slower. I feel it's better to be trimmed nose high than nose down in most situations, but you can overdo it and stall out if you're not alert.

With the elev. trim at your thumb, though, you will be able to tighten your turns a bit by adding some nose up trim as you roll into the turn. Play with it a bit and you'll quickly develop a feel for your personal preferences.

Thanks horseback, http://ubbxforums.ubi.com/images/smiley/16x16_smiley-wink.gif That was just what I needed. I do fly a FW-190 also as a profile, but the other 3 are differant models of Bf-109's. I use two thumb buttons already for the prop pitch. I'll have to figure somethingout for the trim. Thanks for the input. http://ubbxforums.ubi.com/images/smiley/16x16_smiley-happy.gif

Horse on another note. On those turning fights I hit combat flaps; but that $^$#^ flap horn is enough to make you want to get shot down http://ubbxforums.ubi.com/images/smiley/blink.gif. It doesn't help that I use earphones either. WOW is that loud! http://ubbxforums.ubi.com/images/smiley/16x16_smiley-surprised.gif I will definatly try the other buttons for the trim. Thanks again

It's always gratifying to be able to help. I agree about the flaps horn. We need a keyboard command to mute the horn, like the CTL+D command for the reticle dimmer.
