trim questions
« on: February 02, 2000, 10:37:00 AM »
Last nite I started to use the manual trim in some of the furballs (knights down to 3 fields, no dar, within 2 hrs rule the arena, thats a momentum shift) at times it seemed to really help other times I felt like it really got me in trouble.  Do you Experten use the trim all the time?  Sometimes it seems like my stick freaks out, MS SW FF pro,it is a pain to recal all the time, think I will look at the logic tech stick.

I have problems with trim myself. After a VERY long time flying without using any sort of rudder control. I've managed to get a stick with twist so I can control rudders. Now I find myself spinning almost constantly and me E state suffers alot more than it did.
I would appreciate any and all suggestions on when to use rudders and when not to use rudders in flight.

Thanks in advance!

Well, I ain't no experten, but...

I use trim a lot, but mostly auto trims.  (Some call it auto pilot.)  Climbing out, I am in "speed" trim, enroute (or running on the deck) I am in "level" trim.

In a fight, I'll use "angle" trim, or the manual trims.  In a straight dive or zoom, I unload and set "angle" trim.  This keeps the plane trimmed as the speed changes, and minimizes E loss.  When I have to maneuver during a large speed change (B&Z), I use the manual elevator and aileron trims, always trying to keep the stick near center.  This gives me more precise stick control.  In a turn fight, I will sometimes use manual elevator trim to keep the stick near center.  The second that I am out of the fight, I will set one of the auto trims to maintain trim and E.

I have the auto "angle" trim mapped to a button on my throttle, and the manual vator and aileron trims mapped to a hat on the throttle.  So, I can be trimming with my left hand, while flying and shooting with the right.

Note: you can use the manuel trim while in angle trim mode,i.e. fine tune adjustments when auto-angle is set in dive, you can adjust it manually...this helps if you have a FW190 ,believe me!

No experten here either but can hold my own usually.  I used to fly the 51 predominantly and was trimming the plane constantly as my E state changed.  I used the auto-trim features for climbout and cruising prior to any engagement and once I found an enemy I would use elevator trim and aileron trim all throughout combat.  I never mess with rudder trim during combat.  Mostly I trim nose down as I dive in and nose up during the zoomup.  I found that using the elevator trim(nose down/up) to line up the shot a much more precise way to aim than trying to line it up with the joystick.  I will also trim out any tendencies for the plane to roll using aileron trim as my speed changes.

I have a CH ProThrottle and have mapped the aileron and elevator trim to one of the hats.  It was a little odd at first since I never had to worry about trim in AW but it is now something I do without thought and it does make a world of difference.

I have attempted the fly the FW offline and find myself either in a spin or stall, it seems like you need to be very gentle w your control inputs to be very successful with it.  I am in the 205 now because is seems a little more forgiving.

Not that I am an expert pilot, but here is what I do regarding manual trim:

I use aileron and elevator trim the most when dogfighting, so I have both mapped to my joystick & throttle on seperate hats that are manipulated by different hands.  The important thing is that you need to be able to trim both at the same time.  If you use the keyboard and have difficulty manipulating the four trim keys at the same time with your left hand, you might consider remapping (I dunno, never used the keyboard).

In general I try to let auto-trim set for me when possible.  I start manually manipulating trim during dives and climbs and especially if I feel out of trim when saddling up behind someone for a shot.

At low speeds, such as after climbing to reach a fight, your plane will have a lot of leftward roll.  Auto-trim will trim your ailerons to the right to compensate.  It will also trim your elevator up to generate the lift to keep you flying straight at that speed.  As you dive and begin to pick up speed, you will start to notice your plane rolling to the right as it gets out of trim.  At this point I start manually tweaking aileron trim to the left.  In addition, you will start to feel your dive shallow out as the upward elevator trim tries to make you climb.  When I start feeling this, I tweak the elevator trim downward.  When you get going very fast at the bottom of your dive, your elevator and aileron trim settings will be set pretty much in the middle and you will be flying straight as an arrow for a shot on whatever target you are bouncing.  When I climb again you simply reverse the process, or finish with an auto-trim at the top.

Doing that whenever my speed goes up or down pretty much keeps me in trim for a steady shot whenever I have to take one.  If I ever do feel out of trim when closing on someone and hitting auto-trim isn't feasible, I tweak as necessary there.  

Keep trying at it and after awhile you will get the feel for when and how to manually trim your plane.  Soon it will become second nature.  I don't ever think about it now, its just something I do automatically.

YgsMilo:
I don't even think about trying to turn in FW unless speed is over 250 and I never loop in it, hammar heads only.  It's the  most difficult plane to fly in Aces High, for those who don't think so, try doing it for a week straight...I like the challenge of the FW, I fly it for 75% of my sorites, but it has some shortcomings that I hope will soon be addressed by HTC...don't ask me what they are, just fly it for a week and you'll know what I'm talking about.

So do any of you use rudder at all except for take off and landing??

Yup...frequently while trying to line up a snapshot if the target is a bit off the nose.

I use rudder while flying, I just don't adjust rudder trim save for when auto trim does it for me.

A note about rudder use:

In Aces High, large slip angles will about stop you dead in the air.  If you hit full rudder in either direction, you WILL drop to 150 IAS or so in a big hurry, and likely spin in a plane like the FW.  I do use rudder, but I scale it down heavily.  I use a curve from near-0 to about 50% up until the last 2 sliders on the rudder, then I ramp those two up in even steps to the top.  This way I use the rudder for the fine adjustments, and I use only the last bit of stick twist travel for full rudder deflection.  Only use full rudder deflection as airbrakes, because that is their effect in AH at the moment.

Just be aware, if you are trying to stay fast, using a bunch of rudder is going to blow all of your E.  Be vewy vewy gentle on the rudder or scale it back a bunch.

Another thing to note is that during low speed turns, your plane will have a tendency to incur some slip and you will need to hold some rudder to help your plane cut thru the turn.  If you continue to turn without using rudder, your plane will not turn as effectively and will thus not hold its E as well.  Its a two sided coin.

Thanks guys.. having never used rudder wasn't sure how it affected my flight. Guess I'll have to scale it down a lot so I can quit killin my E
