Yes, you heard right! I've managed to fix that awful trim problem. I've added a bunch of other fixes & enhancements too:

Note: These modifications do not require the V-One gauge to be installed.
Any user with a modified flight model will need to adjust the CG offset for proper auto elevator trim.

Now available in the Avsim Libray, search for:

Many thanks to Markoz for you time and testing  ;)

thanks a million Paul. I have the Micheal 2 mods installed. Will your mods play OK with those? Much appreciated. Thanks again.
Cheers,
Brian

There shouldn't be any issues at all. Give it a try and let us know  ;)

We'll do

An update to the installation:

The XML files are in the wrong directory for the -100F, -200 and -200F.
The -100 is in the correct directory.

The '727_various_fixes.xml' needs to be moved to each respective \panel folder:

FROM:
..\Microsoft Games\Microsoft Flight Simulator X\SimObjects\Airplanes\CS_B727-100F
TO:
..\Microsoft Games\Microsoft Flight Simulator X\SimObjects\Airplanes\CS_B727-100F\panel

Repeat for the -200 & -200F

Sorry about this but errors can happen  :-[

I installed this gauge and I have the Michael's mods on my fleet.   It seems to play nice.   I did have to make the CG changes to the file to get the auto-trim to yield a usable setting.  I will likely keep using manual trim setting in most cases, though.

Very nice job, fsxpaul!   

Looks to be an awesome fix. I will try this next time I do a serious CS727 flight.

Thanks, fsxpaul.

Thanks for the fix Paul. ;)

And thanks for all your help with testing Mark  ;)

Hi Paul, thanks a Million for the trim fix. However, I noticed that for take-off, the trim is locked, probably auto-trim is enabled? How can I disable it? Manual trim with the assistance of your V-one-gauge is great, so I don't need auto trim.
Thanks for your support.

Hi Chris,

The auto-trim is released when the wheels leave the ground, trim will adjust whenever you command after that.
But I did find an error that was locking the auto-trim while still on the ground.

Add the following RED item to the 727_various_fixes.xml in the <!-- Auto Trim Set --> section about 40 lines down in the code:
(L:TCAS_P13_008_BUT_POS_click, bool) (A:BRAKE PARKING INDICATOR, bool) and (A:SIM ON GROUND,bool) and (A:ENG HYDRAULIC PRESSURE:2,pounds) 0.0001 * 2800 &gt; and

Make certain to have a 'space' on either side.

Thanks for your reply.
Unfortunately, this hasn't worked out for me. I still have to take off with a trim that is locked to 0.
I love the trim-fix-program once I'm airborne. So my question: Is there a possibility to just delete the Auto-trim? I'd much prefer the old manual trim with your v-one-gauge. All of the other fixes are excellent.
Chris

I'm very confused as to why the trim is locked at 0? That's not happened to me in all of my testing.

Are you using FSX SP2 or Acceleration?

Did you make any other changes to the 727_various_fixes.xml file?

Are you using the Auto Altitude Alert set?

The trim wasn't locked at 0 for me either when I did the testing, or I would have pointed it out to Paul. :-/

Well, I just added the "and" as per your instruction. When it didn't work, I deleted the whole Auto-trim section. This worked trim-wise, however, the whole steering (front wheel, rudder, ailerons) was out of order.
Therefore my question, if there was a way to delete the Auto-trim while keeping all the other goodies.
Chris

PS: Maybe this has nothing to do with the problem: After start-up, I have to push Ctrl E in order for the GPS to work. (electrical state?)  :-[

Do you mean the front wheel, rudder and ailerons didn't work? My XML code doesn't control any of those.

Send me a PM and I'll send you a link to a version without the auto-trim.
Paul

I just downloaded the trim sensitivity fix and installed it.  It works great!  The 727 was nearly un-flyable until this change was made, but now I can adjust the rate of climb and only need to make minor adjustments as I climb to my selected altitude.   :) :)

I'm using this together with the V1 callout mod. Is there a way to keep all the fixes, but disable the auto-trim? I want to be able to set my own trim on the ground, not have the gauge do it for me. I'm using the FM tweaks, which move the CG around a little bit. The V1 mod thinks I should be setting -5 for take-off trim, and either that or this is over-riding me when I try to set the trim myself, and I can't take off.

Make certain to have a 'space' on either side and save the file.

Thanks, I'll try that when I get back in a few days. Just to be clear, I'm not even able to leave the ground, the trim is stuck at -5 and full up elevator means I can't even raise the nose to rotate.

Is there any way to just turn off the auto-trim entirely? All of the other fixes like the speed bug, GPWS, etc are fantastic, but I would simply like to control the trim and altitude selection on my own.

@fsxpaul.

I tried to reply to your PM, but I can't. When I try to send a reply, it says:

The following member(s) could not be messaged.
The member name(s) is/are either invalid, or they have you on their ignore list:

Funnily enough, no names, not even fsxpaul, come up in the the list! :-/

Not sure what's going on. I'll send you an email.

With the fix I've suggested, you should have no further issues.
As designed, the auto-trim and auto-alt-alert set will only activate when the Transponder Ident Button is pressed.

I'm currently updating the XML code to allow optional features to be activated.
Also adding EPR throttle hold via the EPR setting bugs.

Need some more testing before I release.
