HJG 707 series aircraft- trim problems ongoing

[tisac]

Is it a matter of microsoft Vista OS, or other reason why trimming these aircraft is a futile action.... My comp here is completely unable to get the 707 to fly without an out of trim condition consistenly shows that either has it flying with an excessive nose high attitude, or it comes screaming down in nose down tuck when flying at altitiude. It also cannot fly wings level without autopilot engaged as well.


thanks

I can't replicate your problem .... at all !

"ALL" of our B707 series aircraft trim fine .... and fly beautifully .... for me .... both in manual or AP controlled flight modes.

Whilst I have heard of a similar problem (a couple of people only though .... about 1 year ago as I recall) I wouldn't mind betting any problem you're experiencing may be related to your control device/s and however you've got various assignments and their sensitivities configured .... as I recall we advised on this case on this other occasion I mentioned.

Just on the subject of TRIM RESPONSE .... I want to remind folk that by far the best trim responses during manual controlled flight has been proven to be per use of keyboard commands "HOME" (Trim Down) and "END" (Trim Up) .... and which results is a roughly 100 FPM change in attitude (ROC/ROD) "per tap".

Some folk have reported overly sensitive trim response when using joystick or other control device configured assignments .... yet uncomparably smooth responses when using the above recommended keyboard commands.

On all of our the B707 series aircraft .... and during AP controlled flight modes only .... the Thumb Wheels (there are 2 of these located on either side of the AP TURN/ROLL KNOB .... if using the HJG/CARTY panels) should be moused ....which also results in beautifully smooth Trim response at a roughly 100 FPM change in attitude (ROC/ROD) "per mouse click".

At least that's precisely the kind of Trim response I'm seeing in relation to inputs during both manual and AP controlled flight modes.

I was right .... in that it was you with whom we discussed this particular issue with once before ....

In addition to my above and previous comments ....

I don't believe that OS have anything to do with your problem.

I'm satisfied nothing we've programmed is contributory to your problem .... otherwise I'd expect to see a forum full of complaints.

You should be using HJG panels with these aircraft .... but then again .... no problems ever became apparent during our tresting of these aircraft using HJG or MSFS default panels.

You should also ensure that you're using the correct AIRCRAFT.CFG and PANEL.CFG versions with your simulator of choice .... by default all of our aircraft download ready to use in FS2004, but, if using FSX, then the default F2004 CFG files should be deleted and the FSX versions then activated .... as advised per the installation instructions.

I use the Vista OS and I have been flying HJG's Boeing 707 series aircraft for a long time and never experienced any trim problems. Operating these aircraft at their proper air speeds and configuration is the key to their proper flying attitude.

I also recall of your difficulties ( complaints ) on several previous occasions.

Since I am not a member of the HJG team, I don't need to be quite as diplomatic as Mark.

Shame on you tisac, but it is my opinion, that you want to occasionally harrass the folks at HJG who have done such a mavellous job with all their aircraft.

Furthermore, I strongly believe, that you have only a very limited knowledge of flying, especially high performance jet airliners.

My advice to you, is to start reading up on operating procedures of high performance jet airliners.

Whenever I had problems with HJG aircraft it was always pilot error. You can't always just download an aircraft and take to the skies. Take the time to read up on the panels and handling notes.

[garryrussell]

problem is folks want realism but when they get it can't handle it simply because even the most basic instructions are not followed.

The first this to ask yourself Tisac is why the forums are not full of people with the same problem.

Here it is the OS or the model that suspect but the most common cause...operator is not on the list.

When you do get an issue look at what you are doing first instead of assuming it's the model

There is a terrible tendency now for people to want to alter CFG and the like because as soon as a problem arises it must be the fault of the model, dynamics or in fact anything or anyone other than themselves.

Two things to check:

Go into the FS9 key settings and make sure the key repeat slider is set to a minimum. Otherwise, your key strokes will quickly run the trim to a max/min. This is especially important if you have assigned a joystick switch to trim, as I do. Make sure the assignment is for a single keystroke, and that the notorius repeat slider is set properly.

Do you have FSUIPC???

As you reported the same issue last year, make sure you check all these settings again.

Trying to be diplomatic

I'll echo Garry here with my mantra -

Too High
Too Fast
Too Heavy

You are guilty of one or more of the above. Fix those and you won't have the problem.

And also, tisac, give us more information. It would be helpfull to know the specific values.

Your altitude.
Your airspeed.
The GW of the aircraft.
What is your loading configuration ( fuel in which tanks, payload etc.) are you in the Center of Gravity Envelope?

and what control device ( joystick, yoke etc. ) are you using.

Also,perhaps you could provide us with some exterior screen shots so that we can see the actual position of the aircraft flight control surfaces.
