Hello Gents,

The aircraft I'm refering to in particular is the "Hunting/BAC Jet Provost T.Mk5 V2.0 Package" by: Mr. Rick Piper. As with all of his
aircraft, she's a beauty. I seriously doubt this has anything to do with his aircraft. but with that being said, it's the only fixed wing
aircraft that I have this happen to and also I've noticed it with the choppers.

Anyway.. short story long, as far as the choppers, they fly level but they keep veering to the left. just like your giving it left rudder.

The Jet Provost does the veering but also pitches as well, to the left. ,, Have you guys heard of such a thing or had it happen to
you?

Thanks,
Dwayne

I know the reason choppers do it, the veering thingy, is due to the main rotor torque not being balanced properly in the models by the tail rotor. This is actually a correct behaviour of helis, and you can trim the yaw out once you acheive cruise with your rudder trim. The SH-60 and other modern helicopters don't have this problem to the extent others do due to the canted tail rotor. There are ways to change the .air and Aircraft.cfg files to make it fly straight at cruise speed, which is normally about 10kts IAS below Vne. There are articles on Hovercontrol's website that explain this in detailed, yet very simple terms, so morons like me can understand it

The HC website also has a nifty program, HelicopterTotalRealism, or htr1.5 that you can run alongside FSX or FS9 (also called FS2004 COF), that adjust many of the helicopter parameters in realtime as flight confitions, power, collective, cyclic etc etc change, using FSUIPC.dll. Another program that does the same thing, but IMO not as well, is Heliforce 1.0, also available on HC.
HTR also includes a wonderful PDF file the explains how it does what it does and what effect changing certain paramerts will have, basically a tutorial on "How Heilcopters Fly".

As to the fixed wing, could it be the P factor is modeled a tad too high on that model? Or perhaps it's accurate to the plane and OTHER fixed wing birds don't model theirs high enough. Or perhaps you have changed the P factor slider lately and didn't realize it? Those are some alternative explanations I can think of right off, I hope something in all this babbling helps you

EDIT:
OOPS! I just reread your post....is the plane a jet? If so, then P factor isn't a factor at all! LOL! Sounds like a W&B problem. Did you look at the Aircraft.cfg file to see is there is an inbalance? Perhaps one wing has a load the other doesn't, the COG is in the wrong place? Typo's happen and it could be the author messed up someplace? Maybe a problem with teh .air file's stabilizer settings too? Just suggesting possibilities....
I'll look at the plane in more depth tomorrow, now I am off to bed with my lovely wife

Good luck and happier flying!

Let me put you STRAIGHT on this one, Dwayne... ....

..so I'll get STRAIGHT to the point....

I have the wonderful FS 2004 "Hunting BAC Jet Provost" running on both FS 2004 and FSX, and in both versions it flies as STRAIGHT as a die...

Perhaps your Co-Pilot is a little heavier than you thought?

Paul....(Its difficult trying to be STRAIGHT-faced!).... ... ... ...!

Oh Paul, how could you, and at this time of day???

Paul do it anytime, every day

"Strait"...>>> http://en.wikipedia.org/wiki/Strait

The narrow passage-way between two large Mammaries....

...I reckon.... ...!

Paul.... ...!

I'd say you've got that definition STRAIT

Personally I think this thread is going STRAIT into the trash, but what do I know??

Have a fantastic day all!

Pat~

Yes!

"Bass Strait, which lies between mainland Australia and Tasmania, and depending on definition, either connects the Indian Ocean with the Pacific Ocean, or connects the Southern Ocean to the Pacific Ocean."

...personally... ....

I much prefer negotiating my way carefully through the Strait dividing the left Mammary and the right Mammary.... ...

But that's only me... ...!

Paul... ... ... ...!

...makes me curious to know where the "North West Passage" is?.... ....!

Thanks Guys!

I'll see maybe it is the wait oops, I mean "weight" balance.

All you guys Pick'n On Me! ... ,, No respect I tell ya, no
respect...

The way I look at it is you don't pick on someone you don't like. So
pick on me all ya want guys.

.... ... ... ...!

We are an awful lot, Dwayne!.......but its all done in fun, 'cos we know you are a really fantastic Bloke, and you will see the funny side of it... ...!

Part of the fun of Friendly Forums!..... ...!

Paul.... ...!

I get the same done to me, when I make daft spelling/grammar mistakes...so you are not alone!... ...!

Yes we love you Dwayne, and we are sometimes called "funny talkers from over the pond"

I assume you have checked the aileron and rudder trim haven't you ?

Sorry no smart a** comments because it's late and I'm too tired to think up any !

I never thought about the trim, I just presumed he'd have those STRAIT, Strait from the start of the game!

Glad Gringo cut STRAIT through to the heart of the matter!

And now I'd best head STRAIT to flying or the lovely wifey will set me STRAIT fast!

And now I've run this all STRAIT into the ground, I'm off, great day all!

Pat!

Thanks for the love guys. Back at ya 110%.

As far as the british being "funny talkers from over the pond" I have to disagree.
I always thought the british accent was cool. Hell I've tryed many time in my life
to imitate it but.. .. awful.. just awful!

I wish I could get it down cause american woman love it. You know what I'm
talkin' about!...

Thanks for the idea Gringo but Pat's correct, All trims were 0.0. I have to get on the
ball. I still haven't booted up FS9 yet to see about the possible balance issue.
