FSX S2F3 Stoof update

With regards to trimtabs, as stated above they always move opposite the commanded position. Remember, as the air flows across the trimtabs, forces will move the controlled surface in the opposite direction!

In fact, if you want to be more "realistic," you'll apply the trim setting to the control surface as well while at speed...

At cruise speed for example, a small amount nose up trim will result in a small amount of down trimtab, which then in turn will force the elevator up by a similar amount...

...in effect, the trimtab will then be horizontal to the aerodynamic waterline of the aircraft!

Using a speed based scalar will allow for a smooth transition from slow speed to cruise speed, 'cause you don't want the control surface(s) suddenly snapping into position... :wavey:
 
As some things got lost in the FDE translation for the new plane, some mods are on the way. Indeed the viewpoint was a bit too far back as it was originally set before the headrests were installed.

Cheers. Tom
 
Ok, next beta with updated files will be up later after I get off of work. I will contact the testers so they can get the latest.
 
euroastar,

You might include the attached in the package; updated docs, effects, and flight model.

Thanks
 
A quick one for Fliger747,

Tom, you might want to look at the dimensions of the -3 (S2-D) according to the airfile/cfg

1. Aircraft length is 55.84ft where in reality it was 43.5ft (1.5ft added just aft of the cockpit area compared to the -1/-2's 42.0ft, unless you are counting the MAD boom),

2. Wingspan was also lengthened to house the ESM sensors in the tips, span goes from 69.80ft to 72.80ft.

3. Wing surface area from 493.00 to 499.00 sq ft,


finally I had added this to the bottom of the [propeller] section to give the correct location of the prop hubs

minimum_on_ground_beta=1 minimum_reverse_beta=-14
rotation = 1, 1
propeller.0= 2.0, 0, 0
to
propeller.1=2.0, 0, 0

I apologise if I am stepping on your toes.

Bruce,

Thanks for the heads-up on the dimensions.

The propeller statements should actually be the thrust locations which are as follows:

propeller.0= 7.798, -9.0, .026
propeller.1= 7.798, 9.0, .026

We appreciate your interest in helping us to the finish line. :applause:
 
I did note in the first beta presented that the CG was way off, something in the translation to the new model, the CG was at the leading edge, rather than near the 25% MAC, which probably accounts for some wierd pitch tendency. I had not provided and tested a specific new FDE for the new model, so I expect some translation of coordinates was responsible. Because of the great number of variants, the original betas for each often rely on a previous version and then have to be modified to fit. Takes a while, so Beta comments on stuff we have missed is great.

Just sent Milton a new set of files this morning, which should fix a few more minor issues.

Cheers: Tom
 
Try this: Also flap lift reduced slightly to allow a slightly more nose up landing attitude.

As was brought up earlier with regards to the trim tabs and elevator; the tab moves in the opposite direction to the control surface. The issue arises because FSX adds a pitch or yaw moment in reaction to the tab application, and the animation generally moves the tab. For an aircraft at rest this looks OK, however in flight the tab should displace the flight control, ie. down elev tab should result in up elevator. Not even some recent high end payware aircraft have figured this out currently. For aircraft with hydraulic controls it might work to animate the elevator deflection to have an additive to the manual position input. At autopilot cruise the plane in animation is really flying off the tabs and not the elevator position.

Bit of an issue, due to the way FS treats elevators.

I'm really enjoying this:applause:
Just a comment on the props where the vertices of the prop model can be seen, I believe that if the texture is a little smaller than the prop diameter you will lose the polygonal appearance at the circumference.

Pretty stable deck approach at about 85 knots. Mostly tested aboard Nimitz, but some aboard straight deck Valley Forge.

I'm going to plug the numbers into VLSO and try it out when its ready - it sure looks good to a Grumman fan
 
Euro:

Noticing with the right light angle a reflection off of the engine, looking as if has a glass window across the cowl opening, remains with the engine shutdown.
 
Will check it out first thing in the morning. One thing I can't get to work is the mouse react for the recog/searchlight, its animated in sim but no mouse reactions to it..will check that out as well. Keep up the great work gents.
 
The updated MDLs for the exterior and VC has the animated inner flaps. If not, I uploaded the updated MDLs. If still not working, I will check into it.
