Cool, dont think I've ever seen the nose wheel spin freely like that after trapping on any other model.
Been watching this one for a while, cant believe how fast its coming together :guinness:

Craig.

ps. whos arm do the FSX guys have to twist to get that Majestic class carrier. Don't know if it would even be possible but it would fill a gap in the carriers available:kilroy:

It has come together fast because of all the very helpful folks here doing the research, finding the reference pictures and data needed so that I could spend my 8-12 hours per day modeling. The support and involvement has been awesome. :applause:

The nose gear is setup as non-steerable except by brakes or differential power. So as a free wheeling gear, once the aircraft is pulled backwards, the gear spins around to follow the movement.
For those without pedals or wheel brakes, you can modify the contact point 0 as follows:

From this: point.0 = 1.000, 14.087, 0.000, -7.668, 1950.000, 0.000, 1.050, 180.0, 0.1500, 6.470, 1.000, 6.000, 6.000, 0.000, 150.000, 150.000

To this:
point.0 = 1.000, 14.087, 0.000, -7.668, 1950.000, 0.000, 1.050, 45.0, 0.1500, 6.470, 1.000, 6.000, 6.000, 0.000, 150.000, 150.000

This will eliminate the spinning gear as well as making the nose gear steerable.

EDIT: Attaching pictures illustrating tail hook coordinates at the pivot point.
 
S2Turbo Performance Data Needed

Does anyone have performance data for the S2T military version? That would be a great help.

Milton,

Here's a little info. I'm still searching.

The S-2T were all converted from the S-2E or S-2G while they were assigned to the ROCAF. The original plan, valued at $260 million USD, called for conversion of 32 S-2T (from 25 S-2E and 7 S-2G). Two S-2G were first sent to US for modification to the S-2T standards by Grumman (later Northrop Grumman). The first flight took place in July 1988 and the two converted aircraft returned to Taiwan in August 1991. The rest of the fleet were then converted in Taiwan using kits supplied by the contractors. The S-2T conversion program turned out to be a political scandal and it was probably for this reason that only 27 aircraft has been converted. (In 2001, eight ROCAF officials involved in the S-2T scandal were impeached, including former ROCAF CinC General Kuo.) The most significant improvement of the S-2T over the old S-2E/G is that the original Curtiss-Wright R-1820-82 piston engines, each rated 1141 kW (1530 shp), have been replaced by two Garret TPE-331-15AW turboprops, each rated 1227 kW (1645 shp), with four-blade propellers, resulting in an increase of 500 kg in payload. New mission equipment includes the AN/AQS-92F digital sonobuoy processor, A/NARR-84 99-channel sonobuoy receiver, Litton AN/APS-504 radar, AN/ASQ-504 MAD, and AN/AAS-40 FLIR (replacing the search light on the wing).
 
Milton:

At least in FSX I don't get any hook engagement unless I reduce the minus verticle value of the hook to 1.8 ft or so. Anyone have any experience with this in FS9, as I don't have any arrestable carriers in that sim anymore.

Cheers: T
 
What are the hook settings that Milton has, I do'nt have the model so can't really check with show markers, I am using FSX

Milton is it correct that i see no spinning props?

Hmmm, looks like I may have left the spinprop bmp out of the S2F-3 package. You can copy that from the E-1B package.

EDIT: Oh wait! You are in the E-1B. Then you must be in FSX. Let me adjust that for FSX.
EDIT2: Hmmm, I see the prop fine in FSX and FS9 so I do not know what you have there. The spinprop.bmp is the texture in question. Check that you have it, that it is 32-bit, and the alpha channel is near black with a faint blurred prop inset.

Flying in FS9 (FS2004) not FSX :kilroy: also i do have the "spinprop.bmp" texture in the texture folder.

Marcel

EDIT: The alfa-layer is completely black (color 5,5,5), not faint blurred prop inset.

Fliger747 is doing the flight model and is testing the effectiveness of the new coordinates and lengths I posted on the previous page.

Check your PM's please.

Hmmm, that must have gotten changed somehow. Borrow the texture from the A26B/C or any 3 bladed aircraft and rename to spinprop.bmp.

EDIT: And, thanks for the performance data from "Jane's" :)

Works, got the texture of your Grizzly :) btw seems the "faulty" texture is also on the Tiger Cat so far i could check...

I get the hook to engage with a verticle entry of -1.8 in FSX Accel. Interesting that on my laptop I get the black disks for props but works just fine on my "Mainframe".

Thanks for the info on the turbine aircraft. Empty weight seems a bit low? Any info on the empty weight of the military aircraft?

Cheers: T
 
Working on the S2T CDF Variant

Got the basics done, now to clean up and add the small elements, then map the fuselage and nacelles for textures.
 
Forgive me for being ignorant but have any of these creations been completed and released yet for fs9? or am i jumping the gun a bit either way great work guys

Kind Regards

Hooky:salute:

You jumped the gun. But no harm done. I know that ALL of us are anxious to add another Milton Shupe Work Of Art to our FS9 aircraft collection.

Hi Milton, This is what I have for the hook settings, you can see with the red cross where the hook catch point is and the small white light is the hook attach point on the fuselage only did SOH-S2F3 so far but threw in cat launch settings for FSX Accel. The virtual hook catch point is slightly in front of the visual hook as it seems it hangs vertically but the visual does not.

One pointer that the hook length is to short it will go through the deck/ground whereas it should stop at ground level with the hook sitting on the ground/deck

One thing I have found with a few trike gear models is the damping needs to be less than 1.0 as when the nose gear hits the deck it flips you over backwards, I have it as 0.900

Replace the existing [TailHook] with this one, copy pasting the [launch_assistance] entry in at the same time.

See what FSX users think of it the cat launch is obviously no good for Fs9 and your hook settings should be ok with the Carrier Opps COPv2 gauges which I would go for in Fs9

[TailHook]
tailhook_length=7.6 ;(feet)
tailhook_position=-20.976, 0.0, -2.533 ;(feet) longitudinal, lateral, vertical
positions from datum
cable_force_adjust=3.0

[launch_assistance]
launch_bar_pivot = 10.6, 0.0, -5.3
launch_bar_lug = 12.9, 0.0, -7.3

Cat launch hook up point is just behind the nosewheel where you see the white light

Regarding sounds for the S2T, I borrowed the KA350 sounds for testing but I hope we can do something better. They may be realistic (if so, okay) but if not, ... maybe someone can recommend something else.

I'll take care of Turbo Stoof's sounds Milton.

Ah, thank you so much Rich. I have sent this data to Fliger747 to test out. That is helpful.
He is pretty close to what you have now.
It is interesting that the cfg does not ask for angle, and that makes the catch point a bit of guess work.

Do I understand correctly that the launch assistance is only available in FSX?

The visual model launch coordinates are 7.178, 0.0, -5.19 but I suspect they are not used.
