Must have, lucky VS-41. Time for a little TJBQ-MUGM love.

[b24_witchcraft]

Very nice and thanks Dino. Looks great even if it is only in Beta stage.

[orionll]

Carrier in sight.






Landing on a pitching deck is hard...



Probably got a rolling one wire.

[fsafranek]

A beautiful beta release. Really like the engine sounds in front of and behind the aircraft.

A few shots while launching and trapping on the Enterprise.

Had a quick hop - speechless, Dino. Super sweet model, great textures. Am not super familiar with this bird, so will be a great learning experience. Thanks for releasing it as BETA - it's already gorgeous.

Can't find the download link at all.

Absolutely beautiful as usual Dino many thanks. But as usual for me had it less than 30 minutes and I Free Willied it AKA broke it. I didn't even know the rudder folded down Ctrl-W. Now where did I put that manual.

[kdfw]

great plane, fun to fly, looks great.

[Dino Cattaneo]

Thanks for the appreciation.
I have just realized that the version uploaded is not the latest and greatest... but it is good for testing anyway...
Please take your time - I will not be able to do much work on it for a week or two. Target for final release is in early July.

This is a quick & dirty few fixes to help out Dino until the next update.
After a little testing, I found one significant bug that was fixable in the config file. When the S-3 was sitting on the ground, I noticed that with the external tanks full, the model listed to one side. On takeoff it displayed a definite fuel load imbalance. Checking the config, I saw where the lateral position of the tanks was the same. I simply removed one of the minus symbols and the issue is fixed.

(back up your original cfg before making any changes)
Here's the fix:
External1 = -36.0, -10, -4.0, 300, 0.0
External2 = -36.0, 10, -4.0, 300, 0.0 //<--the red showing the changed value.

The other thing I noticed is that the gear retraction/extension sequence seemed a good bit slow. After watching real retraction/extension sequences. I determined speeding the sequence up by half would do the trick. The adjusted valuesare in red:

point.0=1, -20.00, 0.00, -5.45, 1600, 0, 0.95, 70, 0.862, 1.96, 0.5100, 7.4, 7, 0, 260.0, 260.0
point.1=1, -38.00, -5.75, -4.5, 1700, 1, 1.06, 0.0, 0.606, 1.4, 0.5456, 7.2, 7.8, 2, 260.0, 260.0
point.2=1, -38.00, 5.75, -4.5, 1700, 2, 1.06, 0.0, 0.606, 1.4, 0.5456, 7.5, 7, 3, 260.0, 260.0


Also made minor changes in the Autopilot to get a slightly more responsive turn rate. You can just copy & paste the entire section:

[autopilot]
autopilot_available= 1
flight_director_available= 1
default_vertical_speed= 1500.0
autothrottle_available= 0
autothrottle_arming_required= 0
autothrottle_max_rpm = 90
autothrottle_takeoff_ga= 0
pitch_takeoff_ga = 8;
max_pitch=10.0
max_pitch_acceleration=1.0
max_pitch_velocity_lo_alt=2.0
max_pitch_velocity_hi_alt=1.5
max_pitch_velocity_lo_alt_breakpoint=20000.0
max_pitch_velocity_hi_alt_breakpoint=28000.0
max_bank=30.0
max_bank_acceleration=3.8//1.8
max_bank_velocity=6.00
max_throttle_rate=0.10
nav_proportional_control=11.00
nav_integrator_control=0.20
nav_derivative_control=0.00
nav_integrator_boundary=2.50
nav_derivative_boundary=0.00
gs_proportional_control=9.52
gs_integrator_control=0.26
gs_derivative_control=0.00
gs_integrator_boundary=0.70
gs_derivative_boundary=0.00
yaw_damper_gain = 1.0
yaw_slip_control_gain=0.000000
yaw_control_uses_trim=0.000000

[Dumonceau]

Mille grazie for this Dino! Just gave her a quick spin and she is a beauty!

[Dino Cattaneo]

You are welcome...

One thing on the gear retraction time - it is set to 14 seconds because the flght manual says so...

[alain0568]

--Big thank you,Dino!

Another version of VS-41 in Lo Lo-Vis texture.

Great job on the Viking Dino.

[Dino Cattaneo]

Thanks for the appreciation!

Apparently the Beta seems to work fine apart from some minor defects - no strange surprises or behaviors... I'll wait some days before making any further change but as of today the fixes are really quick to implement... maybe we'll have version 1.00 released before the end of the month.

[rsgunner]

This is the setting I use for vLSO.

[Aircraft.1]
ATC_model=S3
Type=Viking
Name=S-3B
Slow=8.2
Fast=6.2
AbeamClose=0.9
AbeamWide=1.1

The abeam settings are from the S-3B NATOPS.
The slow fast is from the T-45C. I am not sure what the actual settings are.

[Dino Cattaneo]

Well, the onboard AoA indexer is slaved to the Angle of Attack in degrees as follows:
- Green Chevron light 15.5 degrees or more
- Amber "Donut" 14.0 to 16.0
- Red Chevron light 14.5 degrees or less

So donut only is 14.5 to 15.5 degrees - that would be the same as the real thing if AoA units and AoA degrees were the same (but they are not...)...
BTW I would be open to change the default values if other values make more sense...

Hallo Dino,

congrats to your newest masterpiece!!!
Such a nice surprise for me this morning. It is already a real superb recreation.
I know, that you are no friend of making a paintkit for your models, but have you considerd to make a white clean paint for your S-3??
I think that there are many repainters, who would like to make more real-world and some fictional repaints for this beauty!
Looking forward to every gift that you present to the sim comunity!

Christoph

[Victory103]

Anticipated beta release, looks beyond good right off the shelf. Hope a VS-30 paint is in the works (AA 702 would be exact).

[StormILM]

Dino, regarding the gear retraction/extension time, I saw that value in one of the S-3 manuals as well but from my memory of seeing S-3's at different airfields, the gear movement seemed much quicker. Finding good reference video showing the gear sequence doesn't seem easy to come by but in this early promotional video, you'll see a runway takeoff at !:48 followed by first movement of the left main gear actuator arm at 2:08 and the total sequence appears to be around 8-9 seconds(on actual gear movement). Another video I saw showed about 7 seconds.

[Dino Cattaneo]

I had no doubt you were right - I was just saying I got the 14s time from the flight manual...

[Montie]

Thanks Dino, love it already

Out of TJBQ bound to MUGM the VS-41 Shamrock goes Excellent work Dino.
