The SAAB Viggen released!

[hschuit]

Ian, the link with the P3Dv4 updates I provided a few days ago is just a simple ZIP with only the new/changed files.
For the full native FSX pack, search the AVSIM library for: alphasim_viggen_fsx_native_v2.zip

Many thanks Henk, very much appreciated.

I have been reading up on the SFI AJ37 flight manual and with the help of part 2 (formely secret) done some adjustments to the fuel entry in the cfg file in order to replicate the capacity and location of the tanks on the Viggen. this has also been done to the location of the store pylons. The current hot rod have the Jakt Viggen engine power and this is not realistic for the AJ/SH, I have made a separate folder for the AJ/SH/AJS models with the RM8A engine. See entries below

Change the fuel entry:

[fuel]
//Longitudinal (feet), Lateral (feet), Vertical (feet), Usable(gallons), Unusable (gallons)
//5000 liter intern + 1500 liter extern
fuel_type = 2
number_of_tank_selectors = 1

Any feedback on these mods are welcome!

For me the aircraft wobble back and fort in the yaw axis at lower speeds (both before and after my mods), do any of you fm guru's have some advise to make it more stable?

[Bjoern]

I'd say check your vertical tail area and location. Or simply crank up yaw stability. Or add a yaw damper.


If you want to fix the problem at its source, this is your guide:

Thanks for your great works, Henk and Jens!!!

DennyA, here is a P3Dv4 update which includes a new HUD and XMLTools loadout manager. The morons at Rikoooo "borrowed" our files, repackaged them and put it on their download site without asking permission so I am not going to release an official update package on AVSIM. The P3Dv4 update requires XMLTools (freeware, Google for it if you do not have it yet). I also do not have time to explain in detail how to install the P3Dv4 update so I would say stay away from it if you do not have some understanding of the P3Dv4 file structure etc.

Henk.

Hi
My thanks to everyone involved...
Installed version 2 (only using P3Dv4) Ok all but no functional HUD. Installed P3Dv4 update, now have HUD but lost startup (smoke,etc) and afterburner effects. Unableto find why...Please help
Best regards

Any chance for the re-mapped (fixed version) to be done for fs2004 as well since this addon was originally for that platform?

[JensOle]

Henk is the mastermind behind the model rework. But I think the reworked model has moved so much away from the FS2004 format that it is not a straight forward job to make it FS2004 compatible.
