So,i have to purchase the game, with the disc?
I thought i can buy it online,Steam or something..

If you don't have the CFS3 discs then I think you'll need to do a complete CFS3 installation first. Then you can uninstall CFS3 after WOFF has been installed. However, if you ever have to reinstall WOFF (which I've had to do several times over the years) you'll need to reinstall CFS3 again.

Yes, but the question is : where do i get ( online - download ) CFS 3 ?
I can't find it on Steam or somewhere else. Only Amazon ..
Should i buy it from here ? What do you mean ?

I suggest that you refer to the WOFF FAQ file. Go to HELP page on the WOFF site. Then download the "latest FAQ" file (on the first line). Items #10 and #9 in the FAQ file discuss where to obtain CFS3 and how to update to the proper version (if needed).

I will find a store here in Germany, to buy it.
Does the game ( WOFF ) support 3840 x 2160 resolution ? I hope so
Thank you

I purchased the CFS 3 from a local shop, second hand, 2 euro
So i installed WOFF, but i have some problems.
First, i cant find the menu how to configure my joystick / HOTAS, and second, how do i quit / exit the game ??

Bronnx, the manual for WOFF is available as a downloadable PDF on the OBD website;
here is the link.
There you find your questions answered; for exiting the game, see point 13; on page 21.

"Wings Over Flanders Fields" - Frequently Asked Questions

"Workshop" menu to get to many options including configuring controls and controllers. ("ReMap Keys/Controllers" button) See the FAQ as Olham kindly points too. Many of your questions have been asked before and are covered in some detail in the FAQ document.

How to install, CFS3 what is needed etc. NO usually you do not need to install CFS3 if you have it on disk (only install if it's a very old disk as it needs updating to CFS3.1 first). Anyway check the FAQ please.

If it's a downloaded CFS3 then you'd need to install it first if it's not in an ISO format that could mount for example.

It seems to be very difficult to assign the throttle. The image is flickering as hell for this menu, its hard to explain
As a first impression about WOFF : i like it a lot. The only think i dont like it, is the way i have to configure all the buttons.

You need to select the joystick in the selection frame;
then the best is IMHO to "unbind" it from all and any commands.
Do the same with your rudder pedals, if you use such.

Only then, you should select each command, and "bind" it to the correct stick function/button;
then do the same with the pedals.

I have no peddals yet.By the way, would you recommend peddals for WW1 and WW 2 sim flight ?
Thanks, i will try as you said

I attached a printscreen. The menu labeled with black is flickering very very fast when i select Rhino Throttle.
My HOTAS is working fine with every other sim flights i have
No idea how to fix this

I find the "reality feeling" better for WW1 crates, with using rudder pedals.
(For WW2 planes, rudders are not so very essential IMHO).
But when I started, I used a twist stick and it worked well.
I guess it is also a matter of the cost - pedals aren't cheap.

Here is a graphic to explain the setup:

i will have to fix it somehow
Are there some good mods for this game?

Yes, there are.

Firstly remove all axis that are assigned to that controller first, then add the thing you need only.
