No problem , what scale you want , maybe 1/4 ?
Now I will make the wngs ( the work is faster) then I will cut the model for me , for tests in 1/4 scale. Then I will make cowl , gun canopy , and I wonder how to make the cockpit canopy , maybe from wood , I don't know yet .

Thanks Dave !
I made the airfoils of original wings in the root NACA 23015 and NACA 23009 in the tip of wing
So the wing will have the original foil , What you think about this my decision ?

When I made a wing for a smaller 1/7 FW 190 I considered the Selig airfoil and added a slight washout to improve slow speed handling. Using Compufoil you can see the aoa and estimated stall speed. So by overlapping the aoa range between the root foil and the tip foil I was able to add very little washout while prolonging the stall.
Since your thinking of using the actual scale airfoil be sure the retract mechanics fit the airfoil because usually the model wings are slightly thicker than scale. Maybe at 1/4 scale this isnt a problem, I dont know, just something to consider.

I made 11 wing ribs from NACA 23015 to the tip in NACA 23009 and putthe angle 2 degrees . My program can't make different angle between root rib and tip rib.....
This is the result:

Look up Compufoil. It will create the ribs for you then you can proceed from there.

My concern for your wing is the AOA of the tip foil and the stall character of the plane. Look up the stall info of the tip foil your using to see what the neutral range is and what the stall angle is. A very small washout adjustment within the neutral range will help the stall performance without making the wing look funny.

Thank you very much Chris, I can't understand all your post but I made the correction and now the root is +2 degree and the tip foil is zero dergrees as the original 
I will check Compufoil thank you !!!

Good work Mr fokke.
What Chris is saying is to just make sure you build a little bit of 'washout' into the wing tip for better low speed (higher angle of attack) flying so the tip does not stall before the rest of the wing.
Great model and workmanship mate.

The full size has 3 deg washout anyway so why not just copy that? I'm guessing they knew what they were doing, and it wouldn't be 'scale' with anything different...

Hi guys,
Brad ,that's is what I made . I made the 'washout" , in the root is +2 degrees , then in the tip is zero. This modification is not only for better low speed , this I made and for better work of ailerons in up position, because if we don't have washout in this area the aileron will work good only in down position!
Evan , on the original the angle in the root is +2 degree , I use factory drawings and germany documents about this , my information is this

I put the drawing of Sierra landing gear it to the plans, so I made position . I choose Sierra because that are strong and are 1/5 and 1/4 scale gears

Guys , can you help me with two dimensions of FW-190 Sierra gears in 1/5 and 1/4 . I need to know the lenght and the height of the main plate of gear ?
Thanks in advance

HI
I start to make the wing ribs of the wing, I use for more reality the real plans of the A5 . Off course I have more work on the ribs and make stringer holes .

Bruce, I will use laser cut CNC on 4mm plywood , the laser will cut and draw the ribs. I think about to use and other material for the ribs , something composite , but I am not ready with the test yet
Thank you Ramstein, as on my picture , thanks again !
