I am building roaming research Mig-3. Love the plane but instructions are occasionally vague. Wanted to sanity-check washout and wing incidence

1. How much washout is generally there for a large WWII fighter plane? I end up with ~2 degrees or so
2. What should the wing incidence typically be relative to the stab? Plans don't mention it, and it appears that it is close to zero but I have trouble buying it fully

Specific info, no matter the exact plane as long as it's a WWII warbird of a similar conceptual design, will be appreciated: P-51, P-40, P-47, fw-190, etc.

Thanks.

Here are a couple of screen shots from the Top Flight websit showing TF design info. They don't include washout info though.

Hi!
Wash-out is something all full size warbirds have. If memory serves me right, the Spitfire had -1,5 to -2,0 degrees wash-out at the wings tips.
Wing flying at +1 to the stab.

2 degree's of washout works well for warbirds. If your running a simisymmetrical ( spelling?) airfoil such as a NACA 2415, I would set everything to zero incidense. If your running a fully symmetrical such as a NACA 0015, I would set the wing at +1 and the engine at 0 and the horizontal at 0. if your running a symmetrical airfoil, don't forget to set the whole mess at 2 degrees positive to the center line of the airplane otherwise you will be running around with a nose high attitude all the time. THis is assuming your running the 2 degrees of washout. I have done it both ways.

Thanks guysvery helpful. Running semi-symmetrical airfoil so it looks like 0 to 1 degree wing incidence will be the ticket.
