@IntoTheDesignatedGridZone I did
And Ik about the blue prints
@KPLBall also
maybe check wiki pages for
- "List of military aircraft of the United States"
and also...
consider going to secretprojects.co.uk - alot of real but unbuilt aircraft are posted there, however you may want to find blueprints too so casually check it out. don't ask for Curtiss XP-18 and -19 blueprints. They're non-existent.
@Alternation yes
Mobile will have 8 tho
@IntoTheDesignatedGridZone premiums
