Hi Laser,
Dobby is correct. Whilst in the european theater, the U.S. adopted the french style cockade for use with any foreign built planes they used (French SPADs, Brit SE5s). The star insignia was used exclusively in the continental U.S. There were some excepetions - some U.S. built planes (fairly rare in the European theater) may have carried the star insignia - but for the planes represented in RoF, the cockade is the appropriate insignia.
*EDIT: and actually, as I read over the info at the link you provided, I'm gratified to see that it agrees with the assertions that Dobby and I have made. At the link you posted, please see the notation below the data about the star insignia. It's referencing specificially the period of time the USAS was in action in France.
Cheers M8!
