I'd like to see an updated S-37 Superflanker, since the two models I have seem to be way out of date, such as lacking moving canards, engine flames, and a general flat texture apperance. I'd also like to request a black paintjob like on the MiG 31 Firefox in addition to the standard blue. Oddly enough, I've also seen it listed as the Su-47 on some sites.
