I was browsing through a gallery I have of the Su-30. I found out that I have photos of the real Su-30 #302 similar to the diecast model I own. I posted below the photos of the Gaincorp 1:72 model and its "real thing".

The Sukhoi Su-30 (NATO reporting name: Flanker-C) is a twin-engine, two-seat supermaneuverable fighter aircraft developed by Russia's Sukhoi Aviation Corporation. It is a multirole fighter for all-weather, air-to-air and air-to-surface deep interdiction missions.

The Su-30 started out as an internal development project in the Sukhoi Su-27 family by Sukhoi. The design plan was revamped and the name was made official by the Russian Defense Ministry in 1996. Of the Flanker family, only the Su-27, Su-30, Su-34 and Su-35 have been ordered into serial production by the Defense Ministry. All the others, such as Su-37, were prototypes.

The Su-30 has two distinct version branches, manufactured by competing organizations: KnAAPO and the Irkut Corporation, both of which come under the Sukhoi group's umbrella. KnAAPO manufactures the Su-30MKK and the Su-30MK2, which were designed for and sold to China, and later Indonesia, Venezuela and Vietnam. Due to KnAAPO's involvement from the early stages of developing Su-35, these are basically a two-seat version of the mid-1990s Su-35. The Chinese chose an older but lighter radar so the canards could be omitted in return for increased payload. It is a dedicated strike fighter designed for long-range air-to-surface attack missions, similar to the American F-15E.
