Quickboost is known for its resin upgrade accessories for 1/72, 1/48 and 1/32 scale aircraft. The resin reproduces details often not available in plastic model kits. This exhaust stack does a great job of replacing the kit’s plastic equivalent and literally just falls into place with some sanding.
With the release of Arma’s new 1/48 P-39 aircraft series, this accessory (designed for the Hasegawa P-39s) makes the exhaust stack pop even more with its detail. While researching exhausts on P-39 aircraft, different model numbers had different exhausts (most Airacobras had six per side, the P-39F and P-400 had twelve per side), so be sure to research the particular aircraft being modeled as Quickboost also makes other P-39 exhausts for the P-39, P-39Q/N, and P-400 Airacobras (along with other detail sets, including engines, flaps, gun barrels, etc).
