The Tamiya F-16 series of kits are phenomenal renditions of the real airplane. There are multiple boxings. This particular set is designed to replicate the exhaust of the Pratt and Whitney F-100 Exhaust used on the Block 42 and Block 52 aircraft. They are externally very similar. The Block 42 has the -200 version and the Block 52 uses the -229.
Packaged in a sturdy cardboard box are two pieces of light grey resin inside of a resealable plastic sleeve. The two parts are perfectly cast with no blemishes anywhere. The detail on both pieces is remarkable.
The exhaust nozzle is a gem. It includes beautiful detail inside and out. Compared to the kit parts which only hints at the detail, the resin exhaust is perfect. There are beautiful exhaust petals and actuators.
The other piece is the afterburner liner. The kit liner is nothing more than a smooth surface. The real thing and the resin one has exquisite detail.
