The latest from Werner’s Wings provides an external auxiliary fuel tank for any 1/48 USMC AH-1W, AH-1Z, UH-1N, or UH-1Y kit. Floyd Werner provides great instructions showing exactly how to assemble the three parts along with color photos of various options for installation. A re-sealable zip lock bag holds the parts and the instructions.
Werner’s Wings has molded the external auxiliary fuel tank in grey resin with only a few minor bubbles. According to his website, the external auxiliary fuel tank is designed to be supplied on a resin sprue, but the kit as received has had the sprue already removed from the tank. The two other parts are supplied on a short resin sprue and will need to be detached with a photo-etch razor saw. I used a #73 drill bit to open up the mounting holes a bit and secured the parts with superglue. The connecting hoses are not supplied and will need to be scratch-built.
