Aires offers a myriad of after-market parts, this being a new offering. Designed for the Italeri kit I wanted to experiment a bit to see how the parts fit on the Hasegawa kit.
The first step is to remove the Aires parts from the part carrier. This is easy to do and quite safe as the parts are not delicate. I used a Xuron part nipper to remove the parts from the carrier, trim away any flash, and then also to cut the six exhaust ports into 3 units of two ports each. That division is required to get the Aires parts to drop into place on the Hasegawa kit. As you can see in the accompanying images, the parts fit nicely and without issue.
