This set is designed to be used on Su-34s and Su-35s and should fit either Trumpeter Hasegawa’s kits. The set consists of 18 resin parts which allows you to assemble a pair of the twin store carriers and provides the parts for either configuring the rails for either bombs or rocket launchers.
The parts are cast in grey resin which is of medium hardness which is easily cut with a razor saw or a sharp Xacto blade and sands easily. After washing the parts to remove any casting residue, I used a fine razor saw to separate the parts from the casting blocks. The instructions clearly show where to cut the parts off of the casting block and the resin spacers that between the side rail mounts and the center part of the upper pylons. I then used a 400-grit sanding stick to clean up the edges.
