Check for assembly accuracy and degrease before assembly. Remove sprues with saw / cutter. Heat distorted parts under a light bulb (60W) or in a water bath and bend them. Work carefully! Glueing with 2K or superglue.
Separate the four tail units (1) from the bow and slightly buckle horizontally. Turn the rivet strap to the left. Glue the parts one after another with superglue into the slots on the bomb body and bend the upper corner of the baffle slightly to the right (for the spin when flying). Now remove the eight rivet straps (2) and glue them on the left and right at the bottom against the tail. Finally, drill two small holes (0.4mm) for the pins and then glue them in place.
