Between the reactor core and the side, there are two rectangles (vehicle chassis) packed with various details. Those provided in the kit are not accurates, too thick and too long.
I sanded them and recovered elements for details. The chassis is made with parts from the spare box (frames, strips...)

To complete the main nozzles (with the injection pipe on the side), again with spare parts (Bandai Macross vf -11 ankles) .

A tank wheel is set in the bottom of these nozzles to be more interesting.

At the base of bells, there are some sherman tank axles.

This part at the tail of the fuselage broke and had to be repaired

To keep all these resin parts together, they should be strengthened with metal rods : head, neck, engines, wings ...
