Thank you very much for the explanation, Legion! In fact, while watching the movie, I noticed that in the final fight with the "bad" robot, the Patlabor didn't fly... and I was like... oh oh, they are not exhausts..
Yes, Jeanma... but as it's my very first robot model of this kind, I want to go on the safe path. Maybe later I can add cockpit, pilot... the whole nine yards just like you did... well... not like you, but some.
Very good, let's continue.
Here are the unions for legs and pelvis.
And this is the pelvis, aong with other elements that form the waist.
And the belt-like piece.
But! I didn't like it! The gluing are too notorious. So, thanks to a paper modeling technique called "reprint", I managed to make another piece.
Next photo, to the right, the bad belt. To the left, the final version.
All the set together.
Then we put the pelvis to the legs.
