The first step is the cockpit area. Attached the cannon muzzle assembled to the front fuselage. I don’t really know why they would not have molded this all in one piece.
The top fuselage consists of two parts that assemble quite well. No filling was required for this section.
There is a small part at the section of the cockpit tub, that varies depending on what version you are building. Most unusual for a Tamiya kit there was a bit of filling required on the one side. A quick bit of CA glue to fill the gap and some sanding solved it in no time. I then started on the cockpit tub by glue on the throttle and flight stick. Both sets of parts are now ready for some primer.
