Hello all.
One more update.
This time the nose section.
Unfortunately, these segments are almost not shown in the instructions.
The front segment is closed with a glue tab at its front and the landing gear well should act as a positioner and a glue tab and a spacer for landing gear well edges to be parallel. After the closing of the front of the part, need to insert the engine inlet. Mounting the landing gear well took me many attempts untill I made a small paper strip to keep the edges of the landing gear well parallel. Then the well was mounted easily.
The second segment designed excessively cumbersome. The closing of the segment is done by the cover of the collimator/HUD, which has no former beside the top edge of the instrument panel. Then need to mount the well for the gun and then go the glue tabs to which the front segment should be connected. A lot of tries to fit these parts together, but I got it pretty well.
Over cumbersome design. I can think about other ways to design this part, but we got what we got.
