Assembly issues
Rear hull plate joins requiring filling.
I used Tenax-7R to "weld" the joins

Underside sponson gaps after fitting the rear hull.
These can be pulled closer together but take care not to distort the fenders in the process.

Trimming of the front hull to achieve a good fit.

Note: large sponson gap requiring filling

Rear hull issues:
1. Square hull cut-out with rounded corners on the intake
2. Top hatch different shape to hull cut-out
3. Rounded etched screen corners, should be square
4. Minor trimming needed to fit rear inspection hatch
5. Gap requiring filling after assembly each side
6. Only 7 bolts on exhaust shroud where there should be 8 for the STZ 1942
