Assembly Phase

The lower hull runs across the opening circle thus making the turret wants to pop off 

The latch is also small so the locking isn't that good. On the other hand it's easier to pop the turret off for easier access 

For the fix. I had to cutout the part that runs across the opening hole that pushes up the turret 

Now the turrert sits properly and can rotate freely 

Trumpeter now seem to use a different design for turning the turret. The new design resulted in this tank having a big exposed turret ring that isn't present on the real tank. Perhaps this design is only for the particular model but nevertheless bad design by Trumpeter.
