Heng Long used to include the "Hatch Stop" but it was just a small loose piece of bent plastic and many of us thought it was just a piece of scrap and chucked it out

There is a problem with the thinking behind this piece, There is a cut out on the hatch and the cupola for the hatch stop but as it comes out of the box because the cupola is wrongly positioned the hatch stop does not fit,
WHY did nobody at Heng Long not notice a piece in the box did not fit anywhere on the model?
So much for quality control.
That is where the Forum comes in helping out with the proper location of the cupola
