Finally sorted the drop tanks out. They've proved a bit more problematic than I'd hoped but got there in the end. I had to make four sway braces out of sheet metal these are a practical solution so not very scale. The amount of movement on the tank before these were installed was a little alarming [X(] They're in the scale positions except the forward one which is 5mm further forward due to the release mechanism being in the way........and on that subject they get released towards the front of the tank, the airflow then helps to slide the tank out of the rear retention slot.
