Jasta 300 Albatros D.III conversion

I've nearly finished assembling the 1/600th scale aircraft for play testing the Algy Flies Down Under scenarios, with only four Albatros D.III / D.Va models to get sorted. These are a bit more fiddly than you'd expect as I am adding twin radiators to the upper wing centre section, which were needed for cooling due to the high temperatures of the region. To do this I've sanded down the wing to remove the existing radiator, then glued small rectangles of plastic card in place before sanding them down to the right profile. It's all a bit of a faff but will be worth it in the end?
