I think the contrast was low in real life wasnt it?
The D is easier than the A conversion. The A version needs wing changes for the slats. Remember to cut out top and bottom wing surfaces to fit the larger slat and then glue the slat shut. I couldnt get it as neat as I wanted or get the gun covers on the top wing to disappear with sanding. The little extension at the rear of the wing that sticks out at the back of the MG cover needs to come off, but that leaves a recess on the flap that wouldnt have been there.
Have you test fitted the canopy yet? I must have had the front cowling a fraction too rear as the folding canopy section would not squeeze between the other 2 canopy sections.
