Here's a closeup of the engine....I see I already lost a valve spring
It's difficult to photograph, but one thing I experimented with on this build was using a Tamyia weathering kit to "silver" the invisible thread rigging. You might be able to see the effect a bit better in the photo below:
There are two lines running across the Tamiya box. The lower one was silvered using the sponge tip that comes with the weathering kit. This image is from the Eduard 1/48 D.V Weekend Edition kit I'm working on. I didn't think of trying this until I had already finished rigging the 1/32 Albatros, and I found it a bit difficult to manuever the brush, plus I didn't want powder residue to mess up the finish. So, I'm trying it on the D.V before installing the top wing. This way I can be sure to get the effect on all sides of the thread.
I wish I could photograph this better, because when the light is right it looks quite convincing.
I made a simple little mask to help keep the powder residue off the model:
