Airfix is right about the colors, John. It was common for British bi-planes to feature counter shaded wings with the lower ones in lighter colors. Extra Dark Sea Grey/Dark Slate Grey tops, Dark Sea Gray/Ligh Slate Gray bottoms. The one I built was a pretty late production model assigned to the British Pacific Fleet in 1945, by which time the Walrus was being delivered in standard Extra Dark Sea Grey/Dark Slate Grey over Sky.

I agree, John. It always seemed a bit much for no apparent benefit.

John, @johnb, for a first bi-plane, and plane with rigging you sure picked a challenge. Looking great though, and interesting discussion of painting wings different colors. Whether the scheme worked or not it can definitely add more interest to the model. Are you going to go back and repaint the lower wing? Either way, it really is looking good.

Thanks Walt @luftwaffe-birdman,
Because some paint chipped off from the upper surface of the lower wing I was forced to repaint it anyway.
I added white in a 1:5 ratio to the camouflage used for the upper camouflage, so yes, they should appear slightly brighter, although on the pictures is does not really show.

@tcinla, thanks for sharing this information. That absolutely makes sense.
Maybe they dropped it because England is not having a lot of sunshine, therefore less shadow.
Hope to get the upperwing on this weekend.

Awesome John!

Finally it starts to look like a bi-plane.

Bottom part of the upperwing was applied.

Fitting and levelling went well, each wingtip has the same height to the surface.

All the wires were fed through as well.

After having the upperwing dried sufficiently, I attached the struts between the upper and lower wing, three on each side. Next I will need to get the rigging tight and glued to the lowwer section of the upper wing.

In the mean time I started to work on the engine, which is pretty detailed by itself.

The heat collector for the carburetor did lack openings for the exhaust, so I did some drilling to improve that part.

The engine was mainly painted charcoal black and dry brushed with a mixture of black/silver/gunmetal. Exhausts are painted with a mixture of rust/black.

You did a super job at drilling the intakes, and the spiderweb looks like it is getting closer to being sorted. Great progress @johnb!
