I am also building a SPAD like Rick, but unlike Rick's, mine will be detailed - at least as detailed as I can do it. I believe this kit can be built into a very nice model, but it will take some work. Typical Roden, in other words.
I had started mine a couple of weeks ago, so I am well into it. I have just ordered a PE set from PART of Poland, which is for the SPAD VII, but there are many small fittings that can be used on the XIII. Hopefully it will arrive without delaying this build.
I wanted a chicken on my SPAD

so I have chosen to model a plane from SPA 48. Fortunately, FFSMC makes a decal sheet that accommodates this. I will depict Roques' plane pictured below:

I started with the engine. I will be closing up the engine so it won't be showing, but I built it without detailing just to see what it would look like.
I found that the base of the engine cylinders were too big to fit into the base at the engine block, so I remade the base of the cylinders. Hopefully, this does not make the cylinders too tall to fit under the cowling. If they are, some grinding will be happening.

The engine doesn't look too bad. I also remade some of the water / oil lines as some did not fit exactly where they should have.





I then started on the cockpit area.

Wood grain was done with the usual oil paints.



I added latches on the ammunition boxes, scratched the rudder bar pivot and put wire loops on the rudder bar. I didn't cut out the triangular openings above the rudder bar pivot. Just getting this made seemed like a miracle so I didn't push it.
To get the engine to fit all the down against the mounts, I had to remove the bottom oil line. This area will be covered by the bottom of the fuse. I also notched the wing spar.


More in the next update.
