As I mentioned on the Curtiss Group Build a long time ago, the cowling and accessory section in the Hobbycraft kit for Wright-powered machines is not round enough as it comes from the kit. I simply modified the kit parts and made a mold.
Resin cowlings and engine have been cast and are ready for painting/detailing/fitting.

In this instance I used the master cowling and accessory section for the build. This was actually a mistake on my part as I always save the masters for future moldmaking. However, these kits are pretty easy to come by so another master could always be made if needed. The airframe is nearly ready for primer:
