I made up cowl flaps from a Mountain Dew pop can. Also masked and painted the canopy, painted and weathered the resin wheels and assembled and painted the prop.
The landing gear has been installed with copper wire brake lines and the aluminum cowl flaps have been painted. I also made the tail wheel canvas boot from tissue paper and thinned white glue. I added a small piece of thin clear plastic sheet to the gun sight for the reflector plate.
