I had a very difficult time with the Camel F1 set for Jan Olieslagers. The Belgian roundels were not printed on a white base, and the colors disappeared when applied to the PC10 wing surface (I ended up painting on my the roundels). The green tail flashes and cowling tulip triangles were the wrong size and did not fit the parts. The thistle emblem for the fuselage was a black outline printed on white paper, so had to be cut out with an x-acto knife, then was so delicate that it disintegrated. I ended up cutting a mask from kabuki tape and painted that as well.
I have another Spada set for Lafayette Escadrille Ni.17s, but I'm almost afraid to use them. Maybe Spada has since corrected the problems, and maybe I just got an early set, but my experience suggests caution.
Regards,
Bob
