Yes, its from FS.
The outline fits the inner measurements (the firewall) perfectly.
However, the ABS cowl is approx 3/32" thick
The Fiberglass replacement is approx 1/32" thick.
Therefore, the fuselage sides will be approx 1/8" higher than the cowl, all the way around.
You would either have to sand the fuselage sides really thin, or build up the cowl flange to match the same finished height.
If anyone wants a new cowl for either the King Kobra, or Komander, I am not going to use either one that I have.
