Using the Upgrade skin on the Aelahl has a few problems:
1-None of the patterns are available (Andromeda, Corvus, etc)
2-The weapon hardpoints are not properly colored. For example, using Romulan Type 3, the hardpoints in the center of the wings are colored red. In Upgrade, there are no colors. It's all the same color of green.
Comments
Unfortuantely the issue with the hardpoint mounts in the wing centers are still lacking a secondary color.

Pay attention to the highlighted areas in the upgrade skin and others and you will see the color problem.
