I was looking into making and angel themed character and read about the aerie windseeker in the chrome flesh book(page 208-209) but haven’t been able to find any stat blocks for it. Would to hear your opinions on functional cyber wings.
Functional cyberwings would be very difficult to do as actual wings. There's a reason why birds have hollow bones, you know. You could, perhaps, have a vectored thrust setup made to look like wings, like
Vulture in Spiderman: Homecoming, but I'd probably require an exotic vehicle skill to use the things.
Jet-packs and gliders? Those are easily done. In fact, I made a little
something like that back in 2011 for fun.
Actual, functional wings are more likely to be some kind of
Changeling quality or bioware mod, because mass is the big kicker here. Cyberware is heavier than normal humans, who are already heavier (and denser) than a bird of the same size would be. Your best bet for an 'angel' being able to actually fly would be to go the magic route, actually, and convince your DM to let you have some kind of modified version of the Levitate spell or similar that had visible wings as a part of the spell. Or, you know, something like
this.
