So I want a warhawk for my clan unit. whats the diffrence between the stock one, and the one from the Clan omnimech parts?
If you mean OP-084, it's the torso of the reseen Warhawk, as far as I can tell- it's not the original sculpt, but I don't see any changes to it compared to my reseen Warhawk I have here to say it's modified in any way.
Some of the Omnis (the Vulture, for example) have alternate torsos to accept different arms added on, instead of having pegs for socket-style arms to attach to they have sockets for peg-arms to attach. But this has the same sockets that the Warhawks I've built had, so I think this is just a stock reseen torso.
