Need Help completing Dark Wolf

[Failed_Hero]

Ok I have scoped together a mesh for my Dark Wolf Character it is almost perfect.  However I have put the under arm wings from Falcon onto the mesh (because dark wolf suit uses a wing/cape to help him glide).  I am having to issues:

1. the wings turn too far under when in flight making them look terrible.

And

2. I have not idea how to get the wings to do the "appear/disappear" thing like on the Tommy_boys's batman_beyond_t mesh.  Whoever could help me complete this mesh will have my eternal gratitude.

Thanks any help is apprecaited
