Hummingbird: Arms

The previously made S-Gundam Bst boosters had to be modified to work on the Zeta Plus. Basically for that, the fuel tanks in the bst body are dumped and in their place sit a a mechanical assembly and a connector piece for the arms. The upper arms have had their armor removed and the frame underneath (which was fairly simple before) has been visually enhanced to look more mechanical. Still lots to do. The boosters are still not quite finished as there is supposed to be a slight bend at the neck of the booster to make it stick outward a bit.
