If you are interested in this mod, I would suggest using Clownagent's
Grav Armour mod instead. It includes my Jump Armour, but also a Grav Module which is just a flying backpack and is available before the Alien Alloys are researched. It also uses IMHO better sprites, more consistent with the Personal Armour design, but if you want the green version, use the Jump Armour graphics.
