OK, basic problems involved in moving from FRW to the more complex stat system:

Weapon: Electric-powered Spinning Blade (Horizontal) - We need to know the shape and weight of the blade, what its made of plus the RPM. If you go to http://www.teamcosmos.com/ke/ke.shtml
http://www.teamcosmos.com/ke/ke.shtml you can enter the information you want, and also work out many many KJs it will produce, which tells us how powerful it is.

Armour: Titanium - We need to know the thickness of the Titanium in MMs

Sri-mech: Yes - The mechanism used is needed, such as a self righting bar like Hypnodisc.

Thats the basics anyway.
