I have two mechs that are in need of some serious TLC.
The first is a Grasshopper, that had its head crushed by a Diglord. Note to self, NEVER stand next to and one elevation below a mech with a head capping kick. Second not to self, Edge is a glorious thing! That will need a new head, new cockpit, 2 sensors, 2 life support, LRM-5, and 9 points of armor.
240 minutes to replace the head, 2x260 minutes per sensor, 2x180 minutes per life support, 120 minutes each for the cockpit and LRM-5, then another 45 minutes to replace the head armor. A total of 1405 minutes or about 23.4 hours of work. This is exclusive of other armor damage which I don't have handy.
The second is a Centurion that was used as the prototype for Yen Lo Wang's 3051 upgrades. After some assorted other assorted damage, the gauss two crits, so the right arm and entire right torso went away. That beast needs 2x240 minutes to replace 2 locations, 3x90 minutes to replace the arm actuators, 120 minutes to install a new gauss, 300 minutes for the engine, 2x120 to replace the gauss bins, and 175 minutes to replace 35 points of armor. For a total of 26.4 hours of work.
Does this sound right?
