I took the old "Predator" build and applied some new tech to it: Upgraded engine from STD to LE, which let me: Upgrade PPCs to HPPCs Also bumped MLs to ERMLs Took out AMS and added more heat sinks This mech actually comes in at 0.06 tons underweight and it has full armor, but I kind of ran out of critical slots. It's got less DHS than the original (due to the original having a few more slots with the STD engine). I went with ERMLs and regular LLs because I felt the MLs needed the range boost more. I went into both the Firepower and Operations tree and got everything related to cooling in order to make this even work.
I would take out the two ER MED in the arms and replace it with a targeting computer MKII and also move the heatsink in the left arm to the right arm.
