Here is a very reliable mech configuration I noticed none have posted. I put it together from a spare std 225 engine I had from another mech I modified. I also left a spare ton so you have a choice of either put in an extra laser, an extra Double Heat Sink or and extra ammo if you find you are very trigger happy and spend a lot of ammo. Standard engine is a must to last longer and speed is good enough, you can also use the extra ton to put in a std 235 engine if you feel the need for the extra speed. Firepower is good enough since the ultraAC fires fast enough to emulate an ac10 or ac15 and the range of the uAC5 is quite long to be used as a support sniper.
