Hmm...I believe it's time I got back into checking, even though this is not my tournament (forgive me). So here I go...

Based on some calculations, I also fail to see how Metallic Doom can be 150kg...

The MatWeb material calculator tells me Metallic Doom's body armour is around 60kg...

Since I can't make too good of a calculation on hydraulic systems, my estimate is that the weapon armour and system would be around...20-25kg.

I don't know how many 'battlepacks' of A123 cells Lian is using :P but since he's got 11 packs, he'll outlast everybody, I think. I believe what Lian meant was 11 A123 cells, not packs. He would want 4-6 packs...let's go in-between with 5. A123 cells weigh around 70kg.

70g x 11 cells = 770g.

770g x 5 packs = 3850g, or 3.85kg.

Since LEM130s weigh 3.1kg and he uses two of them, that's around 10kg of power. The shuffling pads would be another 5-10kg, and miscellaneous bits (such as nuts, bolts, wiring, speed controllers, etc.) would be another 5-10kg.

60kg + 20-25kg + 10kg + 5-10kg + 5-10kg = 100-115kg. So yeah Lian, I think Paul is right.

Okay I'm done...
