Sir Spinalot = Overweight.

Your building a clone of Tornado Mer basically, so you might as well copy half the stats. Go 4 x S28-400 magmotors, this is on par with an ETEK, but it will all fit within 100mm tall. Drives, another pair of S28s will suffice here. Stack up on at least 8 x 24v 3600mAH battery packs.. Bring the size down to 800mm x 800mm x 120mm. Make the bar 1200+mm to get enough reach when attacking. Make the whole body out of 5mm titanium. Should be close to the weight limit. And a lot more realistic compared to you currently design.

Square = Overweight

4 x LEM130s for drive, plus a heavy hydraulic system that youve provided no real information for, where is your evidence that it has 9tonne at the tip? No information on batteries either.

I seem to be repeating myself here, but if you cannot back up your claims with some maths or information, dont make those claims. :wink:
