News: My mate Vikki is now on-board as chief advisor, using her experience as an aircraft engineer. I am currently having a crash-course in space-frame design (HW corvis will deff. be a spaceframe, not monocoque)

Armour is looking like polycarbonate plates, each of which is attached to the frame via tempur-foam bushes and stiff springs and covered in 6+ layers of sheer-thickening-fluid-impregnated kevlar (not in a composite) No chance of being pierced, and the rest is all about shock absorbing.

Have contacted custom carbon-fibre parts manufacturer in Uk for advice on arbalest weapon: I can't make it myself: too much chance of air-bubbles in the composite (and those would explode under the pressure, making a crack in the weapon = fail )

Am now looking for a really basic FW on which to test armour and other ideas. No intention of winning anything. Just want a RC, moving, wheeled, box that's viable.
