The additional armour panel on top is designed as sacrificial armour. It is wholely additional with the original robot underneath in its normal guise, hence why it can be declared sacrificial and why you cannot label your normal armour as sacrificial. (I realise you are joking John W - just making things clear)

Storm II is normally running under weight hence the ability to add this piece.

THz managed some good hits down one side rail by the wheels and was on top of the fight at the start, we were coming back strongly with some good slams across the arena at the time we stuck THz on the wall.

As it happens it was subsequently discovered, I believe, that we had broken one of THzs motors and so would have been able to take more control of the fight even they had not got stuck and may have been able to make it more convincing.

As much as anything it was a tactic of letting THz lose some gas hitting the top before taking more risks in attacking back
