Im pretty sure it will be MDF, but best to ask john. weight in Blazer actually isnt much of a problem, at RAF Cosford last year it weighed 40kg. It only had it display armour on but the thicker stuff doesnt weigh much more. Blazers drive weighs about 11kg, i could make a Bosch drive for 15kg. Thinking about making the new Blazer as small as possible (probably would mean no weapon) just so we can have a fight.
