The yellow part is the 1mm polycarbonate chassis, and will be folded over when it’s finally built.
The green parts are 4mm polycarbonate. I decided to redesign after Fast Dalek beat Dynamite 9 times out of 10.
Major changes are lighter wheels (Pololu), a smaller receiver (Spektrum AR6110e), a more enclosing (and therefore stiffer) chassis, and larger front and back armour. I’ll probably retire the old aluminium forks in favour of acetate sheet.
