Henry,
There are no limits what you can use for the more complex
turret and upper hull shapes. For the tool box on the PzIV, T-12, I
formed the rear curve using 2 sheets of 1/16" balsa with a thin piece
of aluminum roof flashing sandwiched inside. I then coated the outside
with epoxy resin. Took plenty of paintball hits,never cracked. I've
also used scrap pieces of vinyl siding for other curved areas.These
are all nice,light materials with excellent strength versus
paintballs. Just make some sturdy ribs to attach them to and making a
complex shape is not too difficult. Hope this helped some.
Regarding the overall lightness of a tank, the bulk of the
weight comes from the types of motors you will be using and the track
system that you choose.
