My advice would be to get an old cereal packet or similar thin cardboard, and try out various chassis ideas using card board and cellotape/ glue. Then when you're happy with the design, use the cardboard as a template to cut the 1mm hdpe. Saves wasting hdpe, and lets you play around with ideas and check if they fit in the cube. I probably wouldn't start cutting up the hdpe till you get the electronics to put in it, so you can check they fit properly. Just get prototyping ideas with cardboard first :)

If you want to work out the weight; 1mm hdpe weighs about 0.1g per square centimetre, so if you can roughly work out the area of your cardboard chassis in square centimeters, then multiply that by 0.1, you'll get an idea of what it'll weigh when built from hdpe.

Almost all my ants started as cardboard cut outs.. (chocolate bot still is :P)

Also, might have to get some 1mm hdpe; its about 20% lighter than the 1mm polycarbonate I use.. I want to try make a fleaweight cluster, so every gram is critical..

As long as it's under 350 square centimeters (say 300 to be on the safe side). That's equivalent to about a 17x17cm square of 1mm HDPE.. so you should be ok :P

I've currently got your kit doing onboard mixing. Need to know what channels you use though if you know them (Most people use Aileron and elevator for example)

here it is so far. it currently weighs 57 grams. all i need to add in now is the switch, the ramp and the roof pannel. i also need to lose about a millimetre off the top so it can run both ways up. there's still a way to go but for an hour's work i don't think it's bad for the first one.
