When in doubt... build hell-for-stout!
We headed to Walmart today and I looked at foamboard... also looked at some 3/16" corrugated cardboard....
Ugh.
Way too flimsy.
<---- See here for details
I got home and had an epiphany: By the time I reinforce foamboard or cardboard... I might as well just make the body from plywood. I've got the wood working tools, so why not?
I re-ran the simulation using 1/4" plywood (I have some in the woodshed). It doesn't change stability, and since I'm using G motors they have enough thrust to still have a decent apogee.
My new mantra, per NAR: "Rocket weighs no more than 3.3 lbs (52.8 oz) (1.5 kg) all up."
Might have to use balsa or cardstock for the visually cool Epstein drive pieces parts.
