"Armored" cable?
Note further that home improvement store 'conduit-style' cable also will attach very well and securely to 'electrical box' enclosures (bare conduit will need 'fittings'). ...

Advice Needed for Control Algorithms of Vertical Landing Rockets
I'm guessing that, if you're not allowed a parachute, you're probably also not allowed free-spinning rotors - but a couple of them, contra-rotating, would provide wonderful drag....

"Armored" cable?
There exists steel-jacketed coax (use the shield as return), too:   https://ssicable.com/   Not cheap, and beastly to work with, but can tolerate just about anything....

Dipping into the well again....
So you don't want RC servo drive (Technically, PWM-driven potentiometer feedback gear motors), but you're okay with steppers.   The weight of your load is mostly irrelevant,...
