As a low bot...ours was super compact, pretty climb and very fast when it worked and went all the way to top once too far.
Simple scissor with slots in top part instead of holes so top could center and pop off to winch up.
We used a winch connected to "collapsible coat hanger" part of the scissor and 2 Cims.
Had a wood box centering it.

Successful QF scale in SD week 1 at end of clip.
We were alliance 8 they were alliance 1
One of our original designs was something either inflatable as in OP or with a spring like a snake, we spent lots of time initially looking a different options. Glad inflatable worked that is cool. Love its simplicity.
