you know
in hovercraft the air has to be put under the body
and the propeller has to supply just as much air
as excapes here and there
but in helicopter all air escapes so the efficiency has to be much higher

maybe
i did the 6 fixed blades propeller
it gives so much air flow
but still nothing like helicopter isn't done
i bought some new bricks so the new hovercraft will probably appear
but now my pipeline is:
access boom ver03
helicopter ver 01 :)))
hovercraft ver03
of course my pipeline is not too stiff
so if i'll find some new ideas the pipeline will change
