RC controls:
w - winch in
s - winch out
d - right
a - left
up - raise boom
down - lower boom
right/right - rotate grabbing part
1 - tension ropes
2 - untension ropes
space (it's in toggle, so you need to double tap it (this is to prevent cargo falling when you disconnect RC)) - toggle magnets
keep ropes slightly tensioned. If can't lift cargo, you probably need to tension them more. (ropes are additional support, actual accurate movement is done by robotic hinge)
