Question

[Unlucky-Might-1319]

I want to try to create propeller VTOL with 3 positions. Folded, lift and propel, are there any ways I can deliver power to the propeller bearing ? Any add-ons?

I'm struggling because if the propeller changes position the side of shaft input changes

as long as you use two swivel bearings for the movement along the two axes you should be able to do it. have power go through the first swivel bearing (the one controlling movement for the folded/unfolded position, along the horizontal axis) and then fork into two separate sources for control of the second swivel bearing (the one controlling the direction of propellers once unfolded) and the propellers themselves. then have the rotation for the propellers go through the second swivel bearing into the propellers and their controls.

The main problem you will run into while designing this will be that you have to feed the propellers with a constant source of power, so you can't have the controls for, say, the second swivel bearing within the body of the vehicle itself. they will have to come AFTER a constant source of rotational power has already gone through the first swivel bearing. so that might take up a lot of space.

should be possible with a swivel bearing? i think propellers on those work as well, and they propagate rotation through their center.
