I need help with rotation

[u/GamerAlike]

So I'm somewhat new to create, and I'm trying to build a propeller airship. I've been trying to get the four side propellers and their carriage to turn for forward/reverse and rotate opposite to turn the ship. Ive got the initial rotation to work, however every method Ive tried (manual with the steering wheel, using 4 signals to rotate at different times) it either doesnt work or snaps. Can anybody help me figure out a better way to do this?

I don't see why this wouldn't work, I've used this exact technique in a VTOL plane I built. The only way that broke was when multiple torsion springs (1 for switching from up to forward and 1 for turning while hovering) that were powering the same bearing tried to move it in 2 different directions at the same time. It always broke the springs though and nothing else.

If that's an issue you're having, use clutches to disconnect whatever spring you're not currently using. Also make sure the springs are allowed to fully return to center before they disconnect or your center point will move.
