Rotating Reaction Wheel Axle

[SinisterDaeva]

I've seen a lot of people using rotating pieces, like 90 degree angle rotating wing-systems for VTOLs. I've been unable to figure it out so far on my own. How do you make a rotating axle?

I think most (all?) use Infernal Robotics (a very cool mod).

There are a few ways. The easiest is probably to use the infernal robotics mod which adds various electric hinges and similar into the game. It can be done with stock parts only however that normally requires more exotic designs with part clipping and separate ships for the wings/rotating bits. I'm no expert on stock bearings but some people have made very impressive stuff with them.
