I have downloaded a model from Sketchfab, it's a space ship. This ship was not rigged, so I've tried to rig it myself. But I have a problem, I would like to rotate the rotors of the aircraft, so I tried to rotate the bone that I attached to the rotor, but I found out that when I try to rotate the bone it rotates only by 360°.
Maybe do it through the N panel, choose Euler instead of Quaternion and enter the value you want on the rotation axis you want.
I guess if you do it manually Blender will try to find the shortest path from position A to B, whereas if you ask to rotate 500° in the N panel it will do it for real.
