4X3mm Metal Universal Joint For RC Cars Boats Planes with Grub Screws
This is a universal joint (u-joint) that allows to transfer rotational energy coming from a shaft into another shaft with an angle. What makes this coupling mechanism special is the fact that it allows for steeper and variable mounting angles compared to a fixed geared coupling. The joint comes with grub screws that can be fastened against the mounted shaft to secure.
