    hello everyone.
    I was trying to upgrade my 2dof plus TL sim rig and came across the Sfu. Does anyone know what engine specifications are needed? watts, rpm, and the coupling with the reducer they have, I am referring to the distance between holes that it must have. I calculate standardized measurements and similar to an nrv40 gearbox.

    Great info, thanks. Shaft diameter and lenght are important? Or I can work it out with some CNC coupling?

    standard motors in this size have 2 sizes of shafts - 9 or 11 mm, you can use CNC-coupling or buy with SFU units size what you need
