    I read someplace on this site that in order to keep speed and torque optimal, we want to keep the CTC Lever at a 90º angle to the control rod when at the zero point.

    Is there a disadvantage to tilting the motor like in this picture?

    I searched the forum and didn't see anyone else ask this and I'm pretty sure I'm not clever enough to think of this on my own so I can only assume I suck at searching. :(

    I'm designing a shoulder mount 2dof platform.

    The motor angle won't matter if that suits your design.

    With respect to a lever maximum torque effectiveness is at 90 degrees through a max range of about 38-40 degrees, after that effective torque utilisation drops off rapidly.

    Well good thing I didn't spend a lot of time on my 'breakthrough' then.

    Thanks!

    I don't see any issue with it. As long as you calibrate the center point at 90 degrees to the base of the rig, there will be no issue with having the motor body in a different orientation.
