    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!
