    I'd prefer new gearing on the AX12 to; Slow it down & Increase torque.
    Would happily accept a reduction in speed to 1/2 if the torque went up significantly.

    Interesting Re: New Robotis XL-320: Weaker but faster

    Humpf! I would love to see a version of the AX-12, but slower & stronger.
    Very few robots can use the max speed, but lots could use more torque, & especially so if compatible with the AX frames.

    If you don't mind voiding any possible warrantee, you could always add a heat sink to each AX-12 coxa servo, then if you still have issues, add some of those tiny fans jwatte found.
