They seemed happy with the performance.

I see. 1747 did have overheat issues as the result of mixing left and right motors on thier 2011 arm joint. They had locking pins in 1 of the two motors (it also happened wit 2 pinned motors). They ultimately resorted to attaching 2 victor fans to each motor to make the arm usable.

Sounds like a reasonable estimate...
