Thanks for all the help. I'm pretty sure I understand now.

maximum no-load speed is slower and the stall torque
(when motor speed is zero) is lower. The Victor speed controllers have
limitations which make trying to control the speed of motors
at low speeds difficult.

I forgot this was how Victors worked. Silly me.
