How to apply for the Zest algorithm

lvtao · ‎2026-04-22

Hello,
I purchased the Zest development board kit. I have personally tried HSO and found it quite good. I heard that the Zest algorithm can achieve full torque output at zero speed. I am very interested in this. Could I apply for it personally?

probably not the kind of thing the community can help with.
