FYI, folks. It did matter in this case. The ESC would not run the 21.5T motor. It cooked the ESC. I tried it on two of the same kind TBLE-02. I believe it can't handle the timing properly and there are no timing adjustments for it. Luckly the second one wasn't damaged. I went with a matching ESC from the same manufacturer of the motor. Works great.

Hope this helps someone. Take care.
