The 25A ESC and 1212 4500KV motor in this combo come factory pre‑calibrated and matched.
They are ready to use immediately with no additional setup or parameter adjustment required – just power on and run.

IMPORTANT NOTE – When Replacing the Motor
If you use this 25A ESC with another brand or model of brushless motor, you must strictly follow the steps below. Failure to do so may result in incompatibility, improper drive, or even damage to the equipment.
① An AM32 programming card is required for parameter adjustment.
② Connect the ESC to the AM32 programming card.
③ Based on the specifications of the replacement motor (such as KV rating, pole count, internal resistance, etc.), reconfigure key parameters of the ESC including driving frequency, timing, start‑up power, and others.

Failure to reconfigure these parameters may cause the following issues:
1. Motor unable to start, stuttering, or cogging
2. ESC overheating or over‑current protection triggering
3. Permanent damage to the ESC or the replacement motor
