Separate voltage regulator IC for MCU (Micro Controller Unit), high capability of anti-interference. Low-voltage protection, block-rotation protection and signal lose protection, etc. All these functions can effectively prolong ESC service life. Programmable by Trx or by a Maytech programming card (optional). Program-Card has a simple and visual surface to conveniently change parameters at any time anywhere. Safe start-up. The motor won’t be started no matter which position the throttle stick is on when battery connected. Motor rotating direction can be changed by exchanging two of three wires from ESC or setting by the Program-Card. Progcard for programming HX ESCs:
