Install Tips

• Heat Dissipation: When mounting the ESC to the frame, ensure it is positioned in an area with adequate airflow and is not smothered by excess wiring.

• Connector Security: Double-check that all bullet connectors and the signal lead are fully seated; loose connections can cause heat buildup or signal loss mid-flight.

• Direction Test: After installation, check the main motor rotation. If the motor spins the wrong way, swap any two of the three motor wires to reverse the direction.
