The ORCA Blitreme 3A V2 13.5T Sensored Brushless Motor is a competition-grade stock racing motor developed for precise throttle response, excellent efficiency and consistent performance in demanding on-road and off-road applications.

Its hand-wound 13.5-turn stator delivers smooth, controllable power across the RPM range. Sensored operation provides accurate rotor-position feedback to the ESC, resulting in smooth startup, predictable acceleration and precise throttle control through technical sections of the track.

The lightweight CNC-machined aluminium motor housing incorporates multiple cooling openings to promote airflow and help manage operating temperatures. Adjustable timing allows racers to tune the motor’s power delivery, RPM and efficiency to suit different vehicles, track conditions and racing classes.

The standard RT23HS12548 12.5mm rotor provides a competitive balance of torque and RPM. The motor is also compatible with selected approved optional ORCA rotors for further performance tuning where class regulations permit.

Built in the standard 540-size format, the Blitreme 3A is suitable for a wide range of 1/10 scale competition chassis. This EFRA-specification version is approved for regulated 13.5T stock-class competition and is also listed by ROAR.
