CM0821 – CEN BL-3658 3000KV SENSORLESS BRUSHLESS MOTOR – M-SPORT RALLY1
The CEN Racing CM0821 is the factory BL-3658 3000KV sensorless brushless motor used in the CEN 1/8 M-Sport Ford Rally1 platform. CEN identifies CM0821 as the original stock motor for the M-Sport , making the part number the definitive replacement reference for this application.
CONFIRMED PRODUCT DETAILS
- Manufacturer: CEN Racing
- Part number / SKU: CM0821 / CEGCM0821
- Motor designation: BL-3658
- Motor type: Sensorless brushless

FACTORY POWER-SYSTEM CONTEXT
CEN's M-Sport Rally1 RTR specifications identify the factory motor as a 3658 3000KV sensorless brushless motor. The same vehicle platform is documented with a 100A HobbyWing WP-MAX10-SCT-100A-3S RTR sensorless ESC and a recommended 2S–3S LiPo battery setup. Those vehicle-level specifications provide useful system context, but they should not be interpreted as a universal standalone rating for every CM0821 installation.
PACKAGE CONTENTS
- 1 × CEN Racing CM0821 BL-3658 3000KV sensorless brushless motor
CEN's public CM0821 listing does not state that a pinion gear, mounting screws, ESC, cooling fan, heatsink or other loose accessories are included, so those items are not assumed included.
INSTALLATION NOTES
- Confirm the target vehicle specifically calls for CM0821 before installation.
- Verify pinion bore, tooth count and gear pitch separately before transferring gearing.
- Set gear mesh with slight, even backlash across a full spur-gear rotation.
- Secure the motor so it cannot shift under load.
- Check the three motor phase leads and verify rotation direction before driving.
- Monitor motor and ESC temperature after changes to gearing, tire diameter or battery voltage.
FITMENT CAUTION
A 3000KV rating or a nominal 3658-size description alone does not guarantee interchangeability with another motor. Shaft dimensions, mounting pattern, can length, connector arrangement and thermal characteristics may differ. Use CM0821 / CEGCM0821 as the definitive fitment reference where this CEN motor is specified.
MANUFACTURER DATA NOT PUBLISHED
CEN's current standalone CM0821 retail page does not publish shaft diameter, shaft length, motor weight, pole count, winding resistance, no-load current, maximum current, maximum power, timing angle, rotor specification, bearing specification, connector size or standalone temperature limit. GASHEAD RC therefore does not estimate or borrow those values from unrelated 3658 motors.
