CQ0821 – CEN / SAVOX RTR-08 12KG STEERING SERVO – Q / MT SERIES
The CEN Racing CQ0821 is a factory Savox 12kg steering servo used in compatible CEN RTR applications. CEN's current product page names this servo RTR-08 (12KG), while an older Q-Series / MT-Series parts list labels CQ0821 as RTR-12 (12KG). Because the part number is the reliable identifier, GASHEAD RC uses CQ0821 as the primary fitment reference and notes the naming inconsistency rather than guessing which legacy label is definitive.
CONFIRMED PRODUCT DETAILS
- Manufacturer / brand: CEN Racing / Savox
- Part number / SKU: CQ0821
- Current CEN product-page designation: RTR-08 Servo
- Torque class: 12kg
- Horn spline: 25T
- At 4.8V: 10.0 kg-cm, 0.26 sec/60°
- At 6.0V: 12.0 kg-cm, 0.23 sec/60°
APPLICATION
CEN lists CQ0821 in its Q-Series / MT-Series electronics documentation and also specifies a 12kg Savox steering servo with the same published performance figures in its M-Sport Rally1 RTR platform. Vehicle fitment should still be confirmed by CQ0821 part number, servo dimensions, mounting pattern and required spline rather than assuming universal compatibility.
NAMING NOTE
CEN's current CQ0821 retail page calls this product Savox RTR-08 Servo (12KG). A separate CEN Q-Series / MT-Series parts list labels CQ0821 as Savox RTR-12 (12KG). GASHEAD RC does not alter or merge those model names into a new specification; the listing preserves the current retail designation and clearly documents the discrepancy.
INSTALLATION NOTES
- Center the servo electronically before installing the horn.
- Confirm the steering horn uses the correct 25T spline.
- Set steering endpoints so the servo does not force the steering system past its mechanical limits.
- Verify receiver/BEC output voltage is compatible with the servo.
- Check steering linkage for binding through the full suspension and steering range.
- After installation, verify failsafe behavior and steering direction before driving.
PACKAGE CONTENTS
1 × CEN / Savox CQ0821 12kg Servo. CEN's public CQ0821 listing does not provide a complete accessory inventory, so GASHEAD RC does not assume a servo horn, mounting screws, rubber grommets or extension lead are included unless present in the manufacturer package.
MANUFACTURER DATA NOT PUBLISHED
CEN's current CQ0821 product page does not publish case dimensions, servo weight, gear material, bearing count, motor type, deadband, pulse-width range, water-resistance rating, stall current or maximum operating voltage beyond the published 4.8V and 6.0V performance data. Those values are intentionally not estimated or invented.
Current product designation reviewed against CEN Racing's official CQ0821 listing. Performance data is corroborated by CEN's M-Sport Rally1 specifications. The differing RTR-08 / RTR-12 naming in CEN documentation is disclosed rather than resolved by assumption.
