Overview
The Maclan Racing DRK 4-Pole 6600KV Sensored Brushless Motor—also known as the Drag Race King (DRK)—is an extreme-power sensored brushless motor engineered specifically for no-prep and straight-line RC drag racing. Developed to pair with Maclan's proprietary DRK 4-Pole Unlock firmware, this motor delivers massive output while maintaining smooth throttle transitions through the DRK power stages.
Built on a robust 550-class platform, the DRK 6600KV is designed strictly for drag racing applications and is not intended for general on-road or off-road use. With a stainless-steel rotor wrap, adjustable timing, and an open end-cap design, it's purpose-built for the abuse of competitive drag racing.
Key Features
- 4-pole sensored brushless motor for extreme drag-racing performance
- Designed to pair with DRK 4-Pole Unlock firmware
- Smooth throttle transitions through DRK power stages
- 550-class can size (36 mm × 63 mm)
- Adjustable motor timing for fine-tuning
- Stainless-steel wrapped rotor for high-RPM stability
- Open end-cap for easy rear bearing access and maintenance
- 5mm motor shaft (optional 3.17mm shaft rotor available)
Performance Benefits
- Massive torque and RPM for short-burst drag passes
- Capable of up to 75,000 RPM with proper setup
- Predictable, smooth throttle response despite extreme output
- Quick maintenance access for repeated race-day runs
Usage Notes
- Best used with RC no-prep drag racing chassis (typically based on 1/10 scale platforms)
- Recommended Final Drive Ratio (FDR): ~7.8–8.3
- Do NOT exceed 75,000 RPM—rotor failure and ESC damage may result
- Under-gearing or over-gearing can cause excessive amperage and ESC failure
- Running this 4-pole motor in 2-pole mode may damage the ESC
- RC drag racing is highly abusive—expect shorter lifespan on drivetrain, ESC, motor, and batteries
