Futaba BLS 571SV Brushless RC Car (S-Bus 2)

Powerful S.BUS2 brushless digital servo with metal gears in a low-profile design. The main application of the servo is primarily in the RC car sector as a fast steering servo for EP on-road and off-road RC cars.

Advantages of brushless motor technology:
• 30% shorter response time
• Better acceleration
• More resistant to vibrations and impacts
• High efficiency, resulting in lower motor heating
• No brush wear, leading to five times the motor lifespan
• Special gearbox with maximum play-free operation
• Cobalt-samarium motor magnets
• Highest resolution
• Same power consumption as conventional digital servos

Programmable via S.BUS2 technology! Of course, all S.BUS2 servos can be connected to conventional receivers with PWM modulation. The addressing of the servos can be done in various ways:

1. Via the S.BUS receiver
2. With the handy programmer SBC-1
3. Through the PC-Link software with the USB adapter CIU-2
4. At the S.BUS connection of the transmitter

The following parameters are configurable:
• S.BUS channel assignment
• Servo polarity
• Servo type (Normal / Retractable landing gear)
• Soft start (On / Off)
• Mode selection on signal loss Hold or Free
• Soft servo operation (On / Off)
• Servo position (Servo tester)
• Servo center adjustment +/- 300 µs (approx. 30 degrees)
• Servo speed, 0.39...9 seconds per 45 degrees
• Deadband setting
• Servo travel adjustment left and right separately, approx. 50...175%
• Start force
• Damping
• Holding force
• ID storage
