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

Powerful S.BUS2 Brushless Digital Servo with metal gear in LowProfile design. The servo is mainly used in RC cars as a fast steering servo for EP On- & OffRoad RC cars.

Advantages of brushless motor technology:

• 30% shorter reaction time
• Better acceleration
• More resistant to vibration and impact
• High efficiency, thus lower motor heating

• No carbon brush wear, thus 5-fold motor service life
• Special gear with maximum backlash freedom
• Cobalt Samarium Motor Magnets
• Highest resolution
• Same power consumption as conventional digital servos

Programmable through S.BUS2 technology! Of course, all S.BUS2 servos can be connected to conventional receivers with PWM modulation. Servos can be addressed in various ways:

1. via the S.BUS receiver
2. with the handy programmer SBC-1
3. via the PC-Link software with the USB adapter CIU-2
4. at the S.BUS connection of the transmitter

The following parameters can be configured:

• S.BUS channel assignment
• servo reversal
• Servotype (Normal / retractable)
• Soft start (On / Off)
• Mode selection in case of signal failure Hold or Free
• Soft servo run (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 (dead band)
• Servo travel adjustment left and right separated, approx. 50...175%
• starting force
• attenuation
• holding force
• ID storage
