What is S.BUS?
Different from conventional radio control systems the
S.BUS system uses data communication to transmit control signals from a receiver to a servo, gyro, or other S.BUS compatible device. This data includes commands such as “move the channel 3 servo to 15
degrees, move the channel 5 servo to 30 degrees” to multiple devices. The S.BUS devices execute only those commands for their own set channel. For this reason, it can be used by connecting multiple servos to the same signal line.

[Operation by conventional radio control]
An S.BUS servo connected to a conventional receiver operates as a conventional servo.

  • Servo Torque(kg)(min. 0.01kg) 4.60

I bought 7. Of these 2 were defective.
If you take it to full travel on one side it stays there and then suddenly jumps to full deflection in the other direction. So these cannot be trusted and I cannot risk my plane. All 7 will go into the rubbish.
