Servo Futaba S-U300 4.1kg 0.19s/60°

Product detailed description

Programmable digital standard S.BUS2/S.BUS servo with plastic gears for general use. Ideal for all types of aircraft models (up to the size of a 15-20cc combustion engine), cars and boats.

You can connect the S-U300 to the S.BUS 2 (serial bus with bidirectional communication) or S.BUS (serial bus with unidirectional communication) outputs of receivers or it can function as a classic servo connected to the channel (PWM) output of the receiver.

Using the CIU-3 USB interface and the S-Link PC program or a Futaba transmitter equipped with the S.BUS servo adjustment function, you can program a wide range of servo parameters (speed, deflection size, neutral, overload protection, soft start, etc.).

Standard supply voltage 4.8-6.0 V.

What is S.BUS2/S.BUS

• S.BUS – Futaba serial bus with one-way communication allowing control of servos, regulators, switches, gyroscopes and other compatible RC devices connected to a single S.BUS output port of the receiver.
• S.BUS2 – Futaba serial bus for two-way communication allowing (like S.BUS) control of servos, regulators, switches, gyroscopes and other compatible RC devices connected to a single S.BUS2 output/input port of the receiver. In addition, it allows you to connect telemetry sensors and transmit data from them via the receiver for display on the transmitter; Some S.BUS2 servos can send information about operating current, temperature or servo output lever angle to the transmitter.

Unlike classic RC kits, the S.BUS(2) system uses serial data communication to transmit control signals from the receiver to the servo, gyro or other device. This data includes commands such as "move servo channel 3 to 15 degrees, move servo channel 5 to 30 degrees" for multiple devices. S.BUS(2) devices only execute commands belonging to their own set channel. For this reason, it is possible to connect several servos to the same signal cable, while setting and controlling them individually as needed. This is done using the servo identification code (ID). The ID can be found on the sticker on the servo box.

The S.BUS2 servo can be connected to both the S.BUS2 and S.BUS ports of the receiver. Its function is determined by setting the channel in the servo memory (it is performed using the programming interface of the Futaba transmitter, the SBC-1 programmer or the CIU-3 USB interface with the S-Link PC program).

The S.BUS2 servo connected to the channel output of a classic receiver (PWM) works like a classic servo. Its movement is determined by the signal in the receiver channel to which it is connected. The setting of the programmable servo functions remains in effect.
