Futaba HPS-CT701 (30kg 0.07s/60°)

Very powerful and very fast programmable digital low-profile S.BUS2/S.BUS servo with AC motor, metal gears and output shaft mounted in two ball bearings with increased supply voltage for high-end 1:10 racing model cars - road and off-road. To ensure perfect cooling even under high load, the servo is housed in an all-metal box. For use with T7PX/T7PXR/T7XC/T10PX RC sets with R334SBS/R334SBS-E receivers, it is possible to switch them to SR mode and use the super fast transmission system T-FHSS SR (Super Response), or even faster F-4G telemetry system with T10PX transmitter and R404SBS/R404SBS-E receivers.

Using an AC motor brings:

• faster response compared to servos with a DC motor,
• longer motor life (up to five times compared to a DC motor),
• lower operating temperature and more economical operation due to the higher efficiency of the AC motor,
• higher efficiency and less production of waste heat also allow to increase thrust and speed of the servo without increasing its dimensions,
• interference caused by the sparking of the brushes on the commutator is eliminated,
• higher resistance to vibrations.

You can connect the HPS-CT701 to the S.BUS 2 (serial bus with bidirectional communication) or S.BUS (serial bus with unidirectional communication) outputs of the receivers for land models (Surface) or it can work as a classic servo connected to the channel (PWM) output of the receiver . The HPS-CT701 cannot be used with Futaba Air RC receivers.

With the help of the CIU-3 USB interface and the S-Link PC program or a Futaba transmitter equipped with the S.BUS servo setting function, you can program a whole range of servo parameters (speed, deviation size, neutral, overload protection, soft start, etc.). Setting the channel for operation on the S.BUS2/S.BUS bus and switching to SR mode is possible only with the help of the T7PX/T7PXR/T7XC/T10PX transmitter.

Increased supply voltage 6.0-7.4 V (nominal).

What is S.BUS2/S.BUS

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

Unlike classic RC kits, the S.BUS(2) system uses serial data communication to transmit control signals from the receiver to a servo, gyro or other device. This data contains commands like "move channel 3 servo to 15 degrees, move channel 5 servo 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. The servo identification code (ID) is used for this. You can find the ID on the sticker on the servo box.

The S.BUS2 servo can be connected to 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 - for some servos, the channel can only be set with the help of the transmitter).

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