Futaba HPS-A703 For Airplanes (S.BUS)

Manufacturer: Futaba Corporation
Model: HPS-A703
New HPS motor and high frequency control for improved response in the HPS servo series for large aircraft.
The HPBLS series servos for large aircraft provide outstanding torque while maintaining low power consumption, making them perfect for powerful yet efficient performance. Meanwhile, the HPS series enhances this balance by combining exceptional neutral precision and consistent torque. It also removes the usual compromise between speed, power, and energy efficiency, so pilots can enjoy strong, stable output without wasting power. In addition, thanks to the newly developed HPS motor and advanced high-frequency control, the system responds more quickly and moves more smoothly, ensuring precise, linear control throughout every maneuver.
Features
This is a HPBLS series servo for large aircraft that achieves incredible torque and low power consumption . The HPS series not only ensures amazing neutral accuracy and reliable torque, We have eliminated the trade-off between speed and power consumption, Delivers reliable power with low power consumption. New HPS motor and high frequency control improve response.

*The HPS-A703 requires a large amount of current momentarily to achieve both high output and responsiveness. Intense acrobatic flight may occasionally cause the power line to become unstable. For safety, when connecting more than one servo with the S.BUS system, use a receiver capacitor (16V 1800 μF). For connection instructions, please refer to the instruction manual.
*Dry-cell batteries and BECs cannot be used.
