Futaba 107373-3 HPS-A703 Large Airplane Servos

This is a servo for large airplanes of the HPBLS series that achieves amazing torque and low power consumption.

The HPS series not only ensures surprising neutral accuracy and reliable torque, but also

Dispelling the relationship between speed power and power consumption, which has been considered to be a dichotomy until now,

Reliable power is achieved with low power consumption. The new HPS motor and high-frequency control have improved response.

・For large
airplanes, metal 1-3 gears
, high-strength metal terminal gears
, upper/middle/lower aluminum cases
, S.BUS system

- New control board

・High frequency control

・Speed: 0.12sec/60°(7.4V) / 0.13sec/60°(6.6V)
・Torque: 66.0kgf・cm(7.4V) / 61.0kgf・cm(6.6V)
・Dimensions/Weight: 40.5×21.0×39.4mm/82g

* The HPS-A703 requires a large instantaneous current in order to achieve both high output and responsiveness. In the case of intense acro flights, the power supply line may become unstable in rare cases, so when connecting one or more servos in the S.BUS system, please use a receiver capacitor (16V1800μF) for safety. Please refer to the instruction manual for connection.

* Batteries and BEC cannot be used.
