Futaba HPS-AA702 HV Brushless Servo S.Bus2 49kg 0.075s

The Futaba HPS-AA702 is a high-voltage standard aeroplane servo engineered for all‑purpose giant scale applications. It combines a custom high‑power brushless motor with an aluminium case and a stainless steel final gear for strength and precision. Compatible with PWM control as well as S.Bus and S.Bus2 systems, it is fully programmable and can be connected to a PC using the CIU‑2/‑3 USB adapter (sold separately). Transit speed is 0.075 sec/60° at 7.4V, with robust torque figures of 41.0 kgf/cm at 7.4V and 37.0 kgf/cm at 6.6V. Rated for DC 6.0–7.4V with an operating range of DC 4.8–8.4V.

Note: No dry battery or BEC use.
