The UAV Servo 4509HV is a brushless, high-voltage digital servo built for unmanned aircraft control surfaces and mechanisms.
It is specified for an operating voltage of 8.4V and a torque rating of 45kg.
Brushless construction is the point of this range: there are no brushes to wear and no commutator to arc, so the servo holds its centring and its torque over a long service life instead of drifting after a few dozen flights.
It is intended for control surfaces and mechanisms on unmanned aircraft — aileron, elevator, rudder, flaps or payload actuation — where a standard servo would be out of its depth.
