The new ULTRA series digital servos with AC motors offer a number of revolutionary innovations. The use of a high-efficiency Neu / Castle Creations high-efficiency AC motor not only reduces current consumption versus digital servo-drives - thanks to Hitec's "Power Miser" technology, the current consumption is significantly lower than that of competing manufacturers of AC motors. We can show this on the example of current consumption when the servo is completely blocked - the Hitec AC servo is roughly a fifth of the current AC servo and even a tenth of the DC servo. Another new feature is the use of an electronics with a 12-bit control processor that allows extraordinarily accurate and fast control of ultra-high resolution servo motion - making full use of the 4096 steps the new Aurora 9X or Flash 7 offers! Another nice feature is that the servo will not depend on the supply voltage of the servos - whether you feed the servo from a NiMH five-cell or a LiPo twin-cell, the servo will have the same thrust (speed will be higher at higher voltages - DC "servos).
Another benefit of the Hitec AC servo is the regenerative braking - when the engine is stopped, the servo does not consume electricity but can return it to the receiver battery.
The servo electronics are programmable, they can be programmed using the DPC-10 or DPC-11 PC interfaces, along with a comfortable PC or PC utility. Separate HFP-30 programmer is ideal for setting up in field conditions. Programmable features:
Insertion of Hitec alternating servos
The regenerative braking may provide some special features when installing servos:
HSB-9380TH
Super strong digital servo with standard titanium-size AC motor and output shaft mounted in 2 ball bearings with increased supply voltage. Other axle gears are mounted in sliding bronze bushings to ensure long service life and accurate running. The Servo is especially suited for large helicopters and giant aircraft and other demanding applications with emphasis on high stroke, high resolution, precision and super fast response of the control electronics. Powerful AC motor with low current consumption ensures optimum operating conditions even at high load. The newly developed servo output shaft with a 25-teeth multi-pinch (inter alia, allows a more precise adjustment of the lever perpendicular to the longitudinal axis of the servo) and the new servo levers (not compatible with the existing Hitec servos).
Due to the increased supply voltage (up to 7.4V, 2s Li-poly / Li-Fe), it makes it very easy to implement the onboard electronics with 2.4GHz Maxima or Optima receivers when feeding Li-poly or Li-Fe double-cell without the need for additional stabilizers Or regulators.
