This HITEC D-Series servo brings the surface servos in the 10mm class to a new level in control precision, freedom from play and longevity. With a powerful 6,0 kg @ 7.4V, the D145SW offers the highest resolution currently available on the market. The finest response and programming possibilities are realised thanks to 32-bit MCU and 12-bit ADC technology. Wide-Voltage servos can be operated directly on 2-cell lithium-based batteries (LiFe / LiIo / LiPo) with a nominal voltage of 4.8 - 8.4 V. The D145 SW surface servo is fully programmable and offers unparalleled durability thanks to its strong steel transmission and the two ball bearings on the output shaft. This is especially important when low play and high positioning precision are required. The long life is due to the uniquely designed steel transmission and the robust servo housing. The D-145SW surface servo is ideally suited for thin surface profiles in glider models and an application as a motor-gearbox combination for industrial applications. The included high strength wing mounting tray makes installation in the thinnest of wings really easy.
