Hitec D930SW, D954SW & D955TW digital servos

Hitec have expanded their range of premium-class D-series servos with three new high speed and high torque variants. The D930SW (0.07s/13.0kg-cm), D954SW (0.12s/29kg-cm) and D955TW (0.12s/20kg-cm) are powered by a 32-bit microcontroller unit with a 12-bit analog to digital converter for rapid, high resolution response. Coreless metal brush motors, long-life potentiometers as well as dual ball bearings make for high durability while nylon reinforced plastic upper and lower cases in combination with aluminium heatsink middle sections make for low weights as well as exceptional dust and splash water resistance. All servos are widely programmable, they are high-voltage compatible and the SW types feature precision-cut steel gears while the TW variant comes with a lightweight yet durable titanium gear train.
