The metal gear D-645MW is part of Hitec’s D-Series dynamo servo line. All Hitec D-Series servos have been designed using their cutting edge, custom engineering. Combining industry leading high-resolution, state-of-the-art ultra-response technology with a 32-bit MCU, and a 12-bit ADC for unprecedented programmability and flexibility. These servos deliver significantly smoother movement. The speedy, powerful line operates on a wide 4.8 ~ 8.4 voltage range, allowing use with any common battery chemistry without the need for adapters or regulators. Featuring Hitec’s industry standard 25-tooth output spline with an M3 pan head with a phillips drive style, each D-Series servo brings monster performance never known before in the market.
