The HS-5645MG represents the latest generation of Hitec servos. With a custom designed programmable digital circuit and our unique Alumite/ MP gear train technology the HS-5645MG has our famous un-breakable gear train. The powerful HS-5645MG is perfect for those applications that demand a high torque servo. Unbreakable MP Gear: The heart of our unbreakable geartrain is the MP Gear. The MP Gear is made utilizing a revolutionary production technique that injects a high impact plastic around a metal pinion gear to form an unbreakable first gear. By utilizing this gear Hitec has succesfully reduced the amount of drive train noise that is common in metal gear servos and at the same time added considerable strength to the geartrain. Specifications: Motor Type: 3 Pole Ferrite Bearing Type: Dual Ball Bearing Torque 4.8V/6.0V: 143/168 oz-in (10.3/12.1 kg-cm) Speed 4.8V/6.0V: 0.23/0.18 second Size: 1.6" x 0.8" x 1.5" (41mm x 20mm x 38mm) Weight: 2.11 oz (60 g)
This is a "standard" sized servo and would be considered a throttle servo for models like the HPI Baja and FG models.
