Introducing the next generation Ultra performance servos from Hitec. The "Ultra Torque" HS-7940TH features our second generation "G2" programmable digital circuit, Hitec's exclusive Titanium gear set, Heatsink case, and ultra power coreless motor making it arguably THE best R/C servo ever produced! This new circuit has twice the resolution of our original circuit while adding programmable overload protection. The HS-7940TH has been designed for the most demanding hobby applications including the largest aircraft and monster trucks. The 222oz./in. of torque at 7.4 volts is impressive especially since the speed is a blazing .06 seconds to 60°. All this speed and power is harnessed by incorporating the industries first Titanium gears for incredible wear resistance and two strong hardened steel gear pins and axial brass bushing mounted in the servo case. We offer the HS-7940TH servo in several configurations, 90° stock rotation, 180° modified rotation, continuous rotation (potentiometer is left outside the servo case) and reverse rotation.
