HS-7954SH High Torque HV Coreless Steel Gear Servo

Introducing the next generation Ultra performance servos from Hitec. The "Ultra Torque" HS-7954SH features our second generation "G2" programmable digital circuit, steel gear set, heatsink case, and ultra power coreless motor making it arguably one of the best R/C servos ever produced!

This new circuit has twice the resolution of our original circuit while adding programmable overload protection. The HS-7954SH has been designed for the most demanding hobby applications including the largest aircraft and monster trucks.

Featuring a titanic 402oz./in. of torque at 7.4 volts, all this power is harnessed by incorporating steel gears for great durability and two strong hardened steel gear pins and axial brass bushing mounted in the servo case.

We offer the HS-7954SH servo in 90° stock rotation or 180° modified rotation.
