An ultra strong, high impact, composite material that is at the heart of our revolutionary new geartrain. Hitec’s new KARBONITE composite gear train has eliminated lash and slop forever. They are less likely to strip under the shock and loads that would usually break standard gears.

Found in all the "HD" (Heavy-Duty) and "HB" (Heavy-Duty Ball Bearing) servos. "Karbonite" gears are four times stronger than our standard nylons gears and offer virtually ZERO wear; even after 250,000 when tested! The result, you get better control with Hitec’s new KARBONITE gear technology.

The Hitec HS-56HB continues the Hitec tradition of affordable performance. Featuring our new revolutionary "Karbonite" gear train. Karbonite is four times stronger than our standard white nylon gears and even after hundreds of thousands of cycles it will not show any signs of wear. Combine that with precision components that have been engineered to provide long lasting trouble free service making the HS-56HB hard to beat!

Not only is it the perfect choice for any micro application from indoor R/C and hand launch gliders, to ultra small electric Park and Yard flyers, but it can handle the duties of larger electric 3D aerobatic aicraft as well. Mount it upright or flat; either mounting style is accepted with its unique case design. The new HS-56HB sets a new standard for heavy duty ultra micro servos.
