Designed for durability and precision performance with features such as ball bearings and metal gears, the Graupner HVS 933 High-Voltage servo works universally across all model types but is ideally suited for small airplanes and helicopters. 

The HVS series are digital servos optimized for higher voltage input (up to 8.4V) with an aluminum heat sink for lower operating temperatures and longer run times. The HVS servos provide speed and holding power with low dead band technology for extra reliability and can be programmed to your unique specifications with our PC-based servo software.
