Scale Capability

The SV1274MG is optimized for helicopter tail duty, where lightning-fast corrections and rock-solid holding power determine flight precision. HV capability keeps response consistent as the pack drains, while the steel gear train absorbs the repeated high-speed reversals tail servos see in aggressive flying.
