A4040 MT/HS Micro Metal Gear HV Servo

A4040 MT/HS Micro Metal Gear HV Servo Overview

The Spektrum™ A4040 digital micro, metal gear servo offers extraordinary performance for park flyer size (15-25 size) and specialty aircraft applications. High voltage capable, the A4040 can produce 7.0kg-cm (96 oz-in) of torque at 0.094 sec/60° speeds with 8.4V input. Its low-wear, metal gear drive train is powered by a coreless motor and bearing supported for smooth operation. The A4040 also features an aluminum center section case for efficient heat dissipation, plus low deadband and high resolution. Like all Spektrum servos, the A4040 delivers reliability, consistency and performance that are second to none.
