A7090 Brushless Low Profile Metal Gear HV Servo

A7090 Brushless Low Profile Metal Gear HV Servo Overview

The low profile Spektrum™ A7090 brushless digital metal gear servo offers superb performance at a great price for standard aircraft applications. High voltage capable, the A7090 can produce an impressive 18 kg-cm (250 oz-in) of torque at blazing fast 0.068 sec/60° speeds with 8.4V input. Its low-wear, metal gear drive train is powered by a durable, long-lasting brushless motor and is supported by dual ball bearings for smooth operation. It also features low deadband and precise holding power. Like all Spektrum servos, the A7090 delivers reliability, consistency and performance that are second to none.
