A7090 Brushless Low Profile Metal Gear High Voltage Servo (SPMSA7090)

This high-voltage, low-profile brushless metal-gear servo is designed for standard aircraft applications, delivering strong torque and fast response in a compact package. It runs on a 4.8–8.4V power range and can produce up to 18 kg-cm (250 oz-in) of torque with speeds as fast as 0.068 seconds per 60 degrees at 8.4V, making it a capable choice for control surfaces or other precise RC tasks.

Built with a durable brushless motor and a tightly meshed all-metal gear train, the servo uses dual bearings for smooth, consistent operation and long life. The design minimizes wear, maintains a tight deadband, and delivers precise holding power, with integrated overcurrent and temperature protection and a failsafe that holds the last position if the signal is lost while power remains. The low-profile body fits into shallow wing pockets and other compact spaces, and an operating frequency of 200–333 Hz helps ensure dependable performance across RC aircraft setups.
