A6320 Standard Digital High Voltage Brushless Aircraft Servo (SPMSA6320)

Spektrum high-voltage digital brushless aircraft servo delivers dependable power and digital precision for RC airplanes. It operates from 6.0 to 8.4 volts and provides about 270 oz-in of torque with a speed of roughly 0.10 seconds per 60° at 8.4V. A durable brushless motor, tightly meshed all-metal gears, and dual bearings ensure smooth, long-lasting operation. The aluminum center case helps dissipate heat, and a soft-start feature protects both servo and airframe during startup. Added protections include over-current and over-temperature safeguards, an initialization tone to signal readiness, and an integrated failsafe that holds the last known position if the control signal is lost while power remains.

Designed for performance in demanding RC aircraft such as 30–50cc size 3D aerobatics, giant-scale planes, and high-speed jets, this servo blends power, speed and value. Its heat-dissipating aluminum body, robust metal gear train, and brushless motor deliver precise, reliable control and lasting durability. Operating at an update frequency of 50–400 Hz and featuring soft-start, it minimizes stress on both the servo and airframe for consistent, responsive performance.
