Description

The Spektrum A6330 Digital HV Brushless High Torque High Speed Metal Gear servo delivers powerful, consistent control in a standard-size footprint. Designed for air applications, it combines a long-lasting brushless motor with a tightly meshed all-metal gear train and dual ball bearings for smooth, reliable operation. With 8.4V input it offers up to 248 oz-in (17.86 kg-cm) of torque and a rapid 0.10 sec/60° transit speed, supported by an aluminium centre case for enhanced heat dissipation.

Safety and setup refinements include soft start to help prevent damage during unintended initialisations, an integrated servo failsafe that holds the last known position if signal is lost (while power is maintained), and over-current/temperature protection. A helpful start tone indicates when the servo is ready. A long 18 in (457 mm) lead with a universal connector simplifies installation.

Features

  • Brushless motor for long-lasting durability with impressive power and speed
