PowerStar PM-2211 high-torque servo
PowerStar have introduced their new PM-2211 high-torque servo. It utilises a heatsink-design all-aluminium case, an all-metal geartrain as well as a powerful and efficient brushless motor. At 7.4V input the standard-size servo pulls up to 22kg-cm of torque at a speed of down to 0.11s with the servo being able to use up to 8.4V input for even greater performance. Included come a suitable aluminium servo arm and four aluminium servo mount bushings.
