ProTek RC have announced two powerful high-voltage, digital servos in the form of the 155T and 155S. They are usable for both 1/10th scale and 1/8th scale applications and feature precisely machined cases with deep, machined cuts in the lower cases that work as a heatsink to provide additional cooling. The 155T (0.08s/32.6kg-cm) and 155S (0.06s/26.6kg-cm) servos are ProTek’s first to feature a conformal coating – a thin layer of polymeric film that contours to the printed circuit board to protect against vibrations, moisture, dust, chemicals and extreme temperatures. Both servos operate from 4.8 to 7.4V, so they can easily handle high voltage input when conditions warrant maximum speed and torque. Other features include powerful coreless motors, metal gears and black receiver wires for that factory look.
