Hitec is pleased to introduce the new HS-755MG Giant Scale Servo Motor featuring metal gears and a single ball bearing. The 755 replaced the popular 700 and offers stronger torque for improved performance. The gears are stronger than the standard nylon and even after hundreds of thousands of cycles it will not show any signs of wear.
I was actually quite suprised at how well these servos perform. I combined four of these servos with four Actobotics Servoblocks, and they hold weight really well.
