Savox SA-1231SG Tall Digital "High Torque" Steel Gear Servo
Awesome Servo. I bought this for my 1/8 th scale and was looking for something that was cheap in price and high in torque and low in speed. I definitely got my money's worth with this servo. I have landed on my front wheels many times during hard crashes and yet this servo still works just as great as the day I first bought it. Crazy amount of torque and this is the only servo I found that had over 400+oz of torque and quick speed for an 1/8 th scale for under $150. If this ever takes a crap on me I will not hesitate to buy another. Perfect for a 1/8th scale servo. I highly recommend this servo.
