About this part

The Spektrum S9120BL 1/5 Digital Brushless High Speed High Torque Metal Gear Servo was developed to give 1/5 enthusiasts the huge torque and precision that can only come from brushless technology. Starting with a full aluminum case design with improved support for pins holding the gears, and an aluminum top plate with re-designed bearing house, the S9120 is tough. Brushless motor technology delivers more power than any previous Spektrum servo – the S9120 is rated at 1454 oz-in of torque, with a speed of 0.21 sec/60? at 8.4V. Additional improvements include a stealth black design and a thicker 18awg detachable wire. Plus, this servo is already race proven, having won the 2020 1/5 Worlds Buggy Class at So Cal Nitro.

Servo works good was hoping for a bit faster due to it being 8.4 volts but overall good

What reviewers say

Reviewers consistently rate this high-voltage brushless metal gear servo highly, with all five reviews at 5/5 from verified owners. Buyers say it delivers strong torque for 1/5 scale racing and works well overall. Two reviewers note the servo could be faster, one linking this to running on 8.4V. Two reviews also praise the seller's service and fast delivery, which are not comments on the servo itself. Overall feedback is positive, though the sample is small and speed is the only recurring criticism.

  • + Strong torque for 1/5 scale racing
  • + Works well overall
  • + Good seller service
  • + Fast delivery
  • − Could be faster
  • − Speed below expectations on 8.4V
