This is the Spektrum S9020 1/5 Scale Digital HV Surface Servo, (Steering). No
Paul Beard, the person that brought 2.4GHz to the RC world has done it again. The Spektrum S9010 servo brings us into a new era of large scale servos and will completely change how 1/5 scale vehicles perform.
Spektrum’s S9010 servo incorporates features that aren’t found in any other servo on the market. Starting with patent-pending Back EMF technology, you’ll no longer be concerned with servo fade after just a few minutes of run time and inferior holding power. The S9010 HV servo maintains optimum performance levels throughout the entire run while providing torque and speed ratings that put it in the ranks of servos that cost almost twice as much.
An improved integrator design virtually eliminates the crowbar effect while keeping the servo temps low through even the most grueling of runs. Dynamic breaking technology assures the vehicle maintains the heading demanded thanks to the servos brute level of holding power. Using Back EMF technology, position lock exponentially improves the servos ability to keep its position while greatly increasing holding power. Additionally, the S9010 offers virtually zero servo fade, no matter how much is thrown at them.
Forget about doubling up on expensive and heavy dual servo mounts. The S9010 won’t fade under any condition.
