Servo fade, weak holding power and the crowbar effect are just a few of the issues found with even the most expensive large scale surface servos, until today!Paul Beard, the person who brought 2.4GHz to the world of RC has done it again. The new Spektrum™ S9020 servo represents a new era in large scale servos and completely changes how 1/5-scale vehicles perform.The S9020 incorporates features not found in any servo on the market today. Starting with patent-pending Back EMF technology, drivers no longer have to be concerned with servo fade after just a few minutes of run time and inferior holding power. The S9020 HV servo maintains optimum performance levels throughout the entire run while providing speed and torque ratings that put it in the ranks of servos that cost twice as much.Dynamic breaking technology assures the vehicle maintains the heading demanded thanks to the servos brute level of holding power. An improved integrator design virtually eliminates the crowbar effect while keeping the servo temps low through even the most grueling of runs. ## Features - Improved integrator design eliminates crowbar effect and reduces heat build-up - Socket-head cap screws - HV for use with 2-cell Li-Po’s - Waterproof - Steering and throttle options available ## Images ![Spektrum S9020 Steering Digital HV Surface Servo (1/5 Scale) - Image 1](https://m.media-amazon.com/images/I/61TENNEPvdL.jpg) ![Spektrum S9020 Steering Digital HV Surface Servo (1/5 Scale) - Image 2](https://m.media-amazon.com/images/I/61SsoimgXcL.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ Spektrum S9020 In Redcat Rampage MT *by G***N on Reviewed in the United States on April 3, 2017* I installed this servo for the steering in my Redcat Rampage MT. I eliminated the 2 stock servos and installed 1 of these. I had to buy the Futaba aluminum mount for it to fit. This servo is great so far. Ran 2 tanks of gas after install. Will update after some time.Edit: This servo has been in my Rampage MT for many months now. It has been absolutely amazing! I can't recommend this servo any more! It has surpassed any of the other half dozen servos I tried before it! It is for sure waterproof! I have had this thing wet numerous times. If you are looking for a beast of s servo this is it!! ### ⭐⭐⭐⭐⭐ AHHHHHHHHH! *by T***G on Reviewed in the United States on September 21, 2018* BEAST MODE! ### ⭐⭐⭐⭐⭐ Great Servo for 1/5 Scale RC (Just Buy It) *by T***E on Reviewed in the United States on June 15, 2018* awesome servo works perfect for my Losi DBXL-E --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.co.th/products/25939102-spektrum-s9020-steering-digital-hv-surface-servo-1-5-scale](https://www.desertcart.co.th/products/25939102-spektrum-s9020-steering-digital-hv-surface-servo-1-5-scale) --- *Product available on Desertcart Thailand* *Store origin: TH* *Last updated: 2026-04-25*
