This is perfect for my RC boat which needs a very low profile servo. The big surprise is this servo has rubber seals on the case and also the output shaft, making it somewhat water resistant. All I had to do was add some RTV where the servo lead wire exits the case to make this servo water resistant for my RC boat. ### ⭐⭐⭐⭐⭐ great product. needed a short servo to mount across from another, not enough room for two standard servos. *by on Reviewed in the United States December 2, 2011* Servo will be used on rudder for giant super sportster. I attached it to an Airtronics radio. will work fine. I needed a min. of 50 oz. of torque, this has 61 oz. ### ⭐⭐⭐⭐⭐ Five Stars *by on Reviewed in the United States December 29, 2016* Fits my application ## Frequently Bought Together - Hitec RCD 31077S HS-77BB Low Profile BB Servo - Hitec 32225S HS-225MG Mighty Mini Servo - Hitec 32645S HS-645MG High Torque 2BB Metal Gear Servo --- ## 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.za/products/12350734-31077s-hs-77bb-low-profile-bb-servo](https://www.desertcart.co.za/products/12350734-31077s-hs-77bb-low-profile-bb-servo) --- *Product available on Desertcart South Africa* *Store origin: ZA* *Last updated: 2026-07-07*
