Review: Good winch - This winch works very well for main sheet and jib sheet on the model sailboat. Review: Great for FIRST Robotics - Purchased for our local FIRST Robotics team (FRC Team 2980). The team reports that the servos are a perfect fit for their robotics use. This year's game involves significant vibration and impacts. The servos held up well to the punishment and function as designed. HiTec servos are durable and work flawlessly in the team's application. ## Features - Speed (4.8V/6.0V): 1.68/1.38 - Torque oz./in.

The team reports that the servos are a perfect fit for their robotics use. This year's game involves significant vibration and impacts. The servos held up well to the punishment and function as designed. HiTec servos are durable and work flawlessly in the team's application. ### ⭐⭐⭐⭐⭐ Sailwinch *by J***J on December 13, 2011* Great product for 1meter sailboats. 3.5 turns is just perfect for 10-15" of travel for sail movement. I ordered two but one would continue to search for end points. Sent it back and got a refund. I will order two more to have just in case, but will test each for proper operation before I save to my spare parts box. Keep in mind that a winch drive needs special set-up conditions to operate properly. You can find some options on the Internet. I use a three level thin plywood pancake with three standoffs at each corner that surrounds the drum in case the line comes off the drum. If the line screws up just let it out all the way and wind it back in. With the three layer pancake and no pulleys or rubber band you need to keep wind pressure on the sails whenever you let the sails in or out. ==---------== Top Ring of Drum [ ] ==---------== Center Ring of Drum [ ] ==---------== First Ring of Drum [ ] ====================== Top Level of Servo Mou Get thin plywood as close to the same thickness as the drum rings and about 1/2 inch past each sides of the drum. Cut a circle out of the center of each piece of plywood.(Three pieces) Use dowel or square spline as spacers in between the corners of the plywood spacers.(Twelve pieces) ## Frequently Bought Together - Hitec RCD 33785S HS-785HB 3.5 Turn Winch Servo - Tenergy 2 Pack NiMH Receiver RX Battery with Hitec Connectors 6V 2000mAh High Capacity Rechargeable Battery Pack for RC Airplanes/RC Aircrafts and More --- ## 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.us/products/9351275-33785s-hs-785hb-3-5-turn-winch-servo](https://www.desertcart.us/products/9351275-33785s-hs-785hb-3-5-turn-winch-servo) --- *Product available on Desertcart United States of America* *Store origin: US* *Last updated: 2026-07-31*
