Spektrum S7110 Servo Winch: 1/10 Rock Crawlers

The Spektrum S7110 Servo Winch (SPMSS7110) delivers reliable, consistent recovery performance for 1/10 scale rock crawlers and scalers. Its high-voltage digital design combines a brushless motor, metal gear train and ball bearing support for smooth operation and long-term durability. At 7.4V it produces up to 160 oz-in at 155RPM, with HV capability to 8.4V for as much as 180 oz-in.

A 25-tooth spline, universal connector and 360-degree continuous rotation make the S7110 straightforward to integrate into typical crawler setups. The low-profile case, 22 AWG lead and lightweight 57 g build help keep installations neat without adding unnecessary mass.
