Feetech FT935BL 7.4V 35kg.cm 180° IP54 Brushless Servo

The Feetech FT935BL is a standard-size brushless servo with metal gears, an aluminium alloy case and IP54 protection against dust and water splashes. Rated at 35 kg.cm at 7.4 V, it suits large RC models, robots and outdoor actuators that run long duty cycles.

Key features

• 30 kg.cm stall and 7.5 kg.cm rated torque at 6 V, rising to 35 kg.cm at 7.4 V

• 0.111 s/60° (90 RPM) no-load speed

• 6–9 V input, so it runs straight from a 2S LiPo

• 180° working travel inside a 200° mechanical limit

• Aluminium horn on a 24T 5.75 mm spline, 350 mm lead
