Feetech FT5330M 7.4V 35kg.cm 180° Steel Gear Digital Servo

The Feetech FT5330M is a standard-size PWM digital servo with a steel gear train and 35.5 kg.cm peak stall torque at 7.4 V. It suits large RC vehicles, heavy control surfaces, robot joints and mechanical actuators that need strong holding torque over a 180° throw.

Key features

• Steel gears on ball bearings inside a PA plus aluminium case

• No-load speed: 0.192 s/60° at 7.4 V

• Idle current: 6 mA at 7.4 V

• Signal: PWM, 500–2500 µs, 1500 µs neutral

• Travel: 180°

• Horn spline: 25T, 5.9 mm

The rated input tops out at 7.4 V, so run it from a regulated 6–7.4 V BEC rather than straight off a fully charged 2S LiPo (8.4 V). Budget around 4 A per servo for stall current when sizing that BEC.
