High-Torque Analog Servo for RC Models TWSV4140 by Jazrider  [TWSV4140]

Reliable standard-size servo with extra torque

The TWSV4140 is a standard-size analog servo offered in bulk packaging for use in scale radio-controlled models. It does not include mounting accessories or horns; purchase compatible hardware separately. The servo is geared toward steering, throttle and surface control roles where a compact standard servo with higher torque is preferred.

Manufacturer data list speed as roughly 0.20 sec/60 at 4.8V and 0.16 sec/60 at 6.0V, and torque as 5.2 kg.cm (72 oz-in) at 4.8V and 6.5 kg.cm (90 oz-in) at 6.0V. The advertised size is 40 x 20 x 38 mm and weight is 43g with a 360mm cable. Use these numbers when assessing compatibility with linkages and the vehicle's electrical system.

Fitment tips: confirm horn spline compatibility and select mounting screws or brackets that suit the case profile. As no mounting parts are included, fit vibration isolation or reinforce mounting points for heavy steering loads. Verify receiver voltage limits and torque safety margins before deployment.

Tuning guidance: set transmitter endpoints and center trims, and consider progressive curves for smoother responses under load when using this servo in steering or actuator applications.
