Standard Size High-Torque Analog Servo TWSV4140 by Jazrider  [TWSV4140]

Compact high-torque standard servo

The TWSV4140 is a bulk-packaged, standard-size analog servo designed for scale radio-controlled models. It ships without mounting accessories, so separate mounting hardware and horns are required for installation. The unit suits typical control tasks such as steering, throttle and surface control where a compact higher-torque standard servo is needed.

The servo’s published response and torque figures from the original product data are: speed approximately 0.20 sec/60 at 4.8V and 0.16 sec/60 at 6.0V, torque 5.2 kg.cm (72 oz-in) at 4.8V and 6.5 kg.cm (90 oz-in) at 6.0V. Physical size is listed as 40 x 20 x 38 mm and weight is 43g including a 360mm cable. These values are useful when matching the servo to load requirements and available voltage in your radio system.

Installation notes: check horn spline compatibility with your control arms and choose mounting screws or brackets that fit the servo case dimensions. Because the servo is supplied without mounting hardware, plan for vibration isolation or added reinforcement on high-load linkages. Confirm receiver voltage and torque margin before final fitment to avoid overloading the servo in heavy-duty steering or actuator roles.

Tuning and use: in common RC setups this servo works well where a compact footprint is required but extra torque is desirable compared with basic low-torque units. Set endpoint and center trims in your transmitter and consider progressive throttle or steering curves for smoother motion under load.
