Key Features

• Waterproof Case Design — The aluminium waterproof housing protects internal components from moisture, salt water, and snow, making this servo ideal for operation in wet conditions that would destroy standard servos. This feature is essential for RC boats, amphibious vehicles, and off-road RC cars UK used in challenging weather.
• Strong Metal Gear Train — The durable metal and plastic gear construction provides exceptional longevity and resistance to wear. The metal components ensure smooth operation under load whilst remaining affordable compared to full metal alternatives, striking the perfect balance between performance and value.
• Digital Technology — Unlike analogue servos, the digital circuitry enables faster response times, better holding torque, and enhanced resolution for more precise control inputs. The 240 Hz refresh rate ensures your commands are executed with minimal delay.
• Soft Start Mode — The Plus model's Soft Start Mode prevents abrupt servo movements during power-up, which protects your RC vehicle's drivetrain and improves overall system reliability. This feature is particularly valuable for delicate setups or competition vehicles.
• Sanwa SSR Compatibility — This servo works seamlessly with Sanwa SSR radio systems, offering RC enthusiasts flexibility in their transmitter choice and ensuring future compatibility as equipment is upgraded or replaced.
• Compact, Lightweight Design — At just 25 grams, the servo's diminutive footprint (29.5mm x 14mm x 32.5mm) fits perfectly into tight servo bays in 1/16 scale vehicles without adding unnecessary weight that would affect handling and performance.
• 25-Tooth Output Spline — The standard output gear spline ensures broad compatibility with aftermarket servo horns and control linkages, giving you maximum flexibility in customising your RC setup.
• Single Ball Bearing Construction — The single ball bearing provides smooth output shaft rotation and reliable centering, contributing to the servo's precise positioning and long operational life.

Technical Performance

The Savox SW0250MG+ demonstrates exceptional engineering with specifications that place it at the forefront of micro servo technology. Operating from 4.8 volts to 6 volts, this servo achieves its maximum torque rating of 5.0kg (69.4 ounces-in) at 6 volts, with an impressive response speed of 0.11 seconds per 60 degrees at the same voltage. The servo's brushed motor, combined with the digital control circuit, ensures rapid acceleration and precise holding, whilst the 240 Hz refresh rate guarantees responsive handling that serious RC car UK drivers demand. At 4.8 volts, the servo still delivers respectable 3.5kg torque and 0.14-second speed, making it viable across a range of battery configurations. The servo operates within a temperature range of -10°C to 50°C, maintaining reliable performance in harsh weather conditions that would challenge inferior designs. The 100mA running current at 6 volts represents efficient power consumption for a servo of this capability, whilst the 1250mA stall current indicates powerful holding strength when locked. The pulse width range of 800 to 2200 microseconds provides approximately 130 degrees of maximum travel, with standard operating travel of 100 degrees. The waterproof case design, crafted from durable aluminium, combines lightweight construction with environmental protection that traditional plastic cases simply cannot match. The metal and plastic hybrid gear train offers the durability needed for regular use without the weight and cost penalty of full metal construction.

Frequently Asked Questions

• Is the Savox SW0250MG+ waterproof servo suitable for Traxxas 1/16 scale vehicles? — Yes, the Savox SW0250MG+ is specifically engineered as an excellent replacement for standard servos in Traxxas 1/16 scale vehicles including the Slash, E-Revo VXL, and similar models. The compact dimensions and standard JR connector ensure perfect compatibility with these popular ready to run RC cars UK.
• What voltage should I run this servo at for maximum performance? — The servo performs optimally at 6 volts, where it delivers its full 5kg torque rating and fastest 0.11-second response speed. However, it operates reliably at 4.8 volts with reduced specifications (3.5kg torque, 0.14-second speed), giving you flexibility based on your battery and receiver setup.
• Can this waterproof servo handle salt water use? — The waterproof aluminium case design protects against freshwater, snow, and moisture in wet conditions. However, for regular salt water use (such as RC boats in coastal environments), we recommend rinsing the servo thoroughly with fresh water after each use and storing it in a dry location to extend service life.
• What is the difference between the SW0250MG and SW0250MG+ models? — The Plus model (SW0250MG+) features Soft Start Mode, which prevents sudden servo movements during power-up and protects your drivetrain. It also includes Sanwa SSR compatibility for enhanced transmitter flexibility. The original SW0250MG is discontinued, so the Plus model is the current and recommended choice.
• Is this servo fast enough for competitive RC car racing? — The 0.11-second response time is competitive for a micro servo in this category and suitable for serious hobby-level racing. However, if you're competing at the highest levels, compare this spec against dedicated race servos for your specific vehicle class.
• Does this servo include servo horns and extensions? — The servo includes a standard horn with the 25-tooth spline pattern. You may need to purchase additional horns or extensions separately if your specific vehicle setup requires different configurations.
• What is the connector type on this servo? — The servo features a standard JR connector (sometimes called a universal connector) which is compatible with virtually all RC receivers and radio systems currently in use, including Spektrum, Futaba, and Sanwa equipment.
• How long is the servo lead cable? — The servo includes a 200mm (approximately 8 inches) servo lead, which is suitable for most standard servo installations. For longer cable runs, you can purchase servo extension cables separately.
• What operating temperature range can this servo tolerate? — The servo operates reliably in temperatures from -10°C to 50°C, making it suitable for winter RC driving, summer heat, and virtually all UK weather conditions. Extreme temperatures outside this range may affect performance or cause damage.
• Is the servo gear train metal or plastic? — The servo features a hybrid metal and plastic gear train, combining the durability and efficiency of metal gears with the smooth operation and noise reduction of plastic components, representing an optimal balance for this servo class.
