Technical Performance
The Savox SA-1230SG+ is engineered for exceptional performance with specifications that place it among the most capable servos available for large-scale RC applications. The coreless digital motor provides the foundation for superior speed and responsiveness, delivering 0.16 seconds per 60 degrees at 6.0V whilst maintaining an exceptional 36kg torque output, making it suitable for aircraft, 4WD rock crawlers, and monster trucks alike. The unique steel gear construction, combined with dual ball bearing support, ensures that this servo can handle continuous heavy loads without the premature wear associated with plastic gearing solutions. Weighing just 79.0 grams, this servo offers impressive strength-to-weight ratio, critical for aircraft applications where every gram affects performance.
The servo's compact dimensions of 40.3mm length x 20.2mm width x 44.9mm height (slightly taller case design than standard servos) provide a versatile form factor suitable for most mounting locations whilst the full aluminium case offers superior durability and thermal dissipation. Operating across a temperature range of -10°C to 50°C (-14°F to 122°F), this servo performs reliably in UK weather conditions and extreme environments. At 6.0V, the servo draws 250mA under no-load running conditions and up to 5300mA at stall current (locked position), with a minimal 5mA idle current for power-efficient operation. The servo features a 333 Hz refresh rate, 100-degree operating travel (1000-2000 microsecond pulse width), and maximum travel capability of approximately 130 degrees (900-2100 microsecond pulse width), providing flexibility in control range configuration. The digital control system accepts pulse width ranges from 800 to 2200 microseconds, with a neutral position at 1500 microseconds, ensuring broad compatibility with modern RC radio systems and receivers available throughout the UK market.

Frequently Asked Questions
- Is the Savox SA-1230SG+ suitable for rock crawling and monster truck applications? — Absolutely. This servo is specifically designed with rock crawlers and monster trucks in mind. The 36kg torque output at 6.0V provides the raw steering power needed for heavy steering loads on challenging terrain, whilst the durable steel gears ensure reliable operation through countless crawling sessions and aggressive driving.
- What is the difference between the SA-1230SG and SA-1230SG+? — The SA-1230SG+ (Plus model) features advanced Soft Start Mode technology and full compatibility with Sanwa SSR radio systems, offering more control options and smoother power delivery compared to the standard SA-1230SG model. The '+' designation indicates these modern enhancements for users seeking the latest servo technology.
- What voltage can this servo operate at? — The Savox SA-1230SG+ operates optimally at 6.0V, delivering 36kg torque and 0.16 second response time. It can also function at 4.8V, producing 30kg torque and 0.20 second response time, making it compatible with both 4-cell NiMH and 2S LiPo battery systems commonly used in UK RC vehicles.
- Is this servo compatible with my radio system? — Yes. The servo accepts standard pulse width modulation (PWM) signals from 800 to 2200 microseconds, making it compatible with virtually all modern RC radio systems available in the UK, including Sanwa SSR systems. The neutral position is set at 1500 microseconds, the standard used across the industry.
- What is the difference between coreless and slotted motors? — Coreless motors, like those used in the SA-1230SG+, eliminate the internal iron core found in slotted motors. This design reduces cogging, provides smoother and more consistent operation, generates less noise, and offers superior responsiveness compared to traditional slotted motor servos.
- How much current does this servo draw? — Under normal running conditions (no load), the servo draws 250mA at 6.0V and 180mA at 4.8V. When the servo is stalled (locked against an obstacle), it draws 5300mA at 6.0V and 4200mA at 4.8V. In idle mode, the servo draws minimal current at just 5mA, helping preserve battery life during normal operation.
- Can this servo be used in large-scale aircraft? — Yes. The SA-1230SG+ was specifically designed for large-scale aircraft applications including jet, 3D, and scale models. The excellent torque output, fast response time, and durable steel gears make it ideal for controlling large control surfaces on demanding aerobatic aircraft.
- What is included with this servo? — The servo comes complete with larger, longer servo horns featuring 25-tooth spline compatibility, aircraft rubber mounting hardware for vibration absorption, and a 200mm servo lead ready for connection to your receiver. This comprehensive package means you have everything needed for installation.
- How durable is this servo compared to plastic-geared alternatives? — The unique steel gear construction provides significantly superior durability compared to plastic-geared servos. Steel gears resist stripping under heavy loads, maintain their integrity through thousands of operating cycles, and are less susceptible to temperature-related degradation, making this servo a long-term investment in reliability.
- Is the SA-1230SG+ weatherproof? — Whilst the servo features a durable aluminium case, it is not sealed against water ingress like waterproof racing servos. For outdoor use, it performs well in typical UK weather conditions, but should be protected from direct water spray or submersion. The rubber mounting hardware helps absorb shock and vibration from rough terrain.
