Key Features

• 40kg Torque at 7.4V — This servo delivers an extraordinary 40 kilograms of torque when powered by a 7.4V battery, providing the raw pulling power necessary to move control surfaces and steering mechanisms on large-scale vehicles with absolute authority and zero hesitation.
• Blazing-Fast 0.17 Second Response Time — Operating at 0.17 seconds per 60-degree rotation at 7.4V, this servo responds to your commands with millisecond precision, ensuring your RC vehicle reacts instantly to every input from your radio transmitter.
• High-Voltage Capability (6.0V to 7.4V) — Unlike servos locked into a single voltage, the SV0236MG+ thrives on high-voltage power sources, allowing you to maximise torque and speed by running 7.4V LiPo batteries while maintaining excellent performance even at 6.0V.
• All-Steel Metal Gear Train — The servo features a unique steel gear construction that ensures durability, longevity, and the ability to withstand extreme loads without stripping or wearing prematurely, making it ideal for competitive use and heavy-duty applications.
• Full Ball Bearing Support — With 2BB (double ball bearing) construction, this servo enjoys smooth, friction-free rotation that reduces wear, extends lifespan, and ensures consistent performance across thousands of operating cycles.
• Aluminium Heat Sink Case — The full aluminium case design isn't purely cosmetic; it actively dissipates heat generated during operation, keeping the servo cooler and allowing for smoother, more reliable performance during extended running sessions.
• Digital Technology with 12-Bit Resolution — The servo's advanced digital control system processes 4096 levels of resolution (12-bit), delivering incredibly smooth and precise movements that analogue servos simply cannot match.
• Soft Start Mode — The Plus model features an innovative Soft Start Mode that gradually ramps up power delivery, protecting your servo's internal components and your RC vehicle's driveline from sudden shock loads.
• Sanwa SSR Compatibility — This servo integrates seamlessly with Sanwa SSR radio systems, making it an excellent choice for competitive racers who use Sanwa equipment across their entire RC setup.
• 240 Hz Refresh Rate — The servo updates its position 240 times per second, ensuring remarkably responsive and smooth control that translates to more precise vehicle handling and faster lap times.
• 15-Tooth Spline Output — The servo features a standard 15-tooth spline output that accepts a wide variety of aftermarket servo horns and control arms, giving you flexibility in configuring your RC vehicle's steering and throttle systems.
• Heavy-Duty Servo Horns and Mounts — Bundled with robust servo horns and mounting hardware, this servo comes ready to install in your RC vehicle without requiring expensive additional components.

Technical Performance

The Savox SV0236MG+ represents a masterclass in servo engineering, combining brushed motor technology with advanced digital control circuitry to deliver performance that satisfies both recreational and competitive RC enthusiasts. At the heart of this servo lies a brushed 3-pole motor that, when powered by 7.4V lithium polymer batteries, generates 40kg of torque whilst maintaining a responsive 0.17-second cycle time. The servo's operating temperature range of -10°C to +50°C (-14°F to +122°F) means it performs reliably whether you're bashing on a cold UK winter's day or running in warmer summer conditions. The unique steel gear train ensures durability that synthetic or plastic alternatives simply cannot match, whilst the 2BB bearing system minimises friction losses, translating to more efficient power delivery. With dimensions of 65.8 x 30 x 57.4mm and a weight of 200 grams, this jumbo servo is appropriately sized for large-scale vehicles where standard servos would be underpowered. The servo's maximum operating travel spans approximately 130 degrees, with neutral position at 1500 microseconds and a pulse width range of 800 to 2200 microseconds for maximum flexibility in vehicle configuration. At 6.0V operation, the servo still delivers an impressive 30kg of torque with a 0.21-second response time, making it versatile enough to work with both 2S and 3S LiPo battery configurations. The no-load running current of 180mA at 7.4V ensures reasonable power consumption during normal operation, whilst the stall current of 5700mA at 7.4V indicates the servo will draw significant current when driving heavy loads, necessitating adequate power supply capacity.

Frequently Asked Questions

• Is the Savox SV0236MG+ suitable for my 1/5 scale RC car? — Absolutely. This servo is specifically engineered and recommended for 1/5 scale off-road vehicles and large-scale applications. Its 40kg torque output at 7.4V makes it ideal for steering heavy 1/5 scale cars, and the metal gear train can withstand the extreme loads these larger vehicles generate.
• What's the difference between the SV0236MG and SV0236MG+? — The Plus model (SV0236MG+) features two significant improvements: Soft Start Mode, which gradually ramps up power delivery to protect components, and Sanwa SSR compatibility for seamless integration with Sanwa radio systems. Both models share the same core specifications.
• What battery does this servo need? — The servo operates on 6.0V to 7.4V, making it compatible with 2S LiPo batteries (7.4V nominal) for maximum performance, or 2S LiFe batteries (6.6V nominal) for a slightly reduced but still excellent performance profile. For 6V operation, traditional NiMH battery packs work, though they cannot deliver the higher peak currents that 7.4V LiPo batteries provide.
• Can I use this servo in RC aircraft applications? — Yes, the manufacturer specifically lists large-scale aircraft as an ideal application. The servo's compact 65.8mm length and 200-gram weight make it suitable for control surface actuation on large RC aeroplanes, whilst the 40kg torque ensures positive control authority even in challenging flight conditions.
• Is this servo compatible with my RC receiver? — The servo features a standard JR connector and operates on standard servo control signals (800-2200 microsecond pulse width), making it compatible with virtually all modern RC receivers and radio systems from brands like Spektrum, Sanwa, Futaba, and others.
• How fast is the SV0236MG+ compared to other servos? — At 0.17 seconds per 60 degrees at 7.4V, this servo is extremely fast for a jumbo-sized model. Most standard-sized servos operate in the 0.15-0.20 second range, so the SV0236MG+ matches or exceeds the speed of much smaller servos whilst delivering vastly greater torque.
• Does this servo require special cooling? — The integrated aluminium heat sink case actively dissipates heat during operation, so external cooling is not necessary for normal use. However, during extended racing sessions or heavy continuous use, allowing brief cooling periods optimises performance and lifespan.
• What's the warranty on this servo? — Savox backs the SV0236MG+ with a full 1-year warranty from the date of purchase, covering manufacturing defects and component failures.
• Can I programme this servo? — The SV0236MG+ features digital control with standard servo programming capabilities through compatible programmers and radio systems. Check your receiver and transmitter manual for specific programming options available on your setup.
