Hobbywing SCT Combo XR8 PRO G3 ESC & 3660SD 4200kv Motor (Versie 2025)

Introducing from Hobbywing the XERUN COMBO XR8 Pro G3 Speed Control & 3660SD 4200KV G3 Motor.

ESC Information

Compact And Capable!

The new XR8 Pro G3 ESC is 1.3mm shorter, and 5.3mm narrower compared to its predecessor. The overall footprint is reduced by approximately 15%. The all-new fully sensored XR8 PRO G3 ESC meets the needs of high-end 8th scale racing applications with its strong explosive power, ultra large output power(200a), while having excellent low-speed linearity.

A Maximum Output Current Of As High As 200A.

Dual Brake Mode.

The innovative closed-loop torque brake control mode is also known as the disc brake mode. It completely solves the problem of non-linear force caused by the influence of vehicle speed on traditional braking methods.

It enables linear output of braking force accurately, similar to the effect of real car disc brakes. The disc brake mode supports the adjustment of the curvature of the braking force and force distribution of the front and rear sections of the brakes. At the same time, the traditional braking mode is retained to take into account the driver’s control habits.

Excellent hardware design combined with innovative smart freewheeling technology enables the ESC to have higher drive efficiency and lower operating temperature. Compared with the XR8 Pro G2, the maximum temperature is reduced by approximately 15°C, and the ESC is stable and reliable.

Under heavy load conditions, the temperature of XR8 Pro G3 is lower than the XR8 Pro G2.

Compared with the XR8 Pro G2, the maximum temperature is reduced by approximately 15degC.

Frameless Fan, Efficient And Durable.

The frameless fan blade is designed with the use of specially formulated material to reduce the defective rate of the fan caused by impact from small stones, sand and other foreign objects.

Intelligent fan start/stop, noise reduction and power saving The fan of the ESC does not work when the temperature is low. The fan will automatically turn on when the temperature rises to the pre-set value. The intelligent start and stop function of the fan not only reduces noise, saves power, but also ensures that the ESC works in a good temperature range.

Advanced Boost & Turbo Timing Technology.

The XR8 Pro G3 ESC performs the best when it is paired with the recommended HOBBYWING motor. It inherits the same Turbo Timing technology used on the XR10 Pro series used in 1/10th On-Road and Off-Road competition.This ESC is able to support up to 48 degrees of Boost and Turbo Timing. There is a 50% increase in performance and is only recommended to pair with the new HOBBYWING 4268/4274 G3 motors.

Built-In Reverse Polarity Protection Circuit, Reinforced Protection.

The ESC is reverse polarity protected. In an event when a user makes a mistake by reversing the polarity, the ESC will not be broken.

Real-Time Data Recording Function.

Easy to obtain power running status. After connecting the OTA module box, turn on real-time data recording function to access the operating status.

Capacitor Thermal Protection.

Capacitor thermal protection is designed and implemented into the ESC and will effectively prevent capacitors from exploding and causing irreversible damage to the ESC due to overload.

Note: If the overheating protection of the ESC is off, and it is used on a flat road vehicle, please add a capacitor pack, otherwise the capacitor may be overheated and damaged!

Superior Dustproof Protection The ESC Is IP5X Rated.

It has a superior dustproof protection to protect the ESC in all types of environments. In addition, the ESC is equipped with a small protective cover for better fan protection.

Custom Ultra-Soft 11AWG Silicone Wire.

The ultra-soft 11AWG silicone wire is specially chosen for this product. The wire is ultra-flexible and low in resistance, making it the perfect combination to for your electronics.

Motor Information

Taking 3652-4500KV As An Example, The Maximum Power Increase Is About 5%.

Compared with the older XeRun 3652/3660 G2 motors, the motor output power is improved across the entire application load range

Turn On Turbo To Significantly Increase The Speed.

Compared with the XeRun 3652/3660 G2 motor, the maximum speed of the ESC is increased by 50%-100% when the 24° Turbo timing is turned on.

Safe And Reliable Motor Hall Sensor System.

The motor adopts the patented “error-free” Hall sensor system technology. The independent high-speed and high-precision encoder can always output pure rotor position signals, effectively avoiding sensor signal interference, so that the motor can continue to work stably in the sensed state.

High Reliability.

Explosion-proof rotor. Compared with the XeRun 3660 G2 motor, the XeRun 3660 G3 can reach an ultra-high speed of 75,000RPM (high temperature 140°C ), and its explosion-proof capability is improved by more than 15% , making it easy to cope with high-speed competition applications.

Excellent Dust Resistance.

The motor protection level is excellent for dust resistance, and can easily cope with various off-road dusty track environments.

Dual Hall Sensor Port Design For Easy Wiring.

The dual Hall output socket design at the rear of the motor meets various wiring requirements . Customized dust plugs are also provided to prevent sand from entering the sockets that are not in use temporarily.

Bi-Directional Mechanical Timing Angle Precise Adjustment.

• The motor mechanical timing angle can be adjusted in 20-40°bi-directional (CW/CCW).
• It is convenient for drivers to adjust the motor output power more accurately.
• Meet the power needs of various applications.
• Easy to disassemble and maintain.
• The motor adopts modular structure design.
• Easy to clean and maintain daily.
• Effectively extend the service life of the motor.
• Maintaining motor efficiency.
