Xerun 1/8 4268SD G3 2400KV Brushless motor

Hobbywing XeRun 4268SD G3 2400kV is a no-compromise 1/8 on-road motor for those who want maximum power, brutal acceleration and silky-smooth throttle response – without sacrificing temperature or durability. It is developed for serious 1/8 GT and pan car racing and is optimized for the Hobbywing XeRun XR8 series of ESCs, where you get full utilization of “Pure Sensored” operation and Turbo Timing technology.

Pure Sensored operation – full control all the way through the throttle
This XeRun 4268SD G3 2400kV uses Hobbywing’s advanced “pure signal sensor mode” circuitry. When paired with a Hobbywing XeRun XR8 series ESC (e.g. XR8 Pro, XR8 Plus, etc.), the motor runs in pure sensored mode at all times.

This gives you:

• Extremely smooth and precise throttle response
• No cogging at low RPM
• Better control out of corners and in technical sections
• More predictable and stable handling – perfect for competitive use

The built-in intelligent IC allows the ESC to quickly and safely recognize the sensor unit, making setup and pairing hassle-free.

1/8 power system + Turbo Timing = massive top speed and punch
Together with Hobbywing XeRun XR8 series ESCs, this G3 motor can utilize Turbo Timing technology, which is known from the XR10 Pro series for 1/10 racing.

Benefits of Turbo Timing with the XR8 series:

• The motor delivers maximum power instantly
• Up to approx. 50% higher top speed compared to previous G2 series motors (with correct setup)
• Gives you a clear advantage on the straights and when accelerating out of corners

Note:

• When used with the XR8 Pro G2 ESC, the turbo angle can be set up to 48°.

—

Adjustable mechanical timing: fine-tune power to your track
The mechanical turbo timing on the XeRun 4268SD G3 can be precisely adjusted in both directions (CW/CCW) between 20–40°.

This means you can:

• Turn up power and RPM for large, fast tracks
• Turn down temperature and consumption for smaller, technical tracks
• Match the motor’s characteristics to your driving style and grip level

—

Improved efficiency – lower temperatures, more stable performance
Compared to the XERUN 4268/4274 G2, the G3 structure is optimized so efficiency is improved by 6% or more.

This provides:

• Lower motor temperatures under heavy load
• Reduced risk of thermal runaway
• More consistent performance throughout the entire heat or final

—

New Hall sensor technology – stable and fail-safe
The G3 series uses Hobbywing’s patented “error-free” Hall sensor technology with an independent, high-speed and high-precision encoder.

Advantages:

• Very clean and precise rotor position signal
• Effective isolation from electrical noise and external interference
• Stable sensored operation even under harsh conditions
• Maximum performance without dropouts in the sensor signal

Lightweight and strong 7075 aluminum construction
The motor housing is milled from a single piece of 7075 aluminum with precision CNC machining, providing high strength, good heat dissipation and low weight.

Design details:

• CNC stator housing without joints or visible screws on the outside
• Silicone dust ring around the sensor base for extra protection
• Front end bell with both M3 and M4 threaded holes – fits many different motor mounts
• U-shaped, 90° gold-plated copper terminals with low internal resistance – makes soldering easy and secure
• R-class insulation material (up to 240°C)
• Special adhesive with temperature tolerance up to 340°C
• Quality bearings from internationally recognized manufacturers, designed for high loads

—

Lightweight design – better weight distribution in the car
The 4268SD G3 series is optimized for low weight, making it easier to balance your 1/8 on-road car.
The low weight reduces unsprung mass and can improve both steering and traction.

(This 2400kV version weighs 276 g, see specifications below.)

—

Extremely smooth at low RPM
The motor is designed to minimize “low rpm no current torque” (cogging and small torque pulses).
The result is:

• Very smooth running at low speed
• Better control in the pit, slow sections and when precisely positioning the car
• More linear and predictable throttle response

—

Perfect for 1/8 GT and pan car on-road
The 4268 On-Road series is available in three KV variants: 2000KV, 2400KV and 2800KV, optimized for 1/8 pan car and GT.
This 2400kV version is a strong all-round choice for 1/8 on-road, where you want a combination of brutal acceleration and high top speed on 2–4S LiPo.
