Hobbywing XeRun 4268SD G3 Sensored Brushless Motor 1900kv-2800kv for 1/8 RC Buggy & SCT

Hobbywing XeRun 4268SD G3 Sensored Brushless Motor

The XeRun 4268SD G3 is Hobbywing's competition-grade brushless motor built for 1/8 scale off-road buggy, short course truck, and touring car racing. ROAR approved and packed with patented technology, it delivers smooth power delivery and consistent performance run after run.

Key Features

• ROAR Approved – Competition legal for sanctioned racing events
• Full Sensored Mode – Built-in integrated circuit automatically identifies the sensor unit when paired with Hobbywing XR8 series ESCs — no manual setup needed
• Turbo Timing Technology – Supported when paired with XR8 series ESCs; up to 48° turbo when used with XR8 Pro G2 ESC
• Patented Staggered Pole Rotor – 4-pole-8-magnet design with low cogging for smooth power from a dead stop through full throttle
• Adjustable Mechanical Timing – 20–40° in both directions (CW/CCW) for flexible power tuning
• Advanced Hall Sensor System – Separate magnetic ring isolates the Hall sensor from external interference for clean, error-free signal
• 6% More Efficient than G2 – Optimized structure reduces heat buildup and lowers operating temperature
• IP5X Dustproof – Available on 4268-1900KV, 4268-2200KV, and 4274-2250KV versions only
• Lighter than Previous Generation – 1900KV is 20g lighter; 2200KV is 45g lighter than the equivalent G2 motor
• Premium Materials – Double insulated windings (240°C rated), high-intensity adhesive (340°C), NMB Japan bearings
• Gold-plated Solder Tabs – U-shaped/90° curved copper tabs with low internal resistance for easy wiring
• 7075 Aluminum CNC Stator Case – Single-piece precision machined; silicone O-ring seal at sensor port

Which KV Should You Choose?

• 1900KV – High torque, best for technical off-road tracks on 4-6S; IP5X dustproof
• 2200KV – All-rounder for 1/8 off-road buggy racing on 4S; IP5X dustproof
• 2000KV – On-road touring car setup on 4-6S; smooth mid-range power
• 2400KV – Faster top speed for on-road and smooth tracks on 3-4S
• 2800KV – Maximum speed for on-road racing on 2-4S

Compatible Applications

• 1/8 off-road buggy and truggy (1900KV / 2200KV)
• 1/8 short course truck (SCT)
• 1/8 touring car and on-road racing (2000KV / 2400KV / 2800KV)
• Best matched with Hobbywing XeRun XR8 Pro G3 ESC

What's Included

• Hobbywing XeRun 4268SD G3 brushless motor (per selected KV)
• Factory accessories

Important: Do not run the motor without load for extended periods. Stop use if motor shell temperature exceeds 100°C/212°F. Follow A-A, B-B, C-C wiring order when connecting to ESC. Never hit full throttle before installing the pinion.

The XeRun 4268SD G3 sensored brushless motor pairs with Hobbywing XR8 series ESCs for full sensored operation and smoother throttle control. Turbo Timing Technology is supported when paired with compatible Hobbywing XeRun XR8 series ESCs for maximum performance output. The adjustable mechanical timing ring allows CW/CCW adjustment from 20° to 40° for precise power tuning to match your track conditions. The optimized finned aluminum can design improves efficiency by 6% or more compared to the G2, reducing heat buildup during competition runs. The advanced Hall sensor system uses a separate magnetic ring to isolate the sensor from external interference, ensuring clean and accurate rotor position signals. IP5X dustproof protection is available on the 4268-1900KV, 4268-2200KV, and 4274-2250KV versions, minimising debris entering the motor in off-road conditions. The lightweight finned aluminum housing keeps the motor cool while maintaining a compact profile for easy installation in 1/8 scale chassis. The patented staggered pole rotor delivers low cogging effect for smooth, predictable power delivery from a dead stop through full throttle. Built from a single piece of 7075 aluminum CNC-machined stator case with gold-plated U-shaped solder tabs for A/B/C phase wiring and a silicone O-ring seal at the sensor port for long-term reliability. The 4268SD G3 is available in 1900KV, 2200KV, 2000KV, 2400KV, and 2800KV to cover both 1/8 off-road and on-road racing applications.
