Description
Extreme 8000KV sensorless brushless motor in a compact 22×36mm (370/2236) format. Built for maximum speed in lightweight 1/18 scale applications, especially on-road setups. Best run on 2S LiPo only with conservative gearing due to high RPM. Features a 2.0mm shaft and standard 370 mounting pattern.

Voltage & Performance
Recommended voltage:
No-load RPM:
Current & Power (typical)
Continuous current: ~10–12 A
Burst current: ~18–20 A
Estimated power: ~90–130 W
Efficiency: Lower than the 5000 KV version (runs hotter)
Intended Use
1/18 scale on-road
Micro touring cars
Speed-focused lightweight builds
Short gearing, small tyres, lots of airflow
⚠️ Important warnings (this motor is spicy 🌶️)
Do NOT run on 3S unless it’s basically unloaded (fans, props, or no drivetrain).
Gear very conservatively — tiny pinion, large spur.
Expect heat: add a heatsink or airflow if possible.
Shaft is 2 mm, not 3.17 mm (easy to strip pinions if forced).
Quick comparison (useful)
5000 KV: safer, torquier, better all-rounder
8000 KV: faster, hotter, shorter lifespan if pushed
