  • Cast Aluminium housing
  • Brushless motor - No brushes to get worn
  • Short shaft version - For AR36, Thompson, AUG & AK AEGs

If you're looking for an upgraded AEG motor with the best price-to-performance ratio, you're looking for the Warhead Industries Base Brushless Motor! This brushless motor was conceived as a more affordable alternative to the legendary Warhead CNC Black Brushless Motor, boasting similar performance at an unbeatable price point. This, the short shaft variant, is designed for AR36, Thompson, AUG and AK AEGs. 

Like the Warhead CNC Black motor used in Bolster Armouries builds, the Base boasts an ESC (electronic speed control) module which protects your battery, provides low-voltage cutoff and regulates speed to keep the immense power of the Base under control. The primary difference between the Base and the CNC Black is that the base uses a cast aluminium housing instead of a CNC machined one and the stator is wound via machines while the CNC Black is hand-wound. 

The advantages of running a brushless motor are numerous, the most important of which is a far higher torque to weight ratio than conventional motors. The lack of brushes means there is less to go wrong and the motor is far quieter when running, guaranteeing a longer lifespan of smooth running performance. That said, these motors are intended for highly upgraded setups so we only recommend them for those who are confident working on AEG internals. If your custom-built beast needs an equally beastly motor to drive it, the Warhead Base Brushless Motor; Short Shaft is one of the best choices out there!

  • High speed gear set
  • Fits most Airsoft gearboxes
  • 13:1 Ratio - Great for high ROF builds

Building a speed demon of an AEG? You will need high speed gears to get the most out of it! The CNC steel High Speed Gearset from CYMA has a 13:1 ratio, which means every 13 motor turns the gearbox will cycle once, which is a step faster than standard 18:1 Airsoft gears. These gears pair perfectly with a high speed motor to provide a demonic rate of fire, as can be seen in the latest upgraded versions of CYMA's Platinum series AEGs. This gearset is designed for use with M120 springs and below only, so should be fine for most UK legal Airsoft AEGs but is not suitable for a DMR rifle with high FPS. This gearset is a version 2/3 set so should work in any AEG with a V2/3 gearbox and many others which share the same gears.
