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 long shaft variant, is designed for standard M4/AR-15, SMG-5, G3 and P90 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!
