Brushless power and efficiency for electric flight!
Not only are Ammo Inrunner Brushless Motors almost twice as efficient as brushed motors, these power plants also offer more value than other inrunners. And with so many models to choose from, you're sure to find the perfect match for whatever type of plane you fly — from tiny indoor flyers to scale giants. 
- Powered by "rare-earth" Neodymium magnets for high torque and unmatched heat resistance — up to 89% efficient.
- With no comms to re-true or brushes to wear out, Ammo Inrunner motors are virtually maintenance-free.
- All Ammo motors feature lightweight aluminum cans and double-shielded bearings.
- Ideal for direct-drive applications or with matched Ammo gearboxes.
- Ready to install, with gold-plated connectors compatible with all ElectriFly brushless ESCs.
