AXI Brushless Motors by Model Motors
AXI brushless outrunners from Model Motors have long been a familiar choice for electric flight, valued by builders who want a dependable motor for sport and scale airplanes. This category gathers AXI motors along with the parts that keep them turning through a long service life.
AXI Motor Range
The lineup here includes sizes such as the AXI 2208/26, AXI 2208/34, AXI 2212/20, and AXI 2212/26, spanning a spread of kv ratings so you can match a motor to the prop and airframe you have in mind. The trailing number in each designation reflects the winding, which influences how fast the motor turns for a given voltage.
Geared and Replacement Parts
For a geared setup, the Model Motors Mini-AC Extreme 1215/9 comes with a gearbox suited to slow, large-prop applications. Replacement bearings for S-300 and S-400 class motors, in the 2208/26 size, help refresh a motor that has seen plenty of use.
Compare the AXI sizes and parts below to suit your setup.
