Model Motors AXI OUTRUNNERS
Model Motors has the most complete selection of OUTRUNNER brushless motors available today. AXI motors are made of the highest quality materials and workmanship. They also have the best warranty on the market today. Every Czech manufactured AXI motor is a highly efficient, high torque, maintenance free rotating can (OUTRUNNER) brushless motor with strong neodym magnets.
The use of a gearbox is NOT necessary. The hardened steel motor shaft is supported by 2 ball bearings in the 22-28 series motors, and 3 ball bearings in the 41-53 series motors. The larger AXI motors easily replace old outdated glow engines. AXI motors fly .40-1.20 size airplanes with more power and authority than the weaker glow engines.
Understanding AXI OUTRUNNERS
Each AXI motor has a 6 digit numbering system. For example: 220834. The first two numbers (22) represent the diameter of the stator (the fixed part in the middle of the motor) in millimeters. The second two numbers (08) represent the length of magnets (attached to the rotating case) in millimeters. The third set of two numbers (34) represents the number of wire winds, also called turns.
When comparing the motors within any series (2208, 2212, etc.) there are several characteristics that you will notice. Motors with higher winds spin slower for every volt of electricity applied, they have a lower Kv (RPM/V). They spin a larger propeller at slower speeds and at a lower current than low turn motors. Motors with lower winds spin faster for every volt of electricity applied, they have a higher Kv (RPM/V). They spin a smaller propeller at higher speeds and at a higher current than high turn motors.
To determine the motor for your model: analyze the character of your airplane, is it sleek and fast, or a slower plane with a lot of drag? For the high speed airplane a low turn motor that spins a small prop fast would be the right choice. For a Trainer or Biplane with a lot more drag, a high turn motor that can spin a much larger prop and produce a lot of thrust at low speed is what you want.
Whatever your airplane, Model Motors makes a high quality OUTRUNNER motor capable of flying it like nothing else.
