These brushless motors from Model Motors have been designed specifically for F5J electric thermal gliding and feature a toughened 4mm shaft with the same efficient design and robust construction as all AXi v2 motors. The layout is the same as the "v2 long" motors but this range of F5J motors has a 4mm shaft rather than the 3.17mm of the bog standard v2 motors.

The 2217/20 F5J is intended for use on 3s Li-Po batteries and at 840RPM/V offers plenty of torque for turning a large propeller efficiently. Use this motor in sailplanes up to 1100g (Approx 39oz) on 3s with 12×6 propellers and at least a 20A ESC.

The mounting pattern is the typical 16/19mm and requires M3 screws.

  • AXi 2217/20 840kv v2 Long F5J brushless motor (79g)
