  • February 12, 2017  -  A brushed motor was chosen because it allows the overall plane to be very light and use a 1 cell battery.  The manufacturer felt using a brushed motor allowed the use of a smaller lighter battery and smaller lighter ESC which creates a lighter plane with better performance.  The downside is the finite life span of a brushed motor.  Since the brushed replacement motor is inexpensive, we recommend purchasing a replacement motor with the plane.
