Powerful enough for 2.9kg 3m sailplane

To install this geared motor solid and stable, I strongly recommend to use CNC milled aluminum motor mount sold on this site. This system seemed to be too heavy and long to be supported by a simple FRP plate.
The motor pulled up 2.9kg 3m wingspan F3F sailplane way high with 4 cell 2200mAh lipo.
