Glider setup

Excellent service as always. Installed this motor in 3m F3b type glider with GM 17x10, hyper spinner and 4s battery, performance was excellent. Had set controller to wind up slowly but by the time it was at full power it was a dot in the sky. It pulled 86A and 1046W.

Nice quality motor, smooth and efficient. Mine pulls 55A on 4S with 14"x9.5" prop so maybe needs bigger prop than Hyperflight's datasheet suggests to maximise power output. Great service from Neil as always

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.
