Werner Kohlberger, aeromodelling (Austria): 


Subjective impression of flight

No 3D is to slow to turn up the rpm we need it for programmflying. The speed of the plane is good and slow. The speed downflying is slow too.

Comparison with other propellers

Between this prop and 30x13 3-blade is noiselevel and the slower speed.

Other comments

­
The prop is the overlimit for the ZDZ 180 a prop between this and the 30x13 (maybe 30,5x12) will be the best.
