The benfits of the prop seem to be more noticable when i finally got to work on thottle curve adjustment.

The prop seems to pull the model through manuvers with slightly more authority particularly at a more controlled low speed.

The funny thing is that the saito swings the 13x6 at around 10k rpm , but the 14x5N at only 7k rpm.
It does however shift a lot of air and vertical acceleration with the 14x5N is just as good.
