I have just calculated your speed with 20% slip caused by your propeller. I come to 85km/h.

Why do you have such a motor with low windings ? Your current will be at a high level. Not good for all components. I think a Lipo with 4 or 5 cells could be better. At the same time, a motor with more windings.

The revelotions from you are ok in my opinion. ~40000
