After the installation of the Airmaster prop we were able to get the benefit from the extra horsepower from the turbo 912ULS. We could see between 5 and 8 knots better cruise at 5000 rpms. The most benefit that we get from the prop is when we go to high altitude then it makes the benefit of the turbo charger work correctly. The constant speed controller works excellent and the numbers that Airmaster dialed in for the turbo engine takes any guesswork out of setting the prop. I could not be more satisfied with the prop, the controller and the support that we got from Airmaster when we ordered the prop. Also the installation was very straight forward and easy to complete.
