RE: Master airscrew
Here is a little known fact concerning the MasterAirscrew 3 blade props. I use these props a lot and they are "put it on and forget it" props. From the Tower Hobbies website.
FEATURES: Factory-balanced 3-blade prop has NACA airfoils and holds true pitch.
They have been accurately balanced and create a greater thrust
at lower RPM.
Prop is glass-filled nylon as opposed to a wooden prop.
