“Windsor Propeller LLC Rancho Cordova, California. Master Airscrew product line.I wish that there were a choice for overall quality of the product which is between "good" and "very good".Only the packing slip indicated that this is a propeller for electric motors. The propeller has raised characters at the hub indicating 11 x 8 (inch) and 28 x 20 (centimeters). Six different plastic washers are provided to accommodate various motor shaft diameters. The propeller blades are beautifully filleted at the hub (where the stresses are highest). The leading and trailing edges of each blade are thin for increased energy efficiency at high rotational speeds.The instructions say to re- check the balance before using. I used a Du-Bro Tru-Spin Prop Balancer Catalog Number 499. The balance was good enough that I am hesitant to attempt to improve it. Aesthetically, this propeller is very satisfactory for most model aircraft flying. My example has rough edges on the leading and trailing edges and tips of the propeller blades, which I may choose to clean up. There is a 1" long radial scratch on the back side of the tip of one propeller blade (where the bending and shear stresses are lowest, but the centrifugal force is greatest--probably not important inasmuch as the scratch direction is radial). For scale models, I am inclined to spend some time and effort cleaning up the appearance. I admit that I have not installed the propeller on a radio-controlled model aircraft and flown it. The performance is certain to be highly dependent on the individual characteristics of the motor and airframe, the style of flying (e.g., aerobatic competition, pylon racing, etc.), and how wisely the characteristics of the propeller have been chosen accordingly.”
