Agreed "pattern prop" is a label...however it's a label with a few implications.

"Just as model airplane engines aren't all alike, so props vary quite a bit in quality and durability from make to make. When choosing the best prop for your plane/engine, you should keep several factors in mind. Plane size & weight, airfoil, thrust-to-weight-ratio, engine rpm, brake horsepower, and other factors, like the use of tuned pipes to boost rpm & torque, are handy things to consider when selecting a prop size."

"The nature of Pattern flying demands agility in maneuvers, proper control of airspeed at all times, fast response, and good thrust. Matching the right prop to your engine and plane will make a big difference in every flight, in every maneuver. While engine rpm and a prop's angle of pitch will have a lot to do with the plane's speed, the prop's diameter and pitch will determine the rpm. Power, speed, and control should be balanced out, which means that, for the happiest results, the plane and the engine and the prop need to be properly matched."



Although this is targeting glo power...same thought process also applies to electric power.
